# Redis

> Wiki for Redis (OSS 8.x): data types, key expiration/eviction, pub/sub, transactions, scripting & Functions, the RESP protocol, client-side caching, redis-cli, persistence (RDB/AOF), and operations (replication, Sentinel, Cluster, ACL).
> Covers: Redis (OSS) 8.x: all core data types (strings/bitmaps/bitfields, lists, hashes, sets, sorted sets, streams, HyperLogLog, geospatial, JSON), key management and expiration/eviction policies, pub/sub, transactions (MULTI/EXEC/WATCH), programmability (Lua scripting + Functions), the RESP protocol, client-side caching, the redis-cli, persistence (RDB/AOF), and operations (replication, Sentinel, Cluster, ACL).
> Not covered: The exhaustive per-command reference, Redis Cloud/Enterprise, Redis Stack modules beyond JSON (Search/Query, Time Series), and client-library specifics — use redis.io. Current GA Redis 8.8; freshness = source fetch date below.
> Current as of: 2026-06-25 (8.8)
