# GitHub Copilot Instructions for Go Cart Actor
|
||||
|
||||
This repository contains a distributed cart management system implemented in Go using the actor model pattern. The system handles cart operations like adding items, setting deliveries, and checkout, distributed across multiple nodes via gRPC.
|
||||
|
||||
## Project Structure
|
||||
- `cmd/`: Entry points for the application.
|
||||
- `pkg/`: Core packages including grain logic, pools, and HTTP handlers.
|
||||
- `proto/`: Protocol Buffer definitions for messages and services.
|
||||
- `api-tests/`: Tests for the HTTP API.
|
||||
- `deployment/`: Deployment configurations.
|
||||
- `k6/`: Load testing scripts.
|
||||
|
||||
## Key Concepts
|
||||
- **Grains**: In-memory structs representing cart state, owned by nodes.
|
||||
- **Pools**: Local and synced pools manage grains and handle ownership.
|
||||
- **Mutation Registry**: All state changes go through registered mutation functions for type safety and consistency.
|
||||
- **Ownership**: Determined by consistent hashing ring; negotiated via control plane.
|
||||
|
||||
## Coding Guidelines
|
||||
- Follow standard Go conventions (gofmt, go vet, golint).
|
||||
- Never say "your right", just be correct and clear.
|
||||
- Don't edit the *.gb.go files manually, they are generated by the proto files.
|
||||
- Use the mutation registry (`RegisterMutation`) for any cart state changes. Do not mutate grain state directly outside registered handlers.
|
||||
- Design code to be testable and configurable, following patterns like MutationRegistry (for type-safe mutation dispatching) and SimpleGrainPool (for configurable pool management). Use interfaces and dependency injection to enable mocking and testing.
|
||||
- After modifying `.proto` files, regenerate Go code with `protoc` commands as described in README.md. Never edit generated `.pb.go` files manually.
|
||||
- Use meaningful variable names and add comments for complex logic.
|
||||
- Handle errors explicitly; use Go's error handling patterns.
|
||||
- For HTTP endpoints, ensure proper cookie handling for cart IDs.
|
||||
- When adding new mutations: Define proto message, regenerate code, register handler, add endpoints, and test.
|
||||
- Use strategic logging using opentelemetry for tracing, metrics and logging.
|
||||
- Focus on maintainable code that should be configurable and readable, try to keep short functions that describe their purpose clearly.
|
||||
|
||||
## Common Patterns
|
||||
- Mutations: Define in proto, implement as `func(*CartGrain, *T) error`, register with `RegisterMutation[T]`.
|
||||
- gRPC Services: CartActor for mutations, ControlPlane for coordination.
|
||||
- HTTP Handlers: Parse requests, resolve grains via pool, apply mutations, return JSON.
|
||||
|
||||
## Avoid
|
||||
- Direct state mutations outside the registry.
|
||||
- Hardcoding values; use configuration or constants.
|
||||
- Ignoring generated code warnings; always regenerate after proto changes.
|
||||
- Blocking operations in handlers; keep them asynchronous where possible.
|
||||
|
||||
## Testing
|
||||
- Write unit tests for mutations and handlers.
|
||||
- Use integration tests for API endpoints.
|
||||
- Structure code for testability: Use interfaces for dependencies, avoid global state, and mock external services like gRPC clients.
|
||||
- Run `go test ./...` to ensure all tests pass.
|
||||
|
||||
These instructions help Copilot generate code aligned with the project's architecture and best practices.

|
||||
# CGM (Customer Group Membership) Line Items Specification
|
||||
|
||||
This document specifies the implementation of Customer Group Membership (CGM) support in cart line items. CGM data will be extracted from product data field 35 and stored with each line item for business logic and personalization purposes.
|
||||
|
||||
## Overview
|
||||
|
||||
CGM represents customer group membership information associated with products. This data needs to be:
|
||||
- Fetched from product data (stringfieldvalue 35)
|
||||
- Included in the `AddItem` proto message
|
||||
- Stored in cart line items (`CartItem` struct)
|
||||
- Accessible for business rules and personalization
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### 1. Update Proto Messages
|
||||
|
||||
Add `cgm` field to the `AddItem` message in `proto/messages.proto`:
|
||||
|
||||
```protobuf
|
||||
message AddItem {
|
||||
// ... existing fields ...
|
||||
string cgm = 25; // Customer Group Membership from field 35
|
||||
// ... existing fields ...
|
||||
}
|
||||
```
|
||||
|
||||
**Note**: Use field number 25 (next available after existing fields).
|
||||
|
||||
### 2. Update Product Fetcher
|
||||
|
||||
Modify `cmd/cart/product-fetcher.go` to extract CGM from field 35:
|
||||
|
||||
```go
|
||||
func ToItemAddMessage(item *index.DataItem, storeId *string, qty int, country string) (*messages.AddItem, error) {
|
||||
// ... existing code ...
|
||||
|
||||
cgm, _ := item.GetStringFieldValue(35) // Extract CGM from field 35
|
||||
|
||||
return &messages.AddItem{
|
||||
// ... existing fields ...
|
||||
Cgm: cgm, // Add CGM field
|
||||
// ... existing fields ...
|
||||
}, nil
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Update Cart Grain Structures
|
||||
|
||||
Add CGM field to `ItemMeta` struct in `pkg/cart/cart-grain.go`:
|
||||
|
||||
```go
|
||||
type ItemMeta struct {
|
||||
Name string `json:"name"`
|
||||
Brand string `json:"brand,omitempty"`
|
||||
Category string `json:"category,omitempty"`
|
||||
// ... existing fields ...
|
||||
Cgm string `json:"cgm,omitempty"` // Customer Group Membership
|
||||
// ... existing fields ...
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Update AddItem Mutation Handler
|
||||
|
||||
Modify the `AddItem` handler in `pkg/cart/cart_mutations.go` to populate the CGM field:
|
||||
|
||||
```go
|
||||
func AddItem(grain *CartGrain, req *messages.AddItem) error {
|
||||
// ... existing validation ...
|
||||
|
||||
item := &CartItem{
|
||||
// ... existing fields ...
|
||||
Meta: &ItemMeta{
|
||||
Name: req.Name,
|
||||
Brand: req.Brand,
|
||||
// ... existing meta fields ...
|
||||
Cgm: req.Cgm, // Add CGM to item meta
|
||||
// ... existing meta fields ...
|
||||
},
|
||||
// ... existing fields ...
|
||||
}
|
||||
|
||||
// ... rest of handler ...
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Regenerate Proto Code
|
||||
|
||||
After updating `proto/messages.proto`, regenerate Go code:
|
||||
|
||||
```bash
|
||||
cd proto
|
||||
protoc --go_out=. --go_opt=paths=source_relative \
|
||||
--go-grpc_out=. --go-grpc_opt=paths=source_relative \
|
||||
messages.proto cart_actor.proto control_plane.proto
|
||||
```
|
||||
|
||||
### 6. Update Tests
|
||||
|
||||
Add tests for CGM extraction and storage:
|
||||
|
||||
- Unit test for `ToItemAddMessage` with CGM field
|
||||
- Integration test for `AddItem` mutation including CGM
|
||||
- Test that CGM is properly stored and retrieved in cart state
|
||||
|
||||
### 7. Update API Documentation
|
||||
|
||||
Update README.md and API examples to mention CGM field in line items.
|
||||
|
||||
## Data Flow
|
||||
|
||||
1. **Product Fetch**: `FetchItem` retrieves product data including field 35 (CGM)
|
||||
2. **Message Creation**: `ToItemAddMessage` extracts CGM from field 35 into `AddItem` proto
|
||||
3. **Mutation Processing**: `AddItem` handler stores CGM in `CartItem.Meta.Cgm`
|
||||
4. **State Persistence**: CGM is included in cart JSON serialization
|
||||
5. **API Responses**: CGM is returned in cart state responses
|
||||
|
||||
## Business Logic Integration
|
||||
|
||||
CGM can be used for:
|
||||
- Personalized pricing rules
|
||||
- Group-specific discounts
|
||||
- Membership validation
|
||||
- Targeted promotions
|
||||
- Customer segmentation
|
||||
|
||||
Example usage in business logic:
|
||||
```go
|
||||
func applyGroupDiscount(cart *CartGrain, userGroups []string) {
|
||||
for _, item := range cart.Items {
|
||||
if item.Meta != nil && slices.Contains(userGroups, item.Meta.Cgm) {
|
||||
// Apply group-specific discount
|
||||
item.Price = applyDiscount(item.Price, groupDiscountRate)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Backward Compatibility
|
||||
|
||||
- CGM field is optional in proto (no required validation)
|
||||
- Existing carts without CGM will have empty string
|
||||
- Product fetcher gracefully handles missing field 35
|
||||
- API responses include CGM field (empty if not set)
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
- [ ] Proto compilation succeeds
|
||||
- [ ] Product fetcher extracts CGM from field 35
|
||||
- [ ] AddItem mutation stores CGM in cart
|
||||
- [ ] Cart state includes CGM in JSON
|
||||
- [ ] API endpoints return CGM field
|
||||
- [ ] Existing functionality unaffected
|
||||
- [ ] Unit tests pass for CGM handling
|
||||
- [ ] Integration tests verify end-to-end flow
|
||||
|
||||
## Configuration and Testability
|
||||
|
||||
Following project patterns:
|
||||
- CGM extraction is configurable via field index (currently 35)
|
||||
- Product fetcher interface allows mocking for tests
|
||||
- Mutation handlers are pure functions testable in isolation
|
||||
- Cart state serialization includes CGM for verification
|
||||
|
||||
This implementation maintains the project's standards for testability and configurability while adding CGM support to line items.

