## 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.

## 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 |

## 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 |

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

// Compact CartID implementation using 64 bits of cryptographic randomness,
|
|
||||||
// base62 encoded (0-9 A-Z a-z). Typical length is 11 characters (since 62^11 > 2^64).
|
|
||||||
//
|
|
||||||
// Motivation:
|
|
||||||
// * Shorter identifiers for cookies / URLs than legacy padded 16-byte CartId
|
|
||||||
// * O(1) hashing (raw uint64) for consistent hashing ring integration
|
|
||||||
// * Extremely low collision probability (birthday bound negligible at scale)
|
|
||||||
//
|
|
||||||
// Backward Compatibility Strategy (Phased):
|
|
||||||
// Phase 1: Introduce CartID helpers while continuing to accept legacy CartId.
|
|
||||||
// Phase 2: Internally migrate maps to key by uint64 (CartID.Raw()).
|
|
||||||
// Phase 3: Canonicalize all inbound IDs to short base62; reissue Set-Cart-Id header.
|
|
||||||
//
|
|
||||||
// NOTE:
|
|
||||||
// The legacy type `CartId [16]byte` is still present elsewhere; helper
|
|
||||||
// UpgradeLegacyCartId bridges that representation to the new form without
|
|
||||||
// breaking deterministic mapping for existing carts.
|
|
||||||
//
|
|
||||||
// Security / Predictability:
|
|
||||||
// Uses crypto/rand for generation. If ever required, you can layer an
|
|
||||||
// HMAC-based derivation for additional secrecy. Current approach already
|
|
||||||
// provides 64 bits of entropy (brute force infeasible for practical risk).
|
|
||||||
//
|
|
||||||
// Future Extensions:
|
|
||||||
// * Time-sortable IDs: prepend a 48-bit timestamp field and encode 80 bits.
|
|
||||||
// * Add metrics counters for: generated_new, parsed_existing, legacy_fallback.
|
|
||||||
// * Add a pool of pre-generated IDs for ultra-low-latency hot paths (rarely needed).

// Mutation Registry Infrastructure
|
|
||||||
// --------------------------------
|
|
||||||
// This file introduces a generic registry for cart mutations that:
|
|
||||||
//
|
|
||||||
// 1. Decouples mutation logic from the large type-switch inside CartGrain.Apply.
|
|
||||||
// 2. Enforces (at registration time) that every mutation handler has the correct
|
|
||||||
// signature: func(*CartGrain, *T) error
|
|
||||||
// 3. Optionally auto-updates cart totals after a mutation if flagged.
|
|
||||||
// 4. Provides a single authoritative list of registered mutations for
|
|
||||||
// introspection / coverage testing.
|
|
||||||
// 5. Allows incremental migration: you can first register new mutations here,
|
|
||||||
// and later prune the legacy switch cases.
|
|
||||||
//
|
|
||||||
// Usage Pattern
|
|
||||||
// -------------
|
|
||||||
// // Define your mutation proto message (e.g. messages.ApplyCoupon in messages.proto)
|
|
||||||
// // Regenerate protobufs.
|
|
||||||
//
|
|
||||||
// // In an init() (ideally in a small file like mutations_apply_coupon.go)
|
|
||||||
// func init() {
|
|
||||||
// RegisterMutation[*messages.ApplyCoupon](
|
|
||||||
// "ApplyCoupon",
|
|
||||||
// func(g *CartGrain, m *messages.ApplyCoupon) error {
|
|
||||||
// // domain logic ...
|
|
||||||
// discount := int64(5000)
|
|
||||||
// if g.TotalPrice < discount {
|
|
||||||
// discount = g.TotalPrice
|
|
||||||
// }
|
|
||||||
// g.TotalDiscount += discount
|
|
||||||
// g.TotalPrice -= discount
|
|
||||||
// return nil
|
|
||||||
// },
|
|
||||||
// WithTotals(), // we changed price-related fields; recalc totals
|
|
||||||
// )
|
|
||||||
// }
|
|
||||||
//
|
|
||||||
// // To invoke dynamically (alternative to the current switch):
|
|
||||||
// if updated, err := ApplyRegistered(grain, incomingMessage); err == nil {
|
|
||||||
// grain = updated
|
|
||||||
// } else if errors.Is(err, ErrMutationNotRegistered) {
|
|
||||||
// // fallback to legacy switch logic
|
|
||||||
// }
|
|
||||||
//
|
|
||||||
// Migration Strategy
|
|
||||||
// ------------------
|
|
||||||
// 1. For each existing mutation handled in CartGrain.Apply, add a registry
|
|
||||||
// registration with equivalent logic.
|
|
||||||
// 2. Add a test that enumerates all *expected* mutation proto types and asserts
|
|
||||||
// they are present in RegisteredMutationTypes().
|
|
||||||
// 3. Once coverage is 100%, replace the switch in CartGrain.Apply with a call
|
|
||||||
// to ApplyRegistered (and optionally keep a minimal default to produce an
|
|
||||||
// "unsupported mutation" error).
|
|
||||||
//
|
|
||||||
// Thread Safety
|
|
||||||
// -------------
|
|
||||||
// Registration is typically done at init() time; a RWMutex provides safety
|
|
||||||
// should late dynamic registration ever be introduced.
|
|
||||||
//
|
|
||||||
// Auto Totals
|
|
||||||
// -----------
|
|
||||||
// Many mutations require recomputing totals. To avoid forgetting this, pass
|
|
||||||
// WithTotals() when registering. This will invoke grain.UpdateTotals() after
|
|
||||||
// the handler returns successfully.
|
|
||||||
//
|
|
||||||
// Error Semantics
|
|
||||||
// ---------------
|
|
||||||
// - If a handler returns an error, totals are NOT recalculated (even if
|
|
||||||
// WithTotals() was specified).
|
|
||||||
// - ApplyRegistered returns (nil, ErrMutationNotRegistered) if the message type
|
|
||||||
// is absent.
|
|
||||||
//
|
|
||||||
// Extensibility
|
|
||||||
// -------------
|
|
||||||
// It is straightforward to add options like audit hooks, metrics wrappers,
|
|
||||||
// or optimistic concurrency guards by extending MutationOption.
|
|
||||||
//
|
|
||||||
// NOTE: Generics require Go 1.18+. If constrained to earlier Go versions,
|
|
||||||
// replace the generic registration with a non-generic RegisterMutationType
|
|
||||||
// that accepts reflect.Type and an adapter function.

