Release Notes

redis/go-redis (github.com/redis/go-redis/v9)

v9.22.0: 9.22.0

Compare Source

This is a minor release introducing two flagship (experimental) features — client-side caching and automatic pipelining — alongside support for Redis 8.10, new commands, and a large batch of stability and parser-robustness fixes. It consolidates everything shipped in 9.22.0-beta.1, so the notes below cover the full 9.21.0 → 9.22.0 upgrade.

⚠️ Two changes to be aware of when upgrading from 9.21.0:

• Default configuration values changed (#​3918): read/write timeouts, retry backoff, cluster state reload interval, and TCP keep-alive defaults are now aligned with the cross-SDK configuration proposal (see the highlight below). Explicitly configured values are unaffected.
• WaitAOF return type corrected (#​3888): WaitAOF now returns *IntSliceCmd, matching the two-integer reply of WAITAOF (previously *IntCmd, which failed to parse the reply at runtime). Code referencing the old return type needs a one-line update.

🚀 Highlights

Client-Side Caching (Experimental)

The standalone Client gains server-assisted client-side caching built on RESP3 CLIENT TRACKING. Enable it by setting ClientSideCacheConfig in Options (or supply your own cache via ClientSideCache — e.g. to share one cache across clients). Cacheable read results are served from a local in-process cache and invalidated automatically when the server reports a change, cutting round trips for read-heavy workloads.

The invalidation architecture is selected by ClientSideCacheStrategy; the default (and currently only) strategy is CSCStrategySharedTracking: one shared cache, every pool connection runs plain CLIENT TRACKING ON, and a background drainer applies buffered invalidations — portable (no BCAST) and consistent with the other Redis client libraries. Requirements and guardrails: RESP3 (Protocol: 3), standalone client, DB 0 only; commands that would change the connection identity (SELECT, AUTH, ...) are rejected while caching is enabled, and CSC is disabled when a credentials provider is set (fixed Username/Password work and are namespaced). See the README's client-side caching section and the runnable example.

Experimental: the API may change in a minor release.

Automatic Pipelining (Experimental)

AutoPipeliner is a background batcher that coalesces commands from many concurrent goroutines into Redis pipelines, multiplying throughput without any manual pipeline management. It comes in two faces, available on Client and ClusterClient (and configurable via Options.AutoPipelineOptions / UniversalOptions.AutoPipelineOptions):

• AutoPipeline() — the blocking face: a drop-in Cmdable where each call blocks until executed, exactly like a plain client, while concurrent callers' commands batch together under the hood (measured locally over loopback: ~1M+ SET/sec vs ~100k unpipelined; indicative, not a guarantee). Per-goroutine command order is preserved.
• AsyncAutoPipeline() — the deferred face: command calls return immediately and every typed result accessor (Val/Result/Err/...) blocks until the command has executed. Submit a window of commands, then read the results, to keep pipelines deep (~2–3M SET/sec locally; indicative).

AutoPipelineOptions controls batching: MaxBatchSize (soft target, default 200; the blocking face's preset uses 300), MaxBatchBytes (approximate payload cap so huge values flush as several bounded writes), MaxFlushDelay with optional AdaptiveDelay (delay scales down as the queue fills), and MaxConcurrentBatches (default 1 = a single ordered batch stream; raising it requires Unordered: true, so ordering is never lost by accident — Validate() rejects the combination otherwise). A usage tour and throughput comparison live in example/autopipeline.

Experimental: the API may change in a future release — pin your go-redis version if you adopt it.

Redis 8.10 Support

This release adds support for Redis 8.10. The README's supported-versions list now includes Redis 8.10, and CI runs the full suite against the redislabs/client-libs-test:8.10.0 image by default (#​3920, #​3940).

Coverage for the new commands and options that ship with Redis 8.10:

• HIMPORT (#​3919) — bulk hash import via server-side fieldsets, exposed as HImportPrepare, HImportSet, HImportDiscard, and HImportDiscardAll. Fieldsets are session state scoped to a single physical connection, which does not mix well with connection pooling — so the client keeps a versioned fieldset registry and lazily replays the PREPARE on whichever pooled connection executes a SET that needs it, at most once per connection, with no extra round trip (the PREPARE is injected into the same write as the SET).
• LMOVEM / BLMOVEM (#​3913) — move multiple elements between lists in one call.
• SUNIONCARD / SDIFFCARD (#​3897) — cardinality of set union/difference without materializing the result.
• XREAD / XREADGROUP MAXCOUNT and MAXSIZE (#​3898) — bound how much data a stream read returns.
• TS.READ (#​3896), TS.QUERYLABELS (#​3926), TS.NRANGE / TS.NREVRANGE (#​3870) with multiple aggregators per key (#​3937), and EXCLUDEEMPTY on TS.MRANGE / TS.MREVRANGE (#​3912) — new time-series query surface.
• FT.ALIASLIST (#​3925), COLLECT reducer for FT.AGGREGATE (#​3886), RERANK on HNSW vector fields in FT.CREATE (#​3927), and FT.HYBRID timeout warnings (#​3911) — search coverage.