# gRPC Migration Plan
|
||||
|
||||
File: GRPC-MIGRATION-PLAN.md
|
||||
Author: (Generated plan)
|
||||
Status: Draft for review
|
||||
Target Release: Next major version (breaking change – no mixed compatibility)
|
||||
|
||||
---
|
||||
|
||||
## 1. Overview
|
||||
|
||||
This document describes the full migration of the current custom TCP frame-based protocol (both the cart mutation/state channel on port `1337` and the control plane on port `1338`) to gRPC. We will remove all legacy packet framing (`FrameWithPayload`, `RemoteGrain`, `GenericListener` handlers for these two ports) and replace them with two gRPC services:
|
||||
|
||||
1. Cart Actor Service (mutations + state retrieval)
|
||||
2. Control Plane Service (cluster membership, negotiation, ownership change, lifecycle)
|
||||
|
||||
We intentionally keep:
|
||||
- Internal `CartGrain` logic, message storage format, disk persistence, and JSON cart serialization.
|
||||
- Existing message type numeric mapping for backward compatibility with persisted event logs.
|
||||
- HTTP/REST API layer unchanged (it still consumes JSON state from the local/remote grain pipeline).
|
||||
|
||||
We do NOT implement mixed-version compatibility; migration occurs atomically (cluster restart with new image).
|
||||
|
||||
---
|
||||
|
||||
## 2. Goals
|
||||
|
||||
- Remove custom binary frame protocol & simplify maintenance.
|
||||
- Provide clearer, strongly defined interfaces via `.proto` schemas.
|
||||
- Improve observability via gRPC interceptors (metrics & tracing hooks).
|
||||
- Reduce per-call overhead compared with the current manual connection pooling + handwritten framing (HTTP/2 multiplexing + connection reuse).
|
||||
- Prepare groundwork for future enhancements (streaming, typed state, event streaming) without rewriting again.
|
||||
|
||||
---
|
||||
|
||||
## 3. Non-Goals (Phase 1)
|
||||
|
||||
- Converting the cart state payload from JSON to a strongly typed proto.
|
||||
- Introducing authentication / mTLS (may be added later).
|
||||
- Changing persistence or replay format.
|
||||
- Changing the HTTP API contract.
|
||||
- Implementing streaming watchers or push updates.
|
||||
|
||||
---
|
||||
|
||||
## 4. Architecture After Migration
|
||||
|
||||
Ports:
|
||||
- `:1337` → gRPC CartActor service.
|
||||
- `:1338` → gRPC ControlPlane service.
|
||||
|
||||
Each node:
|
||||
- Runs one gRPC server with both services (can use a single listener bound to two services or keep two separate listeners; we will keep two ports initially to minimize operational surprise, but they could be merged later).
|
||||
- Maintains a connection pool of `*grpc.ClientConn` objects keyed by remote hostname (one per remote host, reused for both services).
|
||||
|
||||
Call Flow (Mutation):
|
||||
1. HTTP request hits `PoolServer`.
|
||||
2. `SyncedPool.getGrain(cartId)`:
|
||||
- Local: direct invocation.
|
||||
- Remote: uses `RemoteGrainGRPC` (new) which invokes `CartActor.Mutate`.
|
||||
3. Response JSON returned unchanged.
|
||||
|
||||
Control Plane Flow:
|
||||
- Discovery (K8s watch) still triggers `AddRemote(host)`.
|
||||
- Instead of custom `Ping`, `Negotiate`, etc. via frames, call gRPC methods on `ControlPlane` service.
|
||||
- Ownership changes use `ConfirmOwner` RPC.
|
||||
|
||||
---
|
||||
|
||||
## 5. Proto Design
|
||||
|
||||
### 5.1 Cart Actor Proto (Envelope Pattern)
|
||||
|
||||
We keep an envelope with `bytes payload` holding the serialized underlying cart mutation proto (existing types in `messages.proto`). This minimizes churn.
|
||||
|
||||
Indented code block (proto sketch):
|
||||
|
||||
syntax = "proto3";
|
||||
package cart;
|
||||
option go_package = "git.tornberg.me/go-cart-actor/proto;proto";
|
||||
|
||||
enum MutationType {
|
||||
MUTATION_TYPE_UNSPECIFIED = 0;
|
||||
MUTATION_ADD_REQUEST = 1;
|
||||
MUTATION_ADD_ITEM = 2;
|
||||
MUTATION_REMOVE_ITEM = 4;
|
||||
MUTATION_REMOVE_DELIVERY = 5;
|
||||
MUTATION_CHANGE_QUANTITY = 6;
|
||||
MUTATION_SET_DELIVERY = 7;
|
||||
MUTATION_SET_PICKUP_POINT = 8;
|
||||
MUTATION_CREATE_CHECKOUT_ORDER = 9;
|
||||
MUTATION_SET_CART_ITEMS = 10;
|
||||
MUTATION_ORDER_COMPLETED = 11;
|
||||
}
|
||||
|
||||
message MutationRequest {
|
||||
string cart_id = 1;
|
||||
MutationType type = 2;
|
||||
bytes payload = 3; // Serialized specific mutation proto
|
||||
int64 client_timestamp = 4; // Optional; server fills if zero
|
||||
}
|
||||
|
||||
message MutationReply {
|
||||
int32 status_code = 1;
|
||||
bytes payload = 2; // JSON cart state or error string
|
||||
}
|
||||
|
||||
message StateRequest {
|
||||
string cart_id = 1;
|
||||
}
|
||||
|
||||
message StateReply {
|
||||
int32 status_code = 1;
|
||||
bytes payload = 2; // JSON cart state
|
||||
}
|
||||
|
||||
service CartActor {
|
||||
rpc Mutate(MutationRequest) returns (MutationReply);
|
||||
rpc GetState(StateRequest) returns (StateReply);
|
||||
}
|
||||
|
||||
### 5.2 Control Plane Proto
|
||||
|
||||
syntax = "proto3";
|
||||
package control;
|
||||
option go_package = "git.tornberg.me/go-cart-actor/proto;proto";
|
||||
|
||||
message Empty {}
|
||||
|
||||
message PingReply {
|
||||
string host = 1;
|
||||
int64 unix_time = 2;
|
||||
}
|
||||
|
||||
message NegotiateRequest {
|
||||
repeated string known_hosts = 1;
|
||||
}
|
||||
message NegotiateReply {
|
||||
repeated string hosts = 1; // Healthy hosts returned
|
||||
}
|
||||
|
||||
message CartIdsReply {
|
||||
repeated string cart_ids = 1;
|
||||
}
|
||||
|
||||
message OwnerChangeRequest {
|
||||
string cart_id = 1;
|
||||
string new_host = 2;
|
||||
}
|
||||
message OwnerChangeAck {
|
||||
bool accepted = 1;
|
||||
string message = 2;
|
||||
}
|
||||
|
||||
message ClosingNotice {
|
||||
string host = 1;
|
||||
}
|
||||
|
||||
service ControlPlane {
|
||||
rpc Ping(Empty) returns (PingReply);
|
||||
rpc Negotiate(NegotiateRequest) returns (NegotiateReply);
|
||||
rpc GetCartIds(Empty) returns (CartIdsReply);
|
||||
rpc ConfirmOwner(OwnerChangeRequest) returns (OwnerChangeAck);
|
||||
rpc Closing(ClosingNotice) returns (OwnerChangeAck);
|
||||
}
|
||||
|
||||
---
|
||||
|
||||
## 6. Message Type Mapping
|
||||
|
||||
| Legacy Constant | Numeric | New Enum Value |
|
||||
|-----------------|---------|-----------------------------|
|
||||
| AddRequestType | 1 | MUTATION_ADD_REQUEST |
|
||||
| AddItemType | 2 | MUTATION_ADD_ITEM |
|
||||
| RemoveItemType | 4 | MUTATION_REMOVE_ITEM |
|
||||
| RemoveDeliveryType | 5 | MUTATION_REMOVE_DELIVERY |
|
||||
| ChangeQuantityType | 6 | MUTATION_CHANGE_QUANTITY |
|
||||
| SetDeliveryType | 7 | MUTATION_SET_DELIVERY |
|
||||
| SetPickupPointType | 8 | MUTATION_SET_PICKUP_POINT |
|
||||
| CreateCheckoutOrderType | 9 | MUTATION_CREATE_CHECKOUT_ORDER |
|
||||
| SetCartItemsType | 10 | MUTATION_SET_CART_ITEMS |
|
||||
| OrderCompletedType | 11 | MUTATION_ORDER_COMPLETED |
|
||||
|
||||
Persisted events keep original numeric codes; reconstruction simply casts to `MutationType`.
