# Changelog
|
|
|
|
> :heart: [**Uptrace.dev** - distributed traces, logs, and errors in one place](https://uptrace.dev)
|
|
|
|
## v8
|
|
|
|
- Documentation at https://redis.uptrace.dev/
|
|
|
|
- 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.
|
|
|
|
- Added `redis.NewFailoverClusterClient` that supports routing read-only commands to a slave node.
|
|
|
|
- Added `redisext.OpenTemetryHook` that adds
|
|
[Redis OpenTelemetry instrumentation](https://redis.uptrace.dev/tracing/).
|
|
|
|
- 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:
|
|
|
|
```go
|
|
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
