Operate Redis Streams

Redis carries audit, invalidation, revocation, agent, invocation, and delegation streams. It is correctness-critical, not an evictable cache.

Prerequisites

Use Streams, authentication, persistence, maxmemory-policy noeviction, and enough memory. The bundled image uses AOF with appendfsync everysec; validate external services separately.

Procedure

Provisioning is automatic in the bundled stack. From a checkout:

bash infra/redis/provision-streams.sh
bash infra/redis/scripts/verify.sh

Provide Redis host, port, and password file when needed. Monitor stream length, groups, pending entries, reclaim/retry, DLQ, memory, persistence, and latency.

Verify

Confirm expected streams/groups, idempotent provisioning, noeviction, persistence, and policy/revocation/audit delivery.

Recovery

Restore Redis, verify groups, then drain consumers and replay. Reconcile Postgres outboxes and replay directories. Never delete pending entries or reset groups until durable handling is proven.

Next Step

Use Scale Capacity when lag or memory grows.