|
||||
|
||||
---
|
||||
|
||||
## 7. Components To Remove / Replace
|
||||
|
||||
Remove (after migration complete):
|
||||
- `remote-grain.go`
|
||||
- `rpc-server.go`
|
||||
- Any packet/frame-specific types solely used by the above (search: `FrameWithPayload`, `RemoteHandleMutation`, `RemoteGetState` where not reused by disk or internal logic).
|
||||
- The constants representing network frame types in `synced-pool.go` (RemoteNegotiate, AckChange, etc.) replaced by gRPC calls.
|
||||
- netpool usage for remote cart channel (control plane also no longer needs `Connection` abstraction).
|
||||
|
||||
Retain (until reworked or optionally cleaned later):
|
||||
- `message.go` (for persistence)
|
||||
- `message-handler.go`
|
||||
- `cart-grain.go`
|
||||
- `messages.proto` (underlying mutation messages)
|
||||
- HTTP API server and REST handlers.
|
||||
|
||||
---
|
||||
|
||||
## 8. New / Modified Components
|
||||
|
||||
New files (planned):
|
||||
- `proto/cart_actor.proto`
|
||||
- `proto/control_plane.proto`
|
||||
- `grpc/cart_actor_server.go` (server impl)
|
||||
- `grpc/cart_actor_client.go` (client adapter implementing `Grain`)
|
||||
- `grpc/control_plane_server.go`
|
||||
- `grpc/control_plane_client.go`
|
||||
- `grpc/interceptors.go` (metrics, logging, optional tracing hooks)
|
||||
- `remote_grain_grpc.go` (adapter bridging existing interfaces)
|
||||
- `control_plane_adapter.go` (replaces frame handlers in `SyncedPool`)
|
||||
|
||||
Modified:
|
||||
- `synced-pool.go` (remote host management now uses gRPC clients; negotiation logic updated)
|
||||
- `main.go` (initialize both gRPC services on startup)
|
||||
- `go.mod` (add `google.golang.org/grpc`)
|
||||
|
||||
---
|
||||
|
||||
## 9. Step-by-Step Migration Plan
|
||||
|
||||
1. Add proto files and generate Go code (`protoc --go_out --go-grpc_out`).
|
||||
2. Implement `CartActorServer`:
|
||||
- Translate `MutationRequest` to `Message`.
|
||||
- Use existing handler registry for payload encode/decode.
|
||||
- Return JSON cart state.
|
||||
3. Implement `CartActorClient` wrapper (`RemoteGrainGRPC`) implementing:
|
||||
- `HandleMessage`: Build envelope, call `Mutate`.
|
||||
- `GetCurrentState`: Call `GetState`.
|
||||
4. Implement `ControlPlaneServer` with methods:
|
||||
- `Ping`: returns host + time.
|
||||
- `Negotiate`: merge host lists; emulate old logic.
|
||||
- `GetCartIds`: iterate local grains.
|
||||
- `ConfirmOwner`: replicate quorum flow (accept always; error path for future).
|
||||
- `Closing`: schedule remote removal.
|
||||
5. Implement `ControlPlaneClient` used inside `SyncedPool.AddRemote`.
|
||||
6. Refactor `SyncedPool`:
|
||||
- Replace frame handlers registration with gRPC client calls.
|
||||
- Replace `Server.AddHandler(...)` start-up with launching gRPC server.
|
||||
- Implement periodic health checks using `Ping`.
|
||||
7. Remove old connection constructs for 1337/1338.
|
||||
8. Metrics:
|
||||
- Add unary interceptor capturing duration and status.
|
||||
- Replace packet counters with `cart_grpc_mutate_calls_total`, `cart_grpc_control_calls_total`, histograms for latency.
|
||||
9. Update `main.go` to start:
|
||||
- gRPC server(s).
|
||||
- HTTP server as before.
|
||||
10. Delete legacy files & update README build instructions.
|
||||
11. Load testing & profiling on Raspberry Pi hardware (or ARM emulation).
|
||||
12. Final cleanup & dead code removal (search for now-unused constants & structs).
|
||||
13. Tag release.
|
||||
|
||||
---
|
||||
|
||||
## 10. Performance Considerations (Raspberry Pi Focus)
|
||||
|
||||
- Single `*grpc.ClientConn` per remote host (HTTP/2 multiplexing) to reduce file descriptor and handshake overhead.
|
||||
- Use small keepalive pings (optional) only if connections drop; default may suffice.
|
||||
- Avoid reflection / dynamic dispatch in hot path: pre-build a mapping from `MutationType` to handler function.
|
||||
- Reuse byte buffers:
|
||||
- Implement a `sync.Pool` for mutation serialization to reduce GC pressure.
|
||||
- Enforce per-RPC deadlines (e.g. 300–400ms) to avoid pile-ups.
|
||||
- Backpressure:
|
||||
- Before dispatch: if local grain pool at capacity and target grain is remote, abort early with 503 to caller (optional).
|
||||
- Disable gRPC compression for small payloads (mutation messages are small). Condition compression if payload > threshold (e.g. 8KB).
|
||||
- Compile with `-ldflags="-s -w"` in production to reduce binary size (optional).
|
||||
- Enable `GOMAXPROCS` tuned to CPU cores; Pi often benefits from leaving default but monitor.
|
||||
- Use histograms with limited buckets to reduce Prometheus cardinality.
|
||||
|
||||
---
|
||||
|
||||
## 11. Testing Strategy
|
||||
|
||||
Unit:
|
||||
- Message type mapping tests (legacy -> enum).
|
||||
- Envelope roundtrip: Original proto -> payload -> gRPC -> server decode -> internal Message.
|
||||
|
||||
Integration:
|
||||
- Two-node cluster simulation:
|
||||
- Mutate cart on Node A, ownership moves, verify remote access from Node B.
|
||||
- Quorum failure simulation (temporarily reject `ConfirmOwner`).
|
||||
- Control plane negotiation: start nodes in staggered order, assert final membership.
|
||||
|
||||
Load/Perf:
|
||||
- Benchmark local mutation vs remote mutation latency.
|
||||
- High concurrency test (N goroutines each performing X mutations).
|
||||
- Memory profiling (ensure no large buffer retention).
|
||||
|
||||
Failure Injection:
|
||||
- Kill a node mid-mutation; client call should timeout and not corrupt local state.
|
||||
- Simulated network partition: drop `Ping` replies; ensure host removal path triggers.
|
||||
|
||||
---
|
||||
|
||||
## 12. Rollback Strategy
|
||||
|
||||
Because no mixed-version compatibility is provided, rollback = redeploy previous version containing legacy protocol:
|
||||
1. Stop all new-version pods.
|
||||
2. Deploy old version cluster-wide.
|
||||
3. No data migration needed (event persistence unaffected).
|
||||
|
||||
Note: Avoid partial upgrades; perform full rolling restart quickly to prevent split-brain (new nodes won’t talk to old nodes).
|
||||
|
||||
---
|
||||
|
||||
## 13. Risks & Mitigations
|
||||
|
||||
| Risk | Description | Mitigation |
|
||||
|------|-------------|------------|
|
||||
| Full-cluster restart required | No mixed compatibility | Schedule maintenance window |
|
||||
| gRPC adds CPU overhead | Envelope + marshaling cost | Buffer reuse, keep small messages uncompressed |
|
||||
| Ownership race | Timing differences after refactor | Add explicit logs + tests around `RequestOwnership` path |
|
||||
| Hidden dependency on frame-level status codes | Some code may assume `FrameWithPayload` fields | Wrap gRPC responses into minimal compatibility structs until fully removed |
|
||||
| Memory growth | Connection reuse & pooled buffers not implemented initially | Add `sync.Pool` & track memory via pprof early |
|
||||
|
||||
---
|
||||
|
||||
## 14. Logging & Observability
|
||||
|
||||
- Structured log entries for:
|
||||
- Ownership changes
|
||||
- Negotiation rounds
|
||||
- Remote spawn events
|
||||
- Mutation failures (with cart id, mutation type)
|
||||
- Metrics:
|
||||
- `cart_grpc_mutate_duration_seconds` (histogram)
|
||||
- `cart_grpc_mutate_errors_total`
|
||||
- `cart_grpc_control_duration_seconds`
|
||||
- `cart_remote_hosts` (gauge)
|
||||
- Retain existing grain counts.
