# Go Cart Actor
|
||||
|
||||
## Migration Notes (Ring-based Ownership Transition)
|
||||
|
||||
This release removes the legacy ConfirmOwner ownership negotiation RPC in favor of deterministic ownership via the consistent hashing ring.
|
||||
|
||||
Summary of changes:
|
||||
- ConfirmOwner RPC removed from the ControlPlane service.
|
||||
- OwnerChangeRequest message removed (was only used by ConfirmOwner).
|
||||
- OwnerChangeAck retained solely as the response type for the Closing RPC.
|
||||
- SyncedPool now relies exclusively on the ring for ownership (no quorum negotiation).
|
||||
- Remote proxy creation includes a bounded readiness retry to reduce first-call failures.
|
||||
- New Prometheus ring metrics:
|
||||
- cart_ring_epoch
|
||||
- cart_ring_hosts
|
||||
- cart_ring_vnodes
|
||||
- cart_ring_host_share{host}
|
||||
- cart_ring_lookup_local_total
|
||||
- cart_ring_lookup_remote_total
|
||||
|
||||
Action required for consumers:
|
||||
1. Regenerate protobuf code after pulling (requires protoc-gen-go and protoc-gen-go-grpc installed).
|
||||
2. Remove any client code or automation invoking ConfirmOwner (calls will now return UNIMPLEMENTED if using stale generated stubs).
|
||||
3. Update monitoring/alerts that referenced ConfirmOwner or ownership quorum failures—use ring metrics instead.
|
||||
4. If you previously interpreted “ownership flapping” via ConfirmOwner logs, now check for:
|
||||
- Rapid changes in ring epoch (cart_ring_epoch)
|
||||
- Host churn (cart_ring_hosts)
|
||||
- Imbalance in vnode distribution (cart_ring_host_share)
|
||||
|
||||
No data migration is necessary; cart IDs and grain state are unaffected.
|
||||
|
||||
---
|
||||
|
||||
A distributed cart management system using the actor model pattern.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Go 1.24.2+
|
||||
- Protocol Buffers compiler (`protoc`)
|
||||
- protoc-gen-go and protoc-gen-go-grpc plugins
|
||||
|
||||
### Installing Protocol Buffers
|
||||
|
||||
On Windows:
|
||||
```powershell
|
||||
winget install protobuf
|
||||
```
|
||||
|
||||
On macOS:
|
||||
```bash
|
||||
brew install protobuf
|
||||
```
|
||||
|
||||
On Linux:
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo apt install protobuf-compiler
|
||||
|
||||
# Or download from: https://github.com/protocolbuffers/protobuf/releases
|
||||
```
|
||||
|
||||
### Installing Go protobuf plugin
|
||||
|
||||
```bash
|
||||
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
|
||||
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
|
||||
```
|
||||
|
||||
## Working with Protocol Buffers
|
||||
|
||||
### Generating Go code from proto files
|
||||
|
||||
After modifying any proto (`proto/messages.proto`, `proto/cart_actor.proto`, `proto/control_plane.proto`), regenerate the Go code (all three share the unified `messages` package):
|
||||
|
||||
```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
|
||||
```
|
||||
|
||||
### Protocol Buffer Messages
|
||||
|
||||
The `proto/messages.proto` file defines the following message types:
|
||||
|
||||
- `AddRequest` - Add items to cart (includes quantity, sku, country, optional storeId)
|
||||
- `SetCartRequest` - Set entire cart contents
|
||||
- `AddItem` - Complete item information for cart
|
||||
- `RemoveItem` - Remove item from cart
|
||||
- `ChangeQuantity` - Update item quantity
|
||||
- `SetDelivery` - Configure delivery options
|
||||
- `SetPickupPoint` - Set pickup location
|
||||
- `PickupPoint` - Pickup point details
|
||||
- `RemoveDelivery` - Remove delivery option
|
||||
- `CreateCheckoutOrder` - Initiate checkout
|
||||
- `OrderCreated` - Order creation response
|
||||
|
||||
### Building the project
|
||||
|
||||
```bash
|
||||
go build .
