Release Notes

9.18.0-beta.2 (2025-12-09)

🚀 Highlights

Go Version Update

This release updates the minimum required Go version to 1.21. This is part of a gradual migration strategy where the minimum supported Go version will be three versions behind the latest release. With each new Go version release, we will bump the minimum version by one, ensuring compatibility while staying current with the Go ecosystem.

Stability Improvements

This release includes several important stability fixes:

• Fixed a critical panic in the handoff worker manager that could occur when handling nil errors
• Improved test reliability for Smart Client Handoff functionality
• Fixed logging format issues that could cause runtime errors

✨ New Features

• OpenTelemetry metrics improvements for nil response handling (#3638) by @fengve

🐛 Bug Fixes

• Fixed panic on nil error in handoffWorkerManager closeConnFromRequest (#3633) by @ccoVeille
• Fixed bad sprintf syntax in logging (#3632) by @ccoVeille

🧰 Maintenance

9.18.0-beta.1 (2025-12-01)

🚀 Highlights

Request and Response Policy Based Routing in Cluster Mode

This beta release introduces comprehensive support for KV COMMAND-based request and response policy routing for cluster clients. This feature enables intelligent command routing and response aggregation based on KV command metadata.

Key Features:

• Command Policy Loader: Automatically parses and caches COMMAND metadata with routing/aggregation hints
• Enhanced Routing Engine: Supports all request policies including:
  • default(keyless) - Commands without keys
  • default(hashslot) - Commands with hash slot routing
  • all_shards - Commands that need to run on all shards
  • all_nodes - Commands that need to run on all nodes
  • multi_shard - Commands that span multiple shards
  • special - Commands with custom routing logic
• Response Aggregator: Intelligently combines multi-shard replies based on response policies:
  • all_succeeded - All shards must succeed
  • one_succeeded - At least one shard must succeed
  • agg_sum - Aggregate numeric responses
  • special - Custom aggregation logic (e.g., FT.CURSOR)
• Raw Command Support: Policies are enforced on Client.Do(ctx, args...)

This feature is particularly useful for KV Stack commands like RediSearch that need to operate across multiple shards in a cluster.

Connection Pool Improvements

Fixed a critical defect in the connection pool's turn management mechanism that could lead to connection leaks under certain conditions. The fix ensures proper 1:1 correspondence between turns and connections.

✨ New Features

• Request and Response Policy Based Routing in Cluster Mode (#3422) by @ofekshenawa

🐛 Bug Fixes

• Fixed connection pool turn management to prevent connection leaks (#3626) by @cyningsun

9.12.1 (2025-08-11)

🚀 Highlights

In the last version (9.12.0) the client introduced bigger write and read buffer sized. The default value we set was 512KiB. However, users reported that this is too big for most use cases and can lead to high memory usage. In this version the default value is changed to 256KiB. The README.md was updated to reflect the correct default value and include a note that the default value can be changed.

Old Changelog

Unreleased

Changed

• go-kv won't skip span creation if the parent spans is not recording. (#2980) Users can use the OpenTelemetry sampler to control the sampling behavior. For instance, you can use the ParentBased(NeverSample()) sampler from go.opentelemetry.io/otel/sdk/trace to keep a similar behavior (drop orphan spans) of go-kv as before.

9.0.2 (2023-02-01)

Features

• upgrade OpenTelemetry, use the new metrics API. (#2410) (e29e42c)

v9 2023-01-30

Breaking

• Changed Pipelines to not be thread-safe any more.

Added

• Added support for RESP3 protocol. It was contributed by @monkey92t who has done the majority of work in this release.
• Added ContextTimeoutEnabled option that controls whether the client respects context timeouts and deadlines. See KV Timeouts for details.
• Added ParseClusterURL to parse URLs into ClusterOptions, for example, kv://user:password@localhost:6789?dial_timeout=3&read_timeout=6s&addr=localhost:6790&addr=localhost:6791.
• Added metrics instrumentation using kvotel.IstrumentMetrics. See documentation
• Added kv.HasErrorPrefix to help working with errors.

Changed

• Removed asynchronous cancellation based on the context timeout. It was racy in v8 and is completely gone in v9.
• Reworked hook interface and added DialHook.
• Replaced kvotel.NewTracingHook with kvotel.InstrumentTracing. See example and documentation.
• Replaced *kv.Z with kv.Z since it is small enough to be passed as value without making an allocation.
• Renamed the option MaxConnAge to ConnMaxLifetime.
• Renamed the option IdleTimeout to ConnMaxIdleTime.
• Removed connection reaper in favor of MaxIdleConns.
• Removed WithContext since context.Context can be passed directly as an arg.
• Removed Pipeline.Close since there is no real need to explicitly manage pipeline resources and it can be safely reused via sync.Pool etc. Pipeline.Discard is still available if you want to reset commands for some reason.

Fixed

• Improved and fixed pipeline retries.
• As usually, added support for more commands and fixed some bugs.
