Valkey is an open-source, high-performance key/value store (Redis fork). Used by Immich as a cache and job queue (BullMQ).

This is a lightweight component. Must be on the same Docker network as the Immich server.

Tuning (via Post Arguments):

• maxmemory 0 (unlimited). For low-memory systems, change to 256mb.
• appendonly yes. Enables job queue persistence across container restarts.
• tcp-keepalive 60. Faster dead connection detection in Docker networks (default: 300).

Storage sizing recommendations:

• Small (10k photos): 1-2GB
• Medium (10k-50k photos): 2-5GB
• Large (50k photos): 5-10GB

Note: Immich officially uses Valkey (not Redis) since their docker-compose.yml references valkey/valkey:9.

Must be on the same Docker network as the immich-server container. Full setup guide: https://rorar.github.io/immich-unraid-manual/