Cross-SDK Aligned Defaults

Default configuration values now follow the cross-SDK configuration proposal shared by all Redis client libraries (#​3918):

Setting	Old default	New default
ReadTimeout / WriteTimeout	3s	5s
Retry backoff (min/max)	8ms / 512ms	10ms / 1s
Cluster state reload interval	10s	60s
TCP keep-alive	5min period	30s idle / 5s interval / 3 probes (net.KeepAliveConfig)

Applications that set these values explicitly are unaffected; applications relying on the old defaults inherit the new ones.

Data-Race and Parser Hardening Sweep

A systematic audit fixed data races across the client — hooks (AddHook, #​3868), Ring.SetAddrs (#​3862), cluster node slices (#​3861), pub/sub reconnect (#​3906), maintenance notifications (#​3894, #​3872), pool handoff (#​3876), and redisotel (#​3881) — and hardened the RESP parsers against malformed or unexpected replies: over-reads on nil replies (#​3874), integer overflow when skipping map/attribute bodies (#​3877), unhashable RESP3 map keys (#​3873), odd-length flat replies (#​3900), mismatched declared array lengths (#​3907), unexpected extra reply frames (#​3884), and nil elements in numeric/bool slice replies (#​3922).

PubSub Receive Hang Fix

PeekPushNotificationName blocked until 36 bytes were buffered, so a short subscribe confirmation (channel name of six or fewer characters) on an otherwise idle connection hung PubSub.Receive forever — a regression introduced in 9.20.1 by #​3842. The peek now parses whatever is already buffered and only waits for one more byte when the frame prefix is valid but incomplete. Fixes #​3935.

(#​3936) by @​ndyakov

Correct Cluster Transaction Retries

The cluster transaction pipeline treated a MULTI...EXEC block as independently retryable commands, which could scatter a transaction across nodes or send malformed transactions on retry. Redirects (MOVED/ASK/TRYAGAIN) and aborts are now handled at the whole-transaction level, matching Redis transaction semantics: the transaction is re-routed and retried as a unit, never partially (#​3909) by @​cxljs.

Credential Redaction in Command Tracing

rediscmd.AppendCmd — used by redisotel and rediscensus to render commands into span attributes — now redacts credential arguments as <redacted>: AUTH, HELLO ... AUTH, CONFIG SET of requirepass / masterauth / TLS key passphrases, ACL SETUSER password rules, and MIGRATE ... AUTH/AUTH2. The client sends HELLO ... AUTH on every handshake and AUTH on every streaming-credentials rotation through the regular hook chain, so tracing hooks previously captured credentials even when the application never issued an auth command itself (#​3939) by @​saddamr3e.

This is a patch release containing bug fixes only. There are no new features or breaking changes; upgrading from 9.20.0 is a drop-in replacement.

🚀 Highlights

RESP3 pub/sub message loss fixed

PeekPushNotificationName previously inspected only the bytes already buffered by bufio, so when a push frame header straddled a buffer fill boundary it could return a truncated notification name (e.g. "messa" instead of "message"). The push processor then mis-routed the frame and ReadReply silently dropped it, causing intermittent RESP3 pub/sub message loss. The peek now grows its window (36 bytes → up to 4 KiB) and reads more from the connection until the header is complete, cleanly separating incomplete prefixes from corrupt frames (including overflow-safe bulk-length handling). Fixes #​3839.

(#​3842) by @​ndyakov

🐛 Bug Fixes

• RESP3 push peeking: PeekPushNotificationName no longer returns a truncated notification name when a push frame header spans a buffer boundary, preventing silent RESP3 pub/sub message loss (fixes #​3839) (#​3842) by @​ndyakov
• FT.HYBRID vector params: Vector data is now always sent via PARAMS with auto-generated param names (__vector_param_N, with collision avoidance) when VectorParamName is omitted, since Redis no longer accepts inline vector blobs; the FTHybridOptions.Params map is no longer mutated, so the same options struct can be reused across calls (#​3844) by @​ndyakov
• CLUSTER SHARDS forward compatibility: Unknown shard- and node-level attributes in the CLUSTER SHARDS reply are now skipped via DiscardNext() instead of erroring, so clients keep working when the server introduces new fields (#​3843) by @​madolson
• PubSub double reconnect: PubSub.releaseConn no longer reconnects twice when a connection is both unusable (or pending handoff) and reports a bad-connection error, avoiding a wasted connection establish-then-close cycle (#​3833) by @​cxljs

Redis 8.8 Support

This release adds support for Redis 8.8. The README's supported-versions list now includes Redis 8.8 alongside 8.0/8.2/8.4, and CI exercises the 8.8 client-libs-test image across the full suite (Makefile, build workflow, doctests, run-tests action, and docker-compose).