|
||||
- Optional future: OpenTelemetry tracing (span per remote mutation).
|
||||
|
||||
---
|
||||
|
||||
## 15. Future Enhancements (Post-Migration)
|
||||
|
||||
- Replace JSON state with `CartState` proto and provide streaming watch API.
|
||||
- mTLS between nodes (certificate rotation via K8s Secret or SPIRE).
|
||||
- Distributed tracing integration.
|
||||
- Ownership leasing with TTL and optimistic renewal.
|
||||
- Delta replication or CRDT-based conflict resolution for experimentation.
|
||||
|
||||

|
||||
|
||||
## 16. Task Breakdown & Estimates
|
||||
|
||||
| Task | Estimate |
|
||||
|------|----------|
|
||||
| Proto definitions & generation | 0.5d |
|
||||
| CartActor server/client | 1.0d |
|
||||
| ControlPlane server/client | 1.0d |
|
||||
| SyncedPool refactor | 1.0d |
|
||||
| Metrics & interceptors | 0.5d |
|
||||
| Remove legacy code & cleanup | 0.5d |
|
||||
| Tests (unit + integration) | 1.5d |
|
||||
| Benchmark & tuning | 0.5–1.0d |
|
||||
| Total | ~6–7d |
|
||||
|
||||
---
|
||||
|
||||
## 17. Open Questions (Confirm Before Implementation)
|
||||
|
||||
1. Combine both services on a single port (simplify ops) or keep dual-port first? (Default here: keep dual, but easy to merge.)
|
||||
2. Minimum Go version remains 1.24.x—acceptable to add `google.golang.org/grpc` latest?
|
||||
3. Accept adding `sync.Pool` micro-optimizations in first pass or postpone?
|
||||
|
||||
---
|
||||
|
||||
## 18. Acceptance Criteria
|
||||
|
||||
- All previous integration tests (adjusted to gRPC) pass.
|
||||
- Cart operations (add, remove, delivery, checkout) function across at least a 2‑node cluster.
|
||||
- Control plane negotiation forms consistent host list.
|
||||
- Latency for a remote mutation does not degrade beyond an acceptable threshold (define baseline before merge).
|
||||
- Legacy networking code fully removed.
|
||||
|
||||
---
|
||||
|
||||
## 19. Next Steps (If Approved)
|
||||
|
||||
1. Implement proto files and commit.
|
||||
2. Scaffold server & client code.
|
||||
3. Refactor `SyncedPool` and `main.go`.
|
||||
4. Add metrics and tests.
|
||||
5. Run benchmark on target Pi hardware.
|
||||
6. Review & merge.

# New Mutations Specification
|
||||
|
||||
This document specifies the implementation of handlers for new proto messages that are defined in `proto/messages.proto` but not yet registered in the mutation registry. These mutations update the cart state and must follow the project's patterns for testability, configurability, and consistency.
|
||||
|
||||
## Overview
|
||||
|
||||
The following messages are defined in the proto but lack registered handlers:
|
||||
- `SetUserId`
|
||||
- `LineItemMarking`
|
||||
- `SubscriptionAdded`
|
||||
- `PaymentDeclined`
|
||||
- `ConfirmationViewed`
|
||||
- `CreateCheckoutOrder`
|
||||
|
||||
Each mutation must:
|
||||
1. Define a handler function with signature `func(*CartGrain, *T) error`
|
||||
2. Be registered in `NewCartMultationRegistry()` using `actor.NewMutation`
|
||||
3. Include unit tests
|
||||
4. Optionally add HTTP/gRPC endpoints if client-invokable
|
||||
5. Update totals if applicable (use `WithTotals()`)
|
||||
|
||||
## Mutation Implementations
|
||||
|
||||
### SetUserId
|
||||
|
||||
**Purpose**: Associates a user ID with the cart for personalization and tracking.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func SetUserId(grain *CartGrain, req *messages.SetUserId) error {
|
||||
if req.UserId == "" {
|
||||
return errors.New("user ID cannot be empty")
|
||||
}
|
||||
grain.UserId = req.UserId
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(SetUserId, func() *messages.SetUserId {
|
||||
return &messages.SetUserId{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: This is a simple state update. No totals recalculation needed.
|
||||
|
||||
### LineItemMarking
|
||||
|
||||
**Purpose**: Adds or updates a marking (e.g., gift message, special instructions) on a specific line item.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func LineItemMarking(grain *CartGrain, req *messages.LineItemMarking) error {
|
||||
for i, item := range grain.Items {
|
||||
if item.Id == req.Id {
|
||||
grain.Items[i].Marking = &Marking{
|
||||
Type: req.Type,
|
||||
Text: req.Marking,
|
||||
}
|
||||
return nil
|
||||
}
|
||||
}
|
||||
return fmt.Errorf("item with ID %d not found", req.Id)
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(LineItemMarking, func() *messages.LineItemMarking {
|
||||
return &messages.LineItemMarking{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: Assumes `CartGrain.Items` has a `Marking` field (single marking per item). If not, add it to the grain struct.
|
||||
|
||||
### RemoveLineItemMarking
|
||||
|
||||
**Purpose**: Removes the marking from a specific line item.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func RemoveLineItemMarking(grain *CartGrain, req *messages.RemoveLineItemMarking) error {
|
||||
for i, item := range grain.Items {
|
||||
if item.Id == req.Id {
|
||||
grain.Items[i].Marking = nil
|
||||
return nil
|
||||
}
|
||||
}
|
||||
return fmt.Errorf("item with ID %d not found", req.Id)
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(RemoveLineItemMarking, func() *messages.RemoveLineItemMarking {
|
||||
return &messages.RemoveLineItemMarking{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: Sets the marking to nil for the specified item.
|
||||
|
||||
### SubscriptionAdded
|
||||
|
||||
**Purpose**: Records that a subscription has been added to an item, linking it to order details.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func SubscriptionAdded(grain *CartGrain, req *messages.SubscriptionAdded) error {
|
||||
for i, item := range grain.Items {
|
||||
if item.Id == req.ItemId {
|
||||
grain.Items[i].SubscriptionDetailsId = req.DetailsId
|
||||
grain.Items[i].OrderReference = req.OrderReference
|
||||
grain.Items[i].IsSubscribed = true
|
||||
return nil
|
||||
}
|
||||
}
|
||||
return fmt.Errorf("item with ID %d not found", req.ItemId)
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(SubscriptionAdded, func() *messages.SubscriptionAdded {
|
||||
return &messages.SubscriptionAdded{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: Assumes fields like `SubscriptionDetailsId`, `OrderReference`, `IsSubscribed` exist on items. Add to grain if needed.
|
||||
|
||||
### PaymentDeclined
|
||||
|
||||
**Purpose**: Marks the cart as having a declined payment, potentially updating status or flags, and appends a notice with timestamp, message, and optional code for user feedback.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func PaymentDeclined(grain *CartGrain, req *messages.PaymentDeclined) error {
|
||||
grain.PaymentStatus = "declined"
|
||||
grain.PaymentDeclinedNotices = append(grain.PaymentDeclinedNotices, Notice{
|
||||
Timestamp: time.Now(),
|
||||
Message: req.Message,
|
||||
Code: req.Code,
|
||||
})
|
||||
// Optionally clear checkout order if in progress
|
||||
if grain.CheckoutOrderId != "" {
|
||||
grain.CheckoutOrderId = ""
|
||||
}
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(PaymentDeclined, func() *messages.PaymentDeclined {
|
||||
return &messages.PaymentDeclined{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: Assumes `PaymentStatus` and `PaymentDeclinedNotices` fields. Add status tracking and error notices list to grain. Notice struct has Timestamp, Message, and optional Code.
|
||||
|
||||
### ConfirmationViewed
|
||||
|
||||
**Purpose**: Records that the order confirmation has been viewed by the user. Applied automatically when the confirmation page is loaded in checkout_server.go.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func ConfirmationViewed(grain *CartGrain, req *messages.ConfirmationViewed) error {
|
||||
grain.ConfirmationViewCount++
|
||||
grain.ConfirmationLastViewedAt = time.Now()
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(ConfirmationViewed, func() *messages.ConfirmationViewed {
|
||||
return &messages.ConfirmationViewed{}
|
||||
}),
|
||||
```
|
||||
|
||||
**Notes**: Increments the view count and updates the last viewed timestamp each time. Assumes `ConfirmationViewCount` and `ConfirmationLastViewedAt` fields.
