Deployment

ACOR is a library: you deploy your application, and it connects to Redis. Connection fields per topology are in Redis topologies — standalone for development and small workloads, Sentinel for failover, Cluster for horizontal scaling, Ring for client-side sharding.

Read credentials from the environment rather than the source:

ac, err := acor.Create(&acor.AhoCorasickArgs{
    Addr:     os.Getenv("REDIS_ADDR"),
    Password: os.Getenv("REDIS_PASSWORD"),
    Name:     "production",
})
if err != nil {
    panic(err)
}

Health endpoints

server/health belongs to the experimental acor/server module, versioned separately and not covered by the core compatibility promise. See Server.

health.RegisterHTTPHandlers(mux, checker) registers two Kubernetes-compatible routes:

Keep Redis reachability out of liveness: a Redis outage would fail every replica’s liveness probe at once, restart all of them, and repair nothing. It is a take me out of the load balancer signal.

The complete main — checker with its own deadline, mux composition, graceful shutdown — is Running a Server, which also explains why a readiness check built on Info() costs what the dictionary costs.

Checklist

1. Use the V2 schema for new collections (the default).
2. Set timeouts and pool size from measurements, not from guesses.
3. Monitor Redis memory and the cache counters.
4. Call Close() on shutdown.