|
||||
```
|
||||
|
||||
### Running tests
|
||||
|
||||
```bash
|
||||
go test ./...
|
||||
```
|
||||
|
||||
## HTTP API Quick Start (curl Examples)
|
||||
|
||||
Assuming the service is reachable at http://localhost:8080 and the cart API is mounted at /cart.
|
||||
Most endpoints use an HTTP cookie named `cartid` to track the cart. The first request will set it.
|
||||
|
||||
### 1. Get (or create) a cart
|
||||
```bash
|
||||
curl -i http://localhost:8080/cart/
|
||||
```
|
||||
Response sets a `cartid` cookie and returns the current (possibly empty) cart JSON.
|
||||
|
||||
### 2. Add an item by SKU (implicit quantity = 1)
|
||||
```bash
|
||||
curl -i --cookie-jar cookies.txt http://localhost:8080/cart/add/TEST-SKU-123
|
||||
```
|
||||
Stores cookie in `cookies.txt` for subsequent calls.
|
||||
|
||||
### 3. Add an item with explicit payload (country, quantity)
|
||||
```bash
|
||||
curl -i --cookie cookies.txt \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"sku":"TEST-SKU-456","quantity":2,"country":"se"}' \
|
||||
http://localhost:8080/cart/
|
||||
```
|
||||
|
||||
### 4. Change quantity of an existing line
|
||||
(First list the cart to find `id` of the line; here we use id=1 as an example)
|
||||
```bash
|
||||
curl -i --cookie cookies.txt \
|
||||
-X PUT -H "Content-Type: application/json" \
|
||||
-d '{"id":1,"quantity":3}' \
|
||||
http://localhost:8080/cart/
|
||||
```
|
||||
|
||||
### 5. Remove an item
|
||||
```bash
|
||||
curl -i --cookie cookies.txt -X DELETE http://localhost:8080/cart/1
|
||||
```
|
||||
|
||||
### 6. Set entire cart contents (overwrites items)
|
||||
```bash
|
||||
curl -i --cookie cookies.txt \
|
||||
-X POST -H "Content-Type: application/json" \
|
||||
-d '{"items":[{"sku":"TEST-SKU-AAA","quantity":1,"country":"se"},{"sku":"TEST-SKU-BBB","quantity":2,"country":"se"}]}' \
|
||||
http://localhost:8080/cart/set
|
||||
```
|
||||
|
||||
### 7. Add a delivery (provider + optional items)
|
||||
If `items` is empty or omitted, all items without a delivery get this one.
|
||||
```bash
|
||||
curl -i --cookie cookies.txt \
|
||||
-X POST -H "Content-Type: application/json" \
|
||||
-d '{"provider":"standard","items":[1,2]}' \
|
||||
http://localhost:8080/cart/delivery
|
||||
```
|
||||
|
||||
### 8. Remove a delivery by deliveryId
|
||||
```bash
|
||||
curl -i --cookie cookies.txt -X DELETE http://localhost:8080/cart/delivery/1
|
||||
```
|
||||
|
||||
### 9. Set a pickup point for a delivery
|
||||
```bash
|
||||
curl -i --cookie cookies.txt \
|
||||
-X PUT -H "Content-Type: application/json" \
|
||||
-d '{"id":"PUP123","name":"Locker 5","address":"Main St 1","city":"Stockholm","zip":"11122","country":"SE"}' \
|
||||
http://localhost:8080/cart/delivery/1/pickupPoint
|
||||
```
|
||||
|
||||
### 10. Checkout (returns HTML snippet from Klarna)
|
||||
```bash
|
||||
curl -i --cookie cookies.txt http://localhost:8080/cart/checkout
|
||||
```
|
||||
|
||||
### 11. Using a known cart id directly (bypassing cookie)
|
||||
If you already have a cart id (e.g. 1720000000000000):
|
||||
```bash
|
||||
CART_ID=1720000000000000
|
||||
curl -i http://localhost:8080/cart/byid/$CART_ID
|
||||
curl -i -X POST -H "Content-Type: application/json" \
|
||||