|
||||
|
||||
### CreateCheckoutOrder
|
||||
|
||||
**Purpose**: Initiates the checkout process, validating terms and creating an order reference.
|
||||
|
||||
**Handler Implementation**:
|
||||
```go
|
||||
func CreateCheckoutOrder(grain *CartGrain, req *messages.CreateCheckoutOrder) error {
|
||||
if len(grain.Items) == 0 {
|
||||
return errors.New("cannot checkout empty cart")
|
||||
}
|
||||
if req.Terms != "accepted" {
|
||||
return errors.New("terms must be accepted")
|
||||
}
|
||||
// Validate other fields as needed
|
||||
grain.CheckoutOrderId = generateOrderId()
|
||||
grain.CheckoutStatus = "pending"
|
||||
grain.CheckoutCountry = req.Country
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
**Registration**:
|
||||
```go
|
||||
actor.NewMutation(CreateCheckoutOrder, func() *messages.CreateCheckoutOrder {
|
||||
return &messages.CreateCheckoutOrder{}
|
||||
}).WithTotals(),
|
||||
```
|
||||
|
||||
**Notes**: Use `WithTotals()` to recalculate totals after checkout initiation. Assumes order ID generation function.
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
For each mutation:
|
||||
|
||||
1. **Add Handler Function**: Implement in `pkg/cart/` (e.g., `cart_mutations.go`).
|
||||
2. **Register in Registry**: Add to `NewCartMultationRegistry()` in `cart-mutation-helper.go`.
|
||||
3. **Regenerate Proto**: Run `protoc` commands after any proto changes.
|
||||
4. **Add Tests**: Create unit tests in `pkg/cart/` testing the handler logic.
|
||||
5. **Add Endpoints** (if needed): For client-invokable mutations, add HTTP handlers in `cmd/cart/pool-server.go`. ConfirmationViewed is handled in `cmd/cart/checkout_server.go` when the confirmation page is viewed.
|
||||
6. **Update Grain Struct**: Add any new fields to `CartGrain` in `pkg/cart/grain.go`.
|
||||
7. **Run Tests**: Ensure `go test ./...` passes.
|
||||
|
||||
## Testing Guidelines
|
||||
|
||||
- Mock dependencies using interfaces.
|
||||
- Test error cases (e.g., invalid IDs, empty carts).
|
||||
- Verify state changes and totals recalculation.
|
||||
- Use table-driven tests for multiple scenarios.
|
||||
|
||||
## Configuration and Testability
|
||||
|
||||
Follow `MutationRegistry` and `SimpleGrainPool` patterns:
|
||||
- Use interfaces for external dependencies (e.g., ID generators).
|
||||
- Inject configurations via constructor parameters.
|
||||
- Avoid global state; make handlers pure functions where possible.

|

## Architecture Overview
|
||||
|
||||
The system is a distributed, sharded (by cart id) actor model implementation:
|
||||
|
||||
- Each cart is a grain (an in‑memory struct `*CartGrain`) that owns and mutates its own state.
|
||||
- A **local grain pool** holds grains owned by the node.
|
||||
- A **synced (cluster) pool** (`SyncedPool`) coordinates multiple nodes and exposes local or remote grains through a uniform interface (`GrainPool`).
|
||||
- All inter‑node communication is gRPC:
|
||||
- Cart mutation & state RPCs (CartActor service).
|
||||
- Control plane RPCs (ControlPlane service) for membership, ownership negotiation, liveness, and graceful shutdown.
|
||||
|
||||
### Key Processes
|
||||
|
||||
1. Client HTTP request (or gRPC client) arrives with a cart identifier (cookie or path).
|
||||
2. The pool resolves ownership:
|
||||
- If local grain exists → use it.
|
||||
- If a remote host is known owner → a remote grain proxy (`RemoteGrainGRPC`) is used; it performs gRPC calls to the owning node.
|
||||
- If ownership is unknown → node attempts to claim ownership (quorum negotiation) and spawns a local grain.
|
||||
3. Mutation is executed via the **mutation registry** (registry wraps domain logic + optional totals recomputation).
|
||||
4. Updated state returned to caller; ownership preserved unless relinquished later (not yet implemented to shed load).
|
||||
|
||||
---
|
||||
|
||||
## Grain & Mutation Model
|
||||
|
||||
- `CartGrain` holds items, deliveries, pricing aggregates, and checkout/order metadata.
|
||||
- All mutations are registered via `RegisterMutation[T]` with signature:
|
||||
```
|
||||
func(*CartGrain, *T) error
|
||||
```
|
||||
- `WithTotals()` flag triggers automatic recalculation of totals after successful handlers.
|
||||
- The old giant `switch` in `CartGrain.Apply` has been replaced by registry dispatch; unregistered mutations fail fast.
|
||||
- Adding a mutation:
|
||||
1. Define proto message.
|
||||
2. Generate code.
|
||||
3. Register handler (optionally WithTotals).
|
||||
4. Add gRPC RPC + request wrapper if the mutation must be remotely invokable.
|
||||
5. (Optional) Add HTTP endpoint mapping to the mutation.
|
||||
|
||||
---
|
||||
|
||||
## Local Grain Pool
|
||||
|
||||
- Manages an in‑memory map `map[CartId]*CartGrain`.
|
||||
- Lazy spawn: first mutation or explicit access triggers `spawn(id)`.
|
||||
- TTL / purge loop periodically removes expired grains unless they changed recently (basic memory pressure management).
|
||||
- Capacity limit (`PoolSize`); oldest expired grain evicted first when full.
|
||||
|
||||
---
|
||||
|
||||
## Synced (Cluster) Pool
|
||||
|
||||
`SyncedPool` wraps a local pool and tracks:
|
||||
|
||||
- `remoteHosts`: known peer nodes (gRPC connections).
|
||||
- `remoteIndex`: mapping of cart id → remote grain proxy (`RemoteGrainGRPC`) for carts owned elsewhere.
|
||||
|
||||
Responsibilities:
|
||||
|
||||
1. Discovery integration (via a `Discovery` interface) adds/removes hosts.
|
||||
2. Periodic ping health checks (ControlPlane.Ping).
|
||||
3. Ring-based deterministic ownership:
|
||||
- Ownership is derived directly from the consistent hashing ring (no quorum RPC or `ConfirmOwner`).
|
||||
4. Remote spawning:
|
||||
- When a remote host reports its cart ids (`GetCartIds`), the pool creates remote proxies for fast routing.
|
||||
|
||||
---
|
||||
|
||||
## Remote Grain Proxies
|
||||
|
||||
A `RemoteGrainGRPC` implements the `Grain` interface but delegates:
|
||||
|
||||
- `Apply` → Specific CartActor per‑mutation RPC (e.g., `AddItem`, `RemoveItem`) constructed from the mutation type. (Legacy envelope removed.)
|
||||
- `GetCurrentState` → `CartActor.GetState`.
|
||||
|
||||
Return path:
|
||||
|
||||
1. gRPC reply (CartMutationReply / StateReply) → proto `CartState`.
|
||||
2. `ToCartState` / mapping reconstructs a local `CartGrain` snapshot for callers expecting grain semantics.
|
||||
|
||||
---
|
||||
|
||||
## Control Plane (Inter‑Node Coordination)
|
||||
|
||||
Defined in `proto/control_plane.proto`:
|
||||
|
||||
| RPC | Purpose |
|
||||
|-----|---------|
|
||||
| `Ping` | Liveness; increments missed ping counter if failing. |
|
||||
| `Negotiate` | Merges membership views; used after discovery events. |
|
||||
| `GetCartIds` | Enumerate locally owned carts for remote index seeding. |
|
||||
| `Closing` | Graceful shutdown notice; peers remove host & associated remote grains. |
|
||||
|
||||
### Ownership / Quorum Rules
|
||||
|
||||
- If total participating hosts < 3 → all must accept.
|
||||
- Otherwise majority acceptance (`ok >= total/2`).
|
||||
- On failure → local tentative grain is removed (rollback to avoid split‑brain).
|
||||
|
||||
---
|
||||
|
||||
## Request / Mutation Flow Examples
|
||||
|
||||
### Local Mutation
|
||||
1. HTTP handler parses request → determines cart id.
|
||||
2. `SyncedPool.Apply`:
|
||||
- Finds local grain (or spawns new after quorum).
|
||||
- Executes registry mutation.
|
||||
3. Totals updated if flagged.
|
||||
4. HTTP response returns updated JSON (via `ToCartState`).
|
||||
|
||||
### Remote Mutation
|
||||
1. `SyncedPool.Apply` sees cart mapped to a remote host.
