6.2.0

✨ Highlights

Cluster commands now follow the server's request/response policies. node-redis reads each command's routing policy from the server's COMMAND metadata and routes and aggregates accordingly, so the cluster client behaves much more like a single server. Multi-key commands that span hash slots — MGET, MSET, DEL, EXISTS, TOUCH, UNLINK — are transparently split per slot and their replies reassembled in caller order, so cross-slot calls that previously failed with CROSSSLOT now just work. Fan-out commands such as KEYS, DBSIZE, FLUSHALL, PING, WAIT, SCRIPT EXISTS and CONFIG SET run across every shard (or every node) and their replies are aggregated per the server's policy, SCAN walks the whole cluster behind a per-client virtual cursor, and RANDOMKEY / FT.CURSOR get correct cluster-aware routing. Replica read-scaling was also aligned with the server flags, so read-only keyless commands (DBSIZE, KEYS, SCAN, RANDOMKEY, and the RediSearch / time-series reads) can be served from replicas again.

⚠️ Behavior change for the raw sendCommand path: a table-recognized command sent raw — e.g. cluster.sendCommand(['DBSIZE']) — now follows its policy (fan-out and aggregate) instead of hitting a single node. Callers who relied on raw commands for per-node operations should target a specific node with cluster.nodeClient(node).sendCommand(...).

This release also brings a broad wave of new command coverage across the client and modules. The time-series package gains the most: new TS.NRANGE/TS.NREVRANGE multi-key pivot commands, a TS.READ cursor reader, TS.QUERYLABELS, EXCLUDEEMPTY on MRANGE/MREVRANGE, and multi-aggregator support. RediSearch adds FT.ALIASLIST, a COLLECT reducer for FT.AGGREGATE, HNSW RERANK, timeout warnings on the FT.SEARCH family, and the full set of stemmer languages. The core client adds SUNIONCARD/SDIFFCARD, LMOVEM/BLMOVEM, ZREVRANK WITHSCORE, COMMAND DOCS, and XREAD MAXCOUNT/MAXSIZE. A large batch of correctness fixes lands for zero-valued optional arguments (LIMIT 0, DB 0, SAMPLES 0, ENTRIESREAD 0, IDLETIME/FREQ 0, ENTRIESADDED 0) that were previously dropped from the wire, alongside several cluster and sentinel connection-lifecycle fixes.

The new HIMPORT command family (managed fieldset lifecycle) ships as experimental — see the warning below.