-d '{"sku":"TEST-SKU-XYZ","quantity":1,"country":"se"}' \
|
||||
http://localhost:8080/cart/byid/$CART_ID
|
||||
```
|
||||
|
||||
### 12. Clear cart cookie (forces a new cart on next request)
|
||||
```bash
|
||||
curl -i --cookie cookies.txt -X DELETE http://localhost:8080/cart/
|
||||
```
|
||||
|
||||
Tip: Use `--cookie-jar` and `--cookie` to persist the session across multiple commands:
|
||||
```bash
|
||||
curl --cookie-jar cookies.txt http://localhost:8080/cart/
|
||||
curl --cookie cookies.txt http://localhost:8080/cart/add/TEST-SKU-123
|
||||
```
|
||||
|
||||
## Important Notes
|
||||
|
||||
- Always regenerate protobuf Go code after modifying any `.proto` files (messages/cart_actor/control_plane)
|
||||
- The generated `messages.pb.go` file should not be edited manually
|
||||
- Make sure your PATH includes the protoc-gen-go binary location (usually `$GOPATH/bin`)
|
||||
|
||||

|
||||
|
||||
## 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
|

|
||||
|
||||
## 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 |

|
||||
|
||||
---
|
||||
|
||||
## 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
|
||||
- [ ] Registry metrics instrumentation
|
||||
- [ ] Ownership multi-node test
|
||||
- [ ] Lease versioning
|
||||
- [ ] Delivery pricing abstraction
|
||||
- [ ] TLS/mTLS internal
|
||||
- [ ] BatchMutate design doc
|
||||

# 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 /cart/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.prod.example.com/cart \
|
||||
-e VUS=40 \
|
||||
-e DURATION=10m \
|
||||
-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.

Package voucher - rule parser
|
||||
|
||||
A lightweight parser for voucher rule expressions.
|
||||
|
||||
Supported rule kinds (case-insensitive keywords):
|
||||
|
||||
sku=SKU1|SKU2|SKU3
|
||||
- At least one of the listed SKUs must be present in the cart.
|
||||
|
||||
category=CatA|CatB|CatC
|
||||
- At least one of the listed categories must be present.
|
||||
|
||||
min_total>=12345
|
||||
- Cart total (Inc VAT) must be at least this value (int64).
|
||||
|
||||
min_item_price>=5000
|
||||
- At least one individual item (Inc VAT single unit price) must be at least this value (int64).
|
||||
|
||||
Rule list grammar (simplified):
|
||||
rules := rule (sep rule)*
|
||||
rule := (sku|category) '=' valueList
|
||||
| (min_total|min_item_price) comparator number
|
||||
valueList := value ('|' value)*
|
||||
comparator := '>=' (only comparator currently supported for numeric rules)
|
||||
sep := ';' | ',' | newline
|
||||
|
||||
Whitespace is ignored around tokens.
|
||||
|
||||
Example:
|
||||
sku=ABC123|XYZ999; category=Shoes|Bags
|
||||
min_total>=10000
|
||||
min_item_price>=2500, category=Accessories
|
||||
|
||||
Parsing returns a RuleSet which can later be evaluated against a generic context.
|
||||
The evaluation context uses simple Item abstractions to avoid tight coupling with
|
||||
the cart implementation (which currently lives under cmd/cart and cannot be
|
||||
imported due to being in package main).
|
||||
|
||||
This is intentionally conservative and extensible:
|
||||
* Adding new rule kinds: extend RuleKind constants, add parse + evaluate logic.
|
||||
* Supporting new operators: extend numeric rule parsing & evaluation.