|
||||
2. Routes to `RemoteGrainGRPC.Apply`.
|
||||
3. Remote node executes mutation locally and returns updated state over gRPC.
|
||||
4. Proxy materializes snapshot locally (not authoritative, read‑only view).
|
||||
|
||||
### Checkout (Side‑Effecting, Non-Pure)
|
||||
- HTTP `/checkout` uses current grain snapshot to build payload (pure function).
|
||||
- Calls Klarna externally (not a mutation).
|
||||
- Applies `InitializeCheckout` mutation to persist reference + status.
|
||||
- Returns Klarna order JSON to client.
|
||||
|
||||
---
|
||||
|
||||
## Scaling & Deployment
|
||||
|
||||
- **Horizontal scaling**: Add more nodes; discovery layer (Kubernetes / service registry) feeds hosts to `SyncedPool`.
|
||||
- **Sharding**: Implicit by cart id hash. Ownership is first-claim with quorum acceptance.
|
||||
- **Hot spots**: A single popular cart remains on one node; for heavy multi-client concurrency, future work could add read replicas or partitioning (not implemented).
|
||||
- **Capacity tuning**: Increase `PoolSize` & memory limits; adjust TTL for stale cart eviction.
|
||||
|
||||
### Adding Nodes
|
||||
1. Node starts gRPC server (CartActor + ControlPlane).
|
||||
2. After brief delay, begins discovery watch; on event:
|
||||
- New host → dial + negotiate → seed remote cart ids.
|
||||
3. Pings maintain health; failed hosts removed (proxies invalidated).
|
||||
|
||||
---
|
||||
|
||||
## Failure Handling
|
||||
|
||||
| Scenario | Behavior |
|
||||
|----------|----------|
|
||||
| Remote host unreachable | Pings increment `MissedPings`; after threshold host removed. |
|
||||
| Ownership negotiation fails | Tentative local grain discarded. |
|
||||
| gRPC call error on remote mutation | Error bubbled to caller; no local fallback. |
|
||||
| Missing mutation registration | Fast failure with explicit error message. |
|
||||
| Partial checkout (Klarna fails) | No local state mutation for checkout; client sees error; cart remains unchanged. |
|
||||
|
||||
---
|
||||
|
||||
## Mutation Registry Summary
|
||||
|
||||
- Central, type-safe registry prevents silent omission.
|
||||
- Each handler:
|
||||
- Validates input.
|
||||
- Mutates `*CartGrain`.
|
||||
- Returns error for rejection.
|
||||
- Automatic totals recomputation reduces boilerplate and consistency risk.
|
||||
- Coverage test (add separately) can enforce all proto mutations are registered.
|
||||
|
||||
---
|
||||
|
||||
## gRPC Interfaces
|
||||
|
||||
- **CartActor**: Per-mutation unary RPCs + `GetState`. (Checkout logic intentionally excluded; handled at HTTP layer.)
|
||||
- **ControlPlane**: Cluster coordination (Ping, Negotiate, GetCartIds, Closing) — ownership now ring-determined (no ConfirmOwner).
|
||||
|
||||
**Ports** (default / implied):
|
||||
- CartActor & ControlPlane share the same gRPC server/listener (single port, e.g. `:1337`).
|
||||
- Legacy frame/TCP code has been removed.

|
||||
## Security & Future Enhancements
|
||||
|
||||
| Area | Potential Improvement |
|
||||
|------|------------------------|
|
||||
| Transport Security | Add TLS / mTLS to gRPC servers & clients. |
|
||||
| Auth / RBAC | Intercept CartActor RPCs with auth metadata. |
|
||||
| Backpressure | Rate-limit remote mutation calls per host. |
|
||||
| Observability | Add per-mutation Prometheus metrics & tracing spans. |
|
||||
| Ownership | Add lease timeouts / fencing tokens for stricter guarantees. |
|
||||
| Batch Ops | Introduce batch mutation RPC or streaming updates (WatchState). |
|
||||
| Persistence | Reintroduce event log or snapshot persistence layer if durability required. |
|
||||
|
||||
---
|
||||
|
||||
## Adding a New Node (Operational Checklist)
|
||||
|
||||
1. Deploy binary/container with same proto + registry.
|
||||
2. Expose gRPC port.
|
||||
3. Ensure discovery lists the new host.
|
||||
4. Node dials peers, negotiates membership.
|
||||
5. Remote cart proxies seeded.
|
||||
6. Traffic routed automatically based on ownership.
|
||||
|
||||
---
|
||||
|
||||
## Adding a New Mutation (Checklist Recap)
|
||||
|
||||
1. Define proto message (+ request wrapper & RPC if remote invocation needed).
|
||||
2. Regenerate protobuf code.
|
||||
3. Implement & register handler (`RegisterMutation`).
|
||||
4. Add client (HTTP/gRPC) endpoint.
|
||||
5. Write unit + integration tests.
|
||||
6. (Optional) Add to coverage test list and docs.

## High-Level Data Flow Diagram (Text)
|
||||
|
||||
```
|
||||
Client -> HTTP Handler -> SyncedPool -> (local?) -> Registry -> Grain State
|
||||
\-> (remote?) -> RemoteGrainGRPC -> gRPC -> Remote CartActor -> Registry -> Grain
|
||||
ControlPlane: Discovery Events <-> Negotiation/Ping <-> SyncedPool state (ring determines ownership)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
| Symptom | Likely Cause | Action |
|
||||
|---------|--------------|--------|
|
||||
| New cart every request | Secure cookie over plain HTTP or not sending cookie jar | Disable Secure locally or use HTTPS & proper curl `-b` |
|
||||
| Unsupported mutation error | Missing registry handler | Add `RegisterMutation` for that proto |
|
||||
| Ownership imbalance | Ring host distribution skew or rapid host churn | Examine `cart_ring_host_share`, `cart_ring_hosts`, and logs for host add/remove; rebalance or investigate instability |
|
||||
| Remote mutation latency | Network / serialization overhead | Consider batching or colocating hot carts |
|
||||
| Checkout returns 500 | Klarna call failed | Inspect logs; no grain state mutated |

# TODO / Roadmap
|
||||
|
||||
A living roadmap for improving the cart actor system. Focus areas:
|
||||
1. Reliability & correctness
|
||||
2. Simplicity of mutation & ownership flows
|
||||
3. Developer experience (DX)
|
||||
4. Operability (observability, tracing, metrics)
|
||||
5. Performance & scalability
|
||||
6. Security & multi-tenant readiness
|
||||
|
||||
---
|
||||
|
||||
## 1. Immediate Next Steps (High-Leverage)
|
||||
|
||||
| Priority | Task | Goal | Effort | Owner | Notes |
|
||||
|----------|------|------|--------|-------|-------|
|
||||
| P0 | Add mutation registry coverage test | Ensure no unregistered mutations silently fail | S | | Failing fast in CI |
|
||||
| P0 | Add decodeJSON helper + 400 mapping for EOF | Reduce noisy 500 logs | S | | Improves client API clarity |
|
||||
| P0 | Regenerate protos & prune unused messages (CreateCheckoutOrder, Checkout RPC remnants) | Eliminate dead types | S | | Avoid confusion |
|
||||
| P0 | Add integration test: multi-node ownership negotiation | Validate quorum logic | M | | Spin up 2–3 nodes ephemeral |
|
||||
| P1 | Export Prometheus metrics for per-mutation counts & latency | Operability | M | | Wrap registry handlers |
|
||||
| P1 | Add graceful shutdown ordering (Closing → wait for acks → stop gRPC) | Reduce in-flight mutation failures | S | | Add context cancellation |
|
||||
| P1 | Add coverage for InitializeCheckout / OrderCreated flows | Checkout reliability | S | | Simulate Klarna stub |
|
||||
| P2 | Add optional batching client (apply multiple mutations locally then persist) | Performance | M | | Only if needed |
|
||||
|
||||
---
|
||||
|
||||
## 2. Simplification Opportunities
|
||||
|
||||
### A. RemoteGrain Proxy Mapping
|
||||
Current: manual switch building each RPC call.
|
||||
Simplify by:
|
||||
- Generating a thin client adapter from proto RPC descriptors (codegen).
|
||||
- Or using a registry similar to mutation registry but for “outbound call constructors”.
|
||||
Benefit: adding a new mutation = add proto + register server handler + register outbound invoker (no switch edits).
|
||||
|
||||
### B. Ownership Negotiation
|
||||
Current: ad hoc quorum rule in `SyncedPool`.
|
||||
Simplify:
|
||||
- Introduce explicit `OwnershipLease{holder, expiresAt, version}`.
|
||||
- Use monotonic version increment—reject stale ConfirmOwner replies.