Coverage for the new commands that ship in the 8.x line, rounded out in this release:

• AR* array data type (#​3813) — new array data structure, exposed via the ArrayCmdable interface (see the experimental-features highlight below).
• INCREX (#​3816) — atomic increment with expiration in a single round-trip.
• XNACK (#​3790) — explicit negative-acknowledge of pending stream entries.
• XAUTOCLAIM PEL deletes (#​3798) — XAUTOCLAIM/XAUTOCLAIMJUSTID now return the list of deleted message IDs from the pending entries list.
• TS.RANGE multiple aggregators (#​3791) — TS.RANGE/TS.REVRANGE/TS.MRANGE/TS.MREVRANGE accept multiple aggregators in a single call.
• Z(UNION|INTER|DIFF) COUNT aggregator (#​3802) — COUNT reducer for sorted-set set operations.
• JSON.SET FPHA (#​3797) — new FPHA argument that specifies the floating-point type for homogeneous FP arrays.

CI image bump (#​3814) by @​ofekshenawa. Command coverage contributions by @​cxljs, @​elena-kolevska, @​Khukharr, @​ndyakov, and @​ofekshenawa.

Stable RESP3 for RediSearch (UnstableResp3 deprecated)

FT.SEARCH, FT.AGGREGATE, FT.INFO, FT.SPELLCHECK, and FT.SYNDUMP now parse RESP3 (map) responses into the same typed result objects as RESP2 — Val() and Result() work uniformly on both protocols, no flag required. Previously, RESP3 search responses required UnstableResp3: true and were returned as opaque maps accessible only via RawResult() / RawVal().

As a result, the UnstableResp3 option is now a no-op across every options struct (Options, ClusterOptions, UniversalOptions, FailoverOptions, RingOptions) and has been marked // Deprecated:. The field is retained for backwards compatibility — existing code that sets UnstableResp3: true will continue to compile and behave identically — but it will be removed in a future release and new code should not set it. RawResult() / RawVal() continue to work for callers that prefer the raw RESP payload.

(#​3741) by @​ndyakov

Experimental Array Data Structure Commands

Adds an experimental ArrayCmdable interface with the AR* command family (ARSet, ARGet, ARGetRange, ARMSet, ARMGet, ARDel, ARDelRange, ARScan, ARSeek, ARNext, ARLastItems, ARGrep, ARGrepWithValues, ARInfo/ARInfoFull, and typed reducers AROpSum/AROpMin/AROpMax/AROpAnd/AROpOr/AROpXor/AROpMatch/AROpUsed) for working with Redis 8.8's new array data type. API is experimental and may change in a future release.

(#​3813) by @​cxljs

✨ New Features

• INCREX: New INCREX command support — atomic increment with expiration (#​3816) by @​ndyakov
• XNACK: Client support for the XNACK stream command for explicitly negative-acknowledging pending entries (#​3790) by @​elena-kolevska

🐛 Bug Fixes

• TLS-only Cluster PubSub: CLUSTER SLOTS port-0 entries now fall back to the origin endpoint's port, fixing dial tcp <ip>:0: connection refused on TLS-only clusters started with --port 0 --tls-port <port> (fixes #​3726) (#​3828) by @​ndyakov
• Sharded PubSub reconnect routing: PubSub.conn() now passes both regular (c.channels) and sharded (c.schannels) channels into the per-PubSub newConn closure. Previously, ClusterClient.SSubscribe-only PubSubs reconnected to a random node (because the routing closure saw an empty channel list), the SSUBSCRIBE was sent to the wrong shard, and the resulting MOVED reply was silently dropped (#​3829) by @​ndyakov
• ClusterClient Watch retry: User errors returned from a Watch callback are no longer subjected to cluster-retry classification; transient cluster errors still retry, but a callback returning e.g. net.ErrClosed short-circuits immediately (#​3821) by @​obiyang
• Sentinel concurrent-probe leak: MasterAddr's concurrent sentinel probe now closes the non-winning sentinel clients instead of leaking them (#​3827) by @​cxljs
• Sentinel rediscovery loop on master-only setups: replicaAddrs no longer tears down the cached sentinel client when the replica list is empty, eliminating a continuous rediscovery loop on master-only Sentinel deployments that flooded logs and added per-operation latency (#​3795) by @​shahyash2609
• Pool CloseConn hooks: Pool.CloseConn now triggers registered hooks, fixing a memory leak when connections are closed explicitly rather than via the normal removal path (#​3818) by @​ndyakov
• Dial TCP error redirection: Wrapped dial tcp errors are now correctly classified as redirectable so cluster routing can recover from a single unreachable node (#​3810) by @​vladisa88
• Pool Close health checks: ConnPool.Close now only runs health checks against idle connections, avoiding spurious activity on connections still in use (#​3805) by @​ndyakov
• VLinks return type: Fixed the return type of VLINKS/VLINKSWITHSCORES vector-set replies (#​3820) by @​romanpovol

