Redis Deployment Checklist

Version: 1.1.0 | Updated: 2026-07-16

Purpose

Gate promotion and rollback of a Redis keyspace, cache, session store, rate limiter, stream consumer, or Redis topology.

Why

A syntactically valid Redis artifact can still fail because of maxmemory/OOM or unsafe eviction, WRONGTYPE or key-schema collision, MOVED/ASK cluster routing mismatch, READONLY/failover topology mismatch, slow command, big key, fork, persistence, or network latency. Promotion therefore requires target-state and rollback evidence.

How

Run against the exact target and immutable candidate. Preserve outputs from redis-cli -u <redacted-uri> INFO server; redis-cli -u <redacted-uri> INFO memory; redis-cli -u <redacted-uri> SLOWLOG GET 20; redis-cli -u <redacted-uri> LATENCY DOCTOR; redis-cli -u <redacted-uri> --latency from the application network. Stop promotion on any failed item.

Version-aware caution

Capture redis_version, mode, persistence, replication/cluster state, client library, and managed-service restrictions. Commands, ACLs, functions, eviction, and cluster behavior depend on server and client versions.

Tradeoffs

Promotion waits for "record Redis/client versions, cluster topology, memory headroom, fragmentation, persistence, replication, and failover state" and "estimate new key count, value size, TTL distribution, command complexity, and network bytes at peak". Those Redis target checks slow release but directly bound maxmemory/OOM or unsafe eviction and make this rollback executable: Disable writes to the new versioned key prefix and revert clients; let disposable keys expire or delete them with bounded SCAN/UNLINK jobs—never use FLUSHDB on a shared instance.

Anti-patterns

• Using unbounded values or KEYS on a shared production instance blocks Redis's command execution path and destabilizes unrelated tenants.
• Do not remove a native warning, validator, policy, or safety limit merely to make generated output pass.
• Do not claim a successful result without preserving the command, target, artifact/revision, and observed output.

Enterprise considerations

Redis governance allocates key prefixes, memory budgets, ACL patterns, persistence tiers, and noisy-neighbor controls; destructive commands require break-glass access.

Checklist

• record Redis/client versions, cluster topology, memory headroom, fragmentation, persistence, replication, and failover state.
• estimate new key count, value size, TTL distribution, command complexity, and network bytes at peak.
• load-test eviction, stampede, failover, reconnect, and source fallback behavior.
• ACL categories/key patterns grant the application only its required commands and prefixes.
• canary monitors used_memory, evictions, hit ratio, latency, blocked clients, replication, and errors.
• stream consumer groups, pending entries, and idempotency survive rolling consumer versions.
• rollback can read/delete the new key version without FLUSH* or broad scans.
• persistent uses prove backup/restore and replica promotion according to RPO/RTO.
• Disable writes to the new versioned key prefix and revert clients; let disposable keys expire or delete them with bounded SCAN/UNLINK jobs—never use FLUSHDB on a shared instance.
• Evidence identifies version, target, artifact/revision, command or manual method, UTC time, and result.

Changelog