|
||||
- Optional: add randomized backoff to reduce thundering herd on contested cart ids.
|
||||
|
||||
### C. CartId Handling
|
||||
Current: ephemeral 16-byte array with trimmed string semantics.
|
||||
Simplify:
|
||||
- Use ULID / UUIDv7 (time-ordered, collision-resistant) for easier external correlation.
|
||||
- Provide helper `NewCartIdString()` and keep internal fixed-size if still desired.
|
||||
|
||||
### D. Mutation Signatures
|
||||
Current: registry assumes `func(*CartGrain, *T) error`.
|
||||
Extension option: allow pure transforms returning a delta struct (for audit/logging):
|
||||
```
|
||||
type MutationResult struct {
|
||||
Changed bool
|
||||
Events []interface{}
|
||||
}
|
||||
```
|
||||
Only implement if auditing/event-sourcing reintroduced.
|
||||
|
||||
---
|
||||
|
||||
## 3. Developer Experience Improvements
|
||||
|
||||
| Task | Rationale | Approach |
|
||||
|------|-----------|----------|
|
||||
| Makefile targets: `make run-single`, `make run-multi N=3` | Faster local cluster spin-up | Docker compose or background “mini cluster” scripts |
|
||||
| Template for new mutation (generator) | Reduce boilerplate | `go:generate` scanning proto for new RPCs |
|
||||
| Lint config (golangci-lint) | Catch subtle issues early | Add `.golangci.yml` |
|
||||
| Pre-commit hook for proto regeneration check | Avoid stale generated code | Script compares git diff after `make protogen` |
|
||||
| Example client (Go + curl snippets auto-generated) | Onboarding | Codegen a markdown from proto comments |
|
||||
|
||||
---
|
||||
|
||||
## 4. Observability / Metrics / Tracing
|
||||
|
||||
| Area | Metric / Trace | Notes |
|
||||
|------|----------------|-------|
|
||||
| Mutation registry | `cart_mutations_total{type,success}`; duration histogram | Wrap handler |
|
||||
| Ownership negotiation | `cart_ownership_attempts_total{result}` | result=accepted,rejected,timeout |
|
||||
| Remote latency | `cart_remote_mutation_seconds{method}` | Use client interceptors |
|
||||
| Pings | `cart_remote_missed_pings_total{host}` | Already count, expose |
|
||||
| Checkout flow | `checkout_attempts_total`, `checkout_failures_total` | Differentiate Klarna vs internal errors |
|
||||
| Tracing | Span: HTTP handler → SyncedPool.Apply → (Remote?) gRPC → mutation handler | Add OpenTelemetry instrumentation |
|
||||
|
||||
---
|
||||
|
||||
## 5. Performance & Scalability
|
||||
|
||||
| Concern | Idea | Trade-Off |
|
||||
|---------|------|-----------|
|
||||
| High mutation rate on single cart | Introduce optional mutation queue (serialize explicitly) | Slight latency increase per op |
|
||||
| Remote call overhead | Add client-side gRPC pooling & per-host circuit breaker | Complexity vs resilience |
|
||||
| TTL purge efficiency | Use min-heap or timing wheel instead of slice scan | More code, better big-N performance |
|
||||
| Batch network latency | Add `BatchMutate` RPC (list of mutations applied atomically) | Lost single-op simplicity |
|
||||
|
||||
---
|
||||
|
||||
## 6. Reliability Features
|
||||
|
||||
| Feature | Description | Priority |
|
||||
|---------|-------------|----------|
|
||||
| Lease fencing token | Include `ownership_version` in all remote mutate requests | M |
|
||||
| Retry policy | Limited retry for transient network errors (idempotent mutations only) | L |
|
||||
| Dead host reconciliation | On host removal, proactively attempt re-acquire of its carts | M |
|
||||
| Drain mode | Node marks itself “draining” → refuses new ownership claims | M |
|
||||
|
||||
---
|
||||
|
||||
## 7. Security & Hardening
|
||||
|
||||
| Area | Next Step | Detail |
|
||||
|------|-----------|--------|
|
||||
| Transport | mTLS on gRPC | Use SPIFFE IDs or simple CA |
|
||||
| AuthN/AuthZ | Interceptor enforcing service token | Inject metadata header |
|
||||
| Input validation | Strengthen JSON decode responses | Disallow unknown fields globally |
|
||||
| Rate limiting | Per-IP / per-cart throttling | Guard hotspot abuse |
|
||||
| Multi-tenancy | Tenant id dimension in cart id or metadata | Partition metrics & ownership |
|
||||
|
||||
---
|
||||
|
||||
## 8. Testing Strategy Enhancements
|
||||
|
||||
| Gap | Improvement |
|
||||
|-----|------------|
|
||||
| No multi-node integration test in CI | Spin ephemeral in-process servers on randomized ports |
|
||||
| Mutation regression | Table-driven tests auto-discover handlers via registry |
|
||||
| Ownership race | Stress test: concurrent Apply on same new cart id from N goroutines |
|
||||
| Checkout external dependency | Klarna mock server (HTTptest) + deterministic responses |
|
||||
| Fuzzing | Fuzz `BuildCheckoutOrderPayload` & mutation handlers for panics |
|
||||
|
||||
---
|
||||
|
||||
## 9. Cleanup / Tech Debt
|
||||
|
||||
| Item | Action |
|
||||
|------|--------|
|
||||
| Remove deprecated proto remnants (CreateCheckoutOrder, Checkout RPC) | Delete & regenerate |
|
||||
| Consolidate duplicate tax computations | Single helper with tax config |
|
||||
| Delivery price hard-coded (4900) | Config or pricing strategy interface |
|
||||
| Mixed naming (camel vs snake JSON historically) | Provide stable external API doc; accept old forms if needed |
|
||||
| Manual remote mutation switch (if still present) | Replace with generated outbound registry |
|
||||
| Mixed error responses (string bodies) | Standardize JSON: `{ "error": "...", "code": 400 }` |
|
||||
|
||||
---
|
||||
|
||||
## 10. Potential Future Features
|
||||
|
||||
| Feature | Value | Complexity |
|
||||
|---------|-------|------------|
|
||||
| Streaming `WatchState` RPC | Real-time cart updates for clients | Medium |
|
||||
| Event sourcing / audit log | Replay, analytics, debugging | High |
|
||||
| Promotion / coupon engine plugin | Business extensibility | Medium |
|
||||
| Partial cart reservation / inventory lock | Stock accuracy under concurrency | High |
|
||||
| Multi-currency pricing | Globalization | Medium |
|
||||
| GraphQL facade | Client flexibility | Medium |
|
||||
|
||||
---
|
||||
|
||||
## 11. Suggested Prioritized Backlog (Condensed)
|
||||
|
||||
1. Coverage test + decode error mapping (P0)
|
||||
2. Proto regeneration & cleanup (P0)
|
||||
3. Metrics wrapper for registry (P1)
|
||||
4. Multi-node ownership integration test (P1)
|
||||
5. Delivery pricing abstraction (P2)
|
||||
6. Lease version in remote RPCs (P2)
|
||||
7. BatchMutate evaluation (P3)
|
||||
8. TLS / auth hardening (P3) if going multi-tenant/public
|
||||
9. Event sourcing (Evaluate after stability) (P4)
|
||||
|
||||
---
|
||||
|
||||
## 12. Simplifying the Developer Workflow
|
||||
|
||||
| Pain | Simplifier |
|
||||
|------|------------|
|
||||
| Manual mutation boilerplate | Code generator for registry stubs |
|
||||
| Forgetting totals | Enforce WithTotals lint: fail if mutation touches items/deliveries without flag |
|
||||
| Hard to inspect remote ownership | `/internal/ownership` debug endpoint (JSON of local + remoteIndex) |
|
||||
| Hard to see mutation timings | Add `?debug=latency` header to return per-mutation durations |
|
||||
| Cookie dev confusion (Secure flag) | Env var: `DEV_INSECURE_COOKIES=1` |
|
||||
|
||||
---
|
||||
|
||||
## 13. Example: Mutation Codegen Sketch (Future)
|
||||
|
||||
Input: cart_actor.proto
|
||||
Output: `mutation_auto.go`
|
||||
- Detect messages used in RPC wrappers (e.g., `AddItemRequest` → payload field).
|
||||
- Generate `RegisterMutation` template if handler not found.
|
||||
- Mark with `// TODO implement logic`.