🧪 Testing & Infrastructure

• Sentinel failover metric race: Fixed a data race in the sentinel failover metric test (#​3824) by @​cxljs
• waitForSentinelClusterStable post-conditions: The sentinel test harness now waits for replicas to be fully connected (not just present in the count) and is robust to randomized spec ordering after failover specs, eliminating an intermittent Expected master to equal slave flake (#​3830) by @​ndyakov
• govulncheck workflow: New scheduled GitHub Actions workflow runs govulncheck on every push, PR, and weekly, surfacing newly disclosed Go vulnerabilities even when no code changes (#​3779) by @​solardome
• CI Redis 8.8-rc1: CI now exercises the 8.8-rc1 Redis image (#​3814) by @​ofekshenawa

🧰 Maintenance

• Cmd.Slot() lookup refactor: Caches the per-command CommandInfo and short-circuits keyless commands before the switch dispatch, removing redundant Peek calls (#​3804) by @​retr0-kernel
• stdlib math/rand: Replaced internal/rand with math/rand from the standard library now that the minimum Go version is 1.24 (#​3823) by @​cxljs

🚀 Highlights

FIPS-Compatible Script Helper

Script now supports a FIPS-safe execution mode that avoids client-side SHA-1 computation, which is blocked in strict FIPS environments. A new NewScriptServerSHA constructor uses SCRIPT LOAD to obtain and cache the digest from the server, then runs commands via EVALSHA/EVALSHA_RO. Falls back to EVAL/EVALRO if loading fails, and transparently retries once on NOSCRIPT. The default behavior is unchanged for existing users.

(#​3700) by @​chaitanyabodlapati

FT.AGGREGATE Step-Based Pipeline Builder

Added a new step-based FT.AGGREGATE pipeline API via FTAggregateOptions.Steps, allowing LOAD, APPLY, GROUPBY, and SORTBY (with per-step MAX) to be repeated and interleaved in arbitrary order — matching Redis's native multi-stage aggregation semantics. The legacy Load/Apply/GroupBy/SortBy/SortByMax fields are now deprecated.

(#​3782) by @​ndyakov

Raw RESP Protocol Access

Added DoRaw and DoRawWriteTo methods for executing arbitrary commands and reading the raw RESP response. Useful for proxying, custom protocol inspection, and working with commands not yet wrapped by go-redis.

(#​3713) by @​ofekshenawa

Configurable Dial Retry Backoff

Added DialerRetryBackoff option (plumbed through Options, ClusterOptions, RingOptions, FailoverOptions) to let callers customize the delay between failed dial attempts. Helpers DialRetryBackoffConstant and DialRetryBackoffExponential (with jitter and cap) are provided out of the box. Dial timeout is now also applied per attempt rather than across all retries.

Full Changelog: redis/go-redis@v9.18.0...v9.19.0

v9.18.0: 9.18.0

Compare Source

Redis 8.6 Support

Added support for Redis 8.6, including new commands and features for streams idempotent production and HOTKEYS.

Smart Client Handoff (Maintenance Notifications) for Cluster

note: Pending RS version release

This release introduces comprehensive support for Redis Enterprise Cluster maintenance notifications via SMIGRATING/SMIGRATED push notifications. The client now automatically handles slot migrations by:

• Relaxing timeouts during migration (SMIGRATING) to prevent false failures
• Triggering lazy cluster state reloads upon completion (SMIGRATED)
• Enabling seamless operations during Redis Enterprise maintenance windows

(#​3643) by @​ndyakov

OpenTelemetry Native Metrics Support

Added comprehensive OpenTelemetry metrics support following the OpenTelemetry Database Client Semantic Conventions. The implementation uses a Bridge Pattern to keep the core library dependency-free while providing optional metrics instrumentation through the new extra/redisotel-native package.

Metric groups include:

• Command metrics: Operation duration with retry tracking
• Connection basic: Connection count and creation time
• Resiliency: Errors, handoffs, timeout relaxation
• Connection advanced: Wait time and use time
• Pubsub metrics: Published and received messages
• Stream metrics: Processing duration and maintenance notifications

(#​3637) by @​ofekshenawa

✨ New Features

• HOTKEYS Commands: Added support for Redis HOTKEYS feature for identifying hot keys based on CPU consumption and network utilization (#​3695) by @​ofekshenawa
• Streams Idempotent Production: Added support for Redis 8.6+ Streams Idempotent Production with ProducerID, IdempotentID, IdempotentAuto in XAddArgs and new XCFGSET command ([#​3693