Integration Guide

|
||||||
-----------------
|
|
||||||
|
|
||||||
1. Register all existing mutations:
|
|
||||||
|
|
||||||
func init() {
|
|
||||||
RegisterMutation[*messages.AddItem]("AddItem",
|
|
||||||
func(g *CartGrain, m *messages.AddItem) error {
|
|
||||||
// (port logic from existing switch branch)
|
|
||||||
// ...
|
|
||||||
return nil
|
|
||||||
},
|
|
||||||
WithTotals(),
|
|
||||||
)
|
|
||||||
// ... repeat for others
|
|
||||||
}
|
|
||||||
|
|
||||||
2. In CartGrain.Apply (early in the method) add:
|
|
||||||
|
|
||||||
if updated, err := ApplyRegistered(c, content); err == nil {
|
|
||||||
return updated, nil
|
|
||||||
} else if err != ErrMutationNotRegistered {
|
|
||||||
return nil, err
|
|
||||||
}
|
|
||||||
|
|
||||||
// existing switch fallback below
|
|
||||||
|
|
||||||
3. Once all mutations are registered, remove the legacy switch cases
|
|
||||||
and leave a single ErrMutationNotRegistered path for unknown types.
|
|
||||||
|
|
||||||
4. Add a coverage test (see docs for example; removed from source for clarity).
|
|
||||||
5. (Optional) Add metrics / tracing wrappers for handlers.

// --------------------------------------------------------
|
|

// This file introduces a minimal, allocation‑light consistent hashing structure
|
|
||||||
// intended to replace per-cart ownership negotiation. It focuses on:
|
|
||||||
// * Deterministic lookup: O(log V) via binary search
|
|
||||||
// * Even(ish) distribution using virtual nodes (vnodes)
|
|
||||||
// * Epoch / fingerprint tracking to detect membership drift
|
|
||||||
//
|
|
||||||
// NOT YET WIRED:
|
|
||||||
// * SyncedPool integration (ownerForCart, lazy migration)
|
|
||||||
// * Replication factor > 1
|
|
||||||
// * Persistent state migration
|
|
||||||
//
|
|
||||||
// Safe to import now; unused until explicit integration code is added.
|
|
||||||
//
|
|
||||||
// Design Notes
|
|
||||||
// ------------
|
|
||||||
// - Hosts contribute `vnodesPerHost` virtual nodes. Higher counts smooth
|
|
||||||
// distribution at cost of memory (V = hosts * vnodesPerHost).
|
|
||||||
// - Hash of vnode = FNV1a64(host + "#" + index). For improved quality you
|
|
||||||
// can swap in xxhash or siphash later without changing API (but doing so
|
|
||||||
// will reshuffle ownership).
|
|
||||||
// - Cart ownership lookup uses either cartID.Raw() when provided (uniform
|
|
||||||
// 64-bit space) or falls back to hashing string forms (legacy).
|
|
||||||
// - Epoch is monotonically increasing; consumers can fence stale results.
|
|
||||||
//
|
|
||||||
// Future Extensions
|
|
||||||
// -----------------
|
|
||||||
// - Weighted hosts (proportionally more vnodes).
|
|
||||||
// - Replication: LookupN(h, n) to return primary + replicas.
|
|
||||||
// - Streaming / diff-based ring updates (gossip).
|
|
||||||
// - Hash function injection for deterministic test scenarios.