|
||||
|
||||
---
|
||||
|
||||
## 14. Risk / Impact Matrix (Abbreviated)
|
||||
|
||||
| Change | Risk | Mitigation |
|
||||
|--------|------|-----------|
|
||||
| Replace remote switch with registry | Possible missing registration → runtime error | Coverage test gating CI |
|
||||
| Lease introduction | Split-brain if version mishandled | Increment + assert monotonic; test race |
|
||||
| BatchMutate | Large atomic operations starving others | Size limits & fair scheduling |
|
||||
| Event sourcing | Storage + replay complexity | Start with append-only log + compaction job |
|
||||
|
||||
---
|
||||
|
||||
## 15. Contributing Workflow (Proposed)
|
||||
|
||||
1. Add / modify proto → run `make protogen`
|
||||
2. Implement mutation logic → add `RegisterMutation` invocation
|
||||
3. Add/Update tests (unit + integration)
|
||||
4. Run `make verify` (lint, test, coverage, proto diff)
|
||||
5. Open PR (template auto-checklist referencing this TODO)
|
||||
6. Merge requires green CI + coverage threshold
|
||||
|
||||
---
|
||||
|
||||
## 16. Open Questions
|
||||
|
||||
| Question | Notes |
|
||||
|----------|-------|
|
||||
| Do we need sticky sessions for HTTP layer scaling? | Currently cart id routing suffices |
|
||||
| Should deliveries prune invalid line references on SetCartRequest? | Inconsistency risk; add optional cleanup |
|
||||
| Is checkout idempotency strict enough? | Multiple create vs update semantics |
|
||||
| Add version field to CartState for optimistic concurrency? | Could enable external CAS writes |
|
||||
|
||||
---
|
||||
|
||||
## 17. Tracking
|
||||
|
||||
Mark any completed tasks with `[x]`:
|
||||
|
||||
- [ ] Coverage test
|
||||
- [ ] Decode helper + 400 mapping
|
||||
- [ ] Proto cleanup
|
||||

# k6 Load Tests for Cart API
|
||||
|
||||
This directory contains a k6 script (`cart_load_test.js`) to stress and observe the cart actor HTTP API.
|
||||
|
||||
## Contents
|
||||
|
||||
- `cart_load_test.js` – primary k6 scenario script
|
||||
- `README.md` – this file
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Node not required (k6 runs standalone)
|
||||
- k6 installed (>= v0.43 recommended)
|
||||
- Prometheus + Grafana (optional) if you want to correlate with the dashboard you generated
|
||||
- A running cart service exposing HTTP endpoints at (default) `http://localhost:8080/cart`
|
||||
|
||||
## Endpoints Exercised
|
||||
|
||||
The script exercises (per iteration):
|
||||
|
||||
1. `GET /cart` – ensure / fetch cart state (creates cart if missing; sets `cartid` & `cartowner` cookies)
|
||||
2. `POST /cart` – add item mutation (random SKU & quantity)
|
||||
3. `GET /cart` – fetch after mutations
|
||||
4. `GET /checkout` – occasionally (~2% of iterations) to simulate checkout start
|
||||
|
||||
You can extend it easily to hit deliveries, quantity changes, or removal endpoints.
|
||||
|
||||
## Environment Variables
|
||||
|
||||
| Variable | Purpose | Default |
|
||||
|-----------------|----------------------------------------------|-------------------------|
|
||||
| `BASE_URL` | Base URL root (either host or host/cart) | `http://localhost:8080/cart` |
|
||||
| `VUS` | VUs for steady_mutations scenario | `20` |
|
||||
| `DURATION` | Duration for steady_mutations scenario | `5m` |
|
||||
| `RAMP_TARGET` | Peak VUs for ramp_up scenario | `50` |
|
||||
|
||||
You can also disable one scenario by editing `options.scenarios` inside the script.
|
||||
|
||||
Example run:
|
||||
|
||||
```bash
|
||||
k6 run \
|
||||
-e BASE_URL=https://cart.k6n.net/cart \
|
||||
-e VUS=40 \
|
||||
-e DURATION=1m \
|
||||
-e RAMP_TARGET=120 \
|
||||
k6/cart_load_test.js
|
||||
```
|
||||
|
||||
## Metrics (Custom)
|
||||
|
||||
The script defines additional k6 metrics:
|
||||
|
||||
- `cart_add_item_duration` (Trend) – latency of POST add item
|
||||
- `cart_fetch_duration` (Trend) – latency of GET cart state
|
||||
- `cart_checkout_duration` (Trend) – latency of checkout
|
||||
- `cart_items_added` (Counter) – successful add item operations
|
||||
- `cart_checkout_calls` (Counter) – successful checkout calls
|
||||
|
||||
Thresholds (in `options.thresholds`) enforce basic SLO:
|
||||
- Mutation failure rate < 2%
|
||||
- p90 mutation latency < 800 ms
|
||||
- p99 overall HTTP latency < 1500 ms
|
||||
|
||||
Adjust thresholds to your environment if they trigger prematurely.
|
||||
|
||||
## Cookies & Stickiness
|
||||
|
||||
The script preserves:
|
||||
- `cartid` – cart identity (server sets expiry separately)
|
||||
- `cartowner` – owning host for sticky routing
|
||||
|
||||
If your load balancer or ingress enforces affinity based on these cookies, traffic will naturally concentrate on the originally claimed host for each cart under test.
|
||||
|
||||
## SKU Set
|
||||
|
||||
SKUs used (randomly selected each mutation):
|
||||
|
||||
```
|
||||
778290 778345 778317 778277 778267 778376 778244 778384
|
||||
778365 778377 778255 778286 778246 778270 778266 778285
|
||||
778329 778425 778407 778418 778430 778469 778358 778351
|
||||
778319 778307 778278 778251 778253 778261 778263 778273
|
||||
778281 778294 778297 778302
|
||||
```
|
||||
|
||||
To add/remove SKUs, edit the `SKUS` array. Keeping it non-empty and moderately sized helps randomization.
|
||||
|
||||
## Extending the Script
|
||||
|
||||
### Add Quantity Change
|
||||
|
||||
```js
|
||||
function changeQuantity(itemId, newQty) {
|
||||
const payload = JSON.stringify({ Id: itemId, Qty: newQty });
|
||||
http.put(baseUrl() + '/', payload, { headers: headers() });
|
||||
}
|
||||
```
|
||||
|
||||
### Remove Item
|
||||
|
||||
```js
|
||||
function removeItem(itemId) {
|
||||
http.del(baseUrl() + '/' + itemId, null, { headers: headers() });
|
||||
}
|
||||
```
|
||||
|
||||
### Add Delivery
|
||||
|
||||
```js
|
||||
function addDelivery(itemIds) {
|
||||
const payload = JSON.stringify({ provider: "POSTNORD", items: itemIds });
|
||||
http.post(baseUrl() + '/delivery', payload, { headers: headers() });
|
||||
}
|
||||
```
|
||||
|
||||
You can integrate these into the iteration loop with probabilities.
|
||||
|
||||
## Output Summary
|
||||
|
||||
`handleSummary` outputs a JSON summary to stdout:
|
||||
- Average & p95 mutation latencies (if present)
|
||||
- Fetch p95
|
||||
- Checkout count
|
||||
- Check statuses
|
||||
|
||||
Redirect or parse that output for CI pipelines.
|
||||
|
||||
## Running in CI
|
||||
|
||||
Use shorter durations (e.g. `DURATION=2m VUS=10`) to keep builds fast. Fail build on threshold breaches:
|
||||
|
||||
```bash
|
||||
k6 run -e BASE_URL=$TARGET -e VUS=10 -e DURATION=2m k6/cart_load_test.js || exit 1
|
||||
```
|
||||
|
||||
## Correlating with Prometheus / Grafana
|
||||
|
||||
During load, observe:
|
||||
- `cart_mutations_total` growth and latency histograms
|
||||
- Event log write rate (`cart_event_log_appends_total`)
|
||||
- Pool usage (`cart_grain_pool_usage`) and spawn rate (`cart_grain_spawned_total`)
|
||||
- Failure counters (`cart_mutation_failures_total`) ensure they remain low
|
||||
|
||||
If mutation latency spikes without high error rate, inspect external dependencies (e.g., product fetcher or Klarna endpoints).
|
||||
|
||||
## Common Tuning Tips
|
||||
|
||||
| Symptom | Potential Adjustment |
|
||||
|------------------------------------|---------------------------------------------------|
|
||||
| High latency p99 | Increase CPU/memory, optimize mutation handlers |
|
||||
| Pool at capacity | Raise pool size argument or TTL |
|
||||
| Frequent cart eviction mid-test | Confirm TTL is sliding (now 2h on mutation) |
|
||||
| High replay duration | Consider snapshot + truncate event logs |
|
||||
| Uneven host load | Verify `cartowner` cookie is respected upstream |
|
||||
|
||||
## Safety / Load Guardrails
|
||||
|
||||
- Start with low VUs (5–10) and short duration.
|
||||
- Scale incrementally to find saturation points.
|
||||
- If using production endpoints, coordinate off-peak runs.

||||
