# Changelog
|
|
|
|
## v8 (unreleased)
|
|
|
|
- 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 package variable `var ctx = context.TODO()` and use it
|
|
when `ctx` is expected.
|
|
- Ring uses Rendezvous Hashing by default which provides better distribution.
|
|
This means that existing keys must be moved to a new location or key 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)
|
|
},
|
|
})
|
|
```
|
|
|
|
- Basