Every site (`ftest`, `f18-dev`, production, etc.) runs its own independent Valkey cluster. All services on a site point at that site's cluster. + +This spec covers the code changes required to make `pkg/roomkeystore` and `pkg/valkeyutil` work against a Valkey cluster, the service-level config changes to switch from a single address to a cluster address list, and the per-site docker-compose changes to run a cluster instead of a single node. + +--- + +## Motivation + +Room encryption keys stored in `pkg/roomkeystore` are critical data. If the single Valkey node goes down and restarts without restoring its data, every room on that site loses its key — subsequent `broadcast-worker` encryptions fail and clients cannot decrypt messages until keys are regenerated out of band. A Valkey cluster tolerates individual node failures without data loss, eliminating this operational risk. + +The search subscription cache (`search-service` via `pkg/valkeyutil`) is less critical — it is ephemeral and rebuilds on cache miss — but running it on the same cluster keeps the infrastructure uniform across services and sites. + +--- + +## Architecture + +Each site runs **one Valkey cluster** shared by all services on that site. The cluster has a minimum of 3 master nodes (the Valkey cluster protocol requires at least 3 masters to elect a new primary after a failure). Replicas per master are a deployment decision; 0 replicas is acceptable for non-production sites. + +``` +site: ftest + ├── valkey-cluster (3 masters, 0 replicas) + │ node-1:6379 + │ node-2:6380 + │ node-3:6381 + ├── room-service → VALKEY_ADDRS=node-1:6379,node-2:6380,node-3:6381 + ├── room-worker → VALKEY_ADDRS=node-1:6379,node-2:6380,node-3:6381 + ├── broadcast-worker → VALKEY_ADDRS=node-1:6379,node-2:6380,node-3:6381 + ├── history-service → VALKEY_ADDRS=node-1:6379,node-2:6380,node-3:6381 + └── search-service → VALKEY_ADDRS=node-1:6379,node-2:6380,node-3:6381 +``` + +Sites are fully independent — no cross-site Valkey connection exists or is introduced by this spec. + +--- + +## Change 1: Key Name Hash Tags — `pkg/roomkeystore` + +### The Problem + +The Lua rotate script in `adapter.go` operates on two keys per room in a single atomic call: + +``` +room:abc123:key +room:abc123:key:prev +``` + +In Valkey cluster mode, every key is assigned to one of 16384 slots based on a CRC16 hash of the key name. A Lua script that touches keys on different slots is rejected with `CROSSSLOT`. Without hash tags, `room:abc123:key` and `room:abc123:key:prev` hash to different slots. + +The `deletePipeline` also issues a single `DEL` on both keys — same constraint applies. + +### The Fix + +Add a hash tag `{roomID}` to both key names. Valkey uses only the substring inside `{...}` for slot assignment, so both keys for the same room always land on the same slot regardless of the `roomID` value. + +```go +// Current +func roomkey(roomID string) string { return "room:" + roomID + ":key" } +func roomprevkey(roomID string) string { return "room:" + roomID + ":key:prev" } + +// After +func roomkey(roomID string) string { return "room:{" + roomID + "}:key" } +func roomprevkey(roomID string) string { return "room:{" + roomID + "}:key:prev" } +``` + +### Migration Impact + +This is a **breaking change for any existing Valkey data**. Keys written under the old format (`room:abc123:key`) are not found after this change because the key name is different. Services will behave as if no key exists for that room — `keyStore.Get` returns `(nil, nil)`. + +Rollout assumption for this spec: **all sites deploying cluster mode start with a fresh Valkey cluster**. No migration of old standalone keys is required. Rooms that were created before this change will have their keys regenerated the next time a member-remove triggers rotation, or via the existing `ErrNoCurrentKey` → `Set` fallback in `room-service`. + +Production sites upgrading from standalone to cluster must account for this: either accept a key-loss window (rooms enter degraded state until next operation triggers regeneration) or run a backfill tool before switching. Backfill tooling is out of scope for this spec. + +--- + +## Change 2: Cluster Adapter — `pkg/roomkeystore` + +### `ClusterConfig` + +A new config struct alongside the existing `Config`: + +```go +// ClusterConfig holds connection config for a Valkey cluster deployment. +// Addrs is a comma-separated list of seed node addresses; the go-redis +// ClusterClient discovers all nodes automatically via CLUSTER SLOTS. +// One address is sufficient but listing all masters is more robust. +type ClusterConfig struct { + Addrs []string `env:"VALKEY_ADDRS,required" envSeparator:","` + Password string `env:"VALKEY_PASSWORD" envDefault:""` + GracePeriod time.Duration `env:"VALKEY_KEY_GRACE_PERIOD,required"` +} +``` + +The existing `Config` (single `Addr string`) is retained unchanged for standalone deployments. + +### `clusterAdapter` + +A new adapter wrapping `*redis.ClusterClient` that satisfies the existing `hashCommander` interface: + +```go +type clusterAdapter struct { + c *redis.ClusterClient +} +``` + +All method signatures are identical to `redisAdapter`. `redis.ClusterClient` exposes the same command API as `redis.Client` (`HSet`, `HGetAll`, `Del`, `Pipeline`, `NewScript().Run`) so the implementation is a direct parallel — the only difference is the underlying client type. + +The Lua `rotateScript` is registered the same way via `redis.NewScript` and executes correctly on `ClusterClient` as long as both keys are hash-tagged to the same slot (guaranteed by Change 1). + +### `NewValkeyClusterStore` + +```go +func NewValkeyClusterStore(cfg ClusterConfig) (RoomKeyStore, error) { + c := redis.NewClusterClient(&redis.ClusterOptions{ + Addrs: cfg.Addrs, + Password: cfg.Password, + }) + ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second) + defer cancel() + if err := c.Ping(ctx).Err(); err != nil { + return nil, fmt.Errorf("valkey cluster connect: %w", err) + } + return &valkeyStore{ + client: &clusterAdapter{c: c}, + closer: c, + gracePeriod: cfg.GracePeriod, + }, nil +} +``` + +`valkeyStore` and all its methods (`Set`, `Get`, `GetMany`, `GetByVersion`, `Rotate`, `Delete`, `SetWithVersion`, `Close`) are **unchanged**. The cluster is entirely transparent at the `valkeyStore` level. + +### `GetMany` pipeline in cluster mode + +`hgetallMany` issues a pipeline of `HGETALL` commands. `go-redis` `ClusterClient` handles cross-slot pipelines automatically — it groups commands by slot and issues separate round-trips to each node in parallel, then reassembles results in order. Because each `HGETALL room:{roomID}:key` touches only one key per room, this works correctly in cluster mode without any code change to `hgetallMany`. + +--- + +## Change 3: `pkg/valkeyutil` Cluster Support + +`search-service` connects via `valkeyutil.Connect` which uses `redis.NewClient` (standalone only). A parallel `ConnectCluster` function is added: + +```go +func ConnectCluster(ctx context.Context, addrs []string, password string) (Client, error) { + c := redis.NewClusterClient(&redis.ClusterOptions{ + Addrs: addrs, + Password: password, + }) + pingCtx, cancel := context.WithTimeout(ctx, 5*time.Second) + defer cancel() + if err := c.Ping(pingCtx).Err(); err != nil { + if closeErr := c.Close(); closeErr != nil { + slog.Warn("valkey cluster close after failed connect", "error", closeErr) + } + return nil, fmt.Errorf("valkey cluster connect: %w", err) + } + slog.Info("connected to Valkey cluster", "addrs", addrs) + return &redisClient{c: c.(*redis.Client)}, nil +} +``` + +Wait — `redis.ClusterClient` and `redis.Client` are different types. The existing `redisClient` wrapper in `valkeyutil` wraps `*redis.Client`. A second wrapper `clusterRedisClient` is introduced for `*redis.ClusterClient`, satisfying the same `Client` interface. Both wrappers implement `Get`, `Set`, `Del`, `Close`. + +The existing `Connect` (standalone) is retained unchanged. + +--- + +## Change 4: Service Config Changes + +Each service switches from `VALKEY_ADDR` (single address) to `VALKEY_ADDRS` (comma-separated list). The `env` tag uses `envSeparator:","` to parse into `[]string`. Services call `NewValkeyClusterStore` instead of `NewValkeyStore`. + +| Service | Config field change | Constructor change | +|---|---|---| +| `room-service` | `ValkeyAddr string` → `ValkeyAddrs []string` | `NewValkeyStore` → `NewValkeyClusterStore` | +| `room-worker` | `ValkeyAddr string` → `ValkeyAddrs []string` | `NewValkeyStore` → `NewValkeyClusterStore` | +| `broadcast-worker` | `ValkeyAddr string` → `ValkeyAddrs []string` | `NewValkeyStore` → `NewValkeyClusterStore` | +| `history-service` | `ValkeyAddr string` → `ValkeyAddrs []string` | `NewValkeyStore` → `NewValkeyClusterStore` | +| `search-service` | `Valkey.Addr string` → `Valkey.Addrs []string` | `valkeyutil.Connect` → `valkeyutil.ConnectCluster` | + +Validation: services that currently fail-fast on empty `VALKEY_ADDR` now fail-fast on empty `VALKEY_ADDRS` (zero-length slice). + +--- + +## Change 5: Per-Site Docker Compose + +Each service's `deploy/docker-compose.yml` currently declares a single Valkey node.

fix ping-failure leaks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace redisAdapter+clusterAdapter with a single universalAdapter in pkg/roomkeystore — both *redis.Client and *redis.ClusterClient implement redis.UniversalClient, eliminating ~70 lines of duplicated method bodies - Replace redisClient+clusterRedisClient with universalClient in pkg/valkeyutil for the same reason - NewValkeyStore now closes the client on ping failure (matches the existing behaviour in Connect/ConnectCluster and prevents pool leaks) - Remove dead env struct tags from ClusterConfig (fields are populated directly by callers, never via caarlos0/env) - Drop redundant comment on roomprevkey (function name is self-explanatory)
