8.11.4 (2021-10-04)

Features

• add acl auth support for sentinels (f66582f)
• add Cmd.{String,Int,Float,Bool}Slice helpers and an example (5d3d293)
• add SetVal method for each command (168981d)

v8.11

• Remove OpenTelemetry metrics.
• Supports more redis commands and options.

v8.10

• Removed extra OpenTelemetry spans from go-redis core. Now go-redis instrumentation only adds a single span with a Redis command (instead of 4 spans). There are multiple reasons behind this decision:

  • Traces become smaller and less noisy.
  • It may be costly to process those 3 extra spans for each query.
  • go-redis no longer depends on OpenTelemetry.

  Eventually we hope to replace the information that we no longer collect with OpenTelemetry Metrics.

v8.9

• Changed PubSub.Channel to only rely on Ping result. You can now use WithChannelSize, WithChannelHealthCheckInterval, and WithChannelSendTimeout to override default settings.

v8.8

• To make updating easier, extra modules now have the same version as go-redis does. That means that you need to update your imports:

github.com/go-redis/redis/extra/redisotel -> github.com/go-redis/redis/extra/redisotel/v8
github.com/go-redis/redis/extra/rediscensus -> github.com/go-redis/redis/extra/rediscensus/v8

v8.5

• knadh contributed long-awaited ability to scan Redis Hash into a struct:

err := rdb.HGetAll(ctx, "hash").Scan(&data)

err := rdb.MGet(ctx, "key1", "key2").Scan(&data)

• Please check redismock by monkey92t if you are looking for mocking Redis Client.

v8

• All commands require context.Context as a first argument, e.g. rdb.Ping(ctx). If you are not using context.Context yet, the simplest option is to define global package variable var ctx = context.TODO() and use it when ctx is required.

• Full support for context.Context canceling.

• Added redis.NewFailoverClusterClient that supports routing read-only commands to a slave node.

• Added redisext.OpenTemetryHook that adds Redis OpenTelemetry instrumentation.

• Redis slow log support.

• Ring uses Rendezvous Hashing by default which provides better distribution. You need to move existing keys to a new location or keys will be inaccessible / lost. To use old hashing scheme:

import "github.com/golang/groupcache/consistenthash"

ring := redis.NewRing(&redis.RingOptions{
    NewConsistentHash: func() {
        return consistenthash.New(100, crc32.ChecksumIEEE)
    },
})

• ClusterOptions.MaxRedirects default value is changed from 8 to 3.

• Options.MaxRetries default value is changed from 0 to 3.

• Cluster.ForEachNode is renamed to ForEachShard for consistency with Ring.

v7.3

• New option Options.Username which causes client to use AuthACL. Be aware if your connection URL contains username.

v7.2

• Existing HMSet is renamed to HSet and old deprecated HMSet is restored for Redis 3 users.

v7.1

• Existing Cmd.String is renamed to Cmd.Text. New Cmd.String implements fmt.Stringer interface.

v7

• Important. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a transactional pipeline.
• WrapProcess is replaced with more convenient AddHook that has access to context.Context.
• WithContext now can not be used to create a shallow copy of the client.
• New methods ProcessContext, DoContext, and ExecContext.
• Client respects Context.Deadline when setting net.Conn deadline.
• Client listens on Context.Done while waiting for a connection from the pool and returns an error when context context is cancelled.
• Add PubSub.ChannelWithSubscriptions that sends *Subscription in addition to *Message to allow detecting reconnections.
• time.Time is now marshalled in RFC3339 format. rdb.Get("foo").Time() helper is added to parse the time.
• SetLimiter is removed and added Options.Limiter instead.
• HMSet is deprecated as of Redis v4.

v6.15

• Cluster and Ring pipelines process commands for each node in its own goroutine.

6.14

• Added Options.MinIdleConns.
• Added Options.MaxConnAge.
• PoolStats.FreeConns is renamed to PoolStats.IdleConns.
• Add Client.Do to simplify creating custom commands.
• Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
• Lower memory usage.

v6.13

• Ring got new options called HashReplicas and Hash. It is recommended to set HashReplicas = 1000 for better keys distribution between shards.
• Cluster client was optimized to use much less memory when reloading cluster state.
• PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.
• Dialer.KeepAlive is set to 5 minutes by default.

v6.12

• ClusterClient got new option called ClusterSlots which allows to build cluster of normal Redis Servers that don’t have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup
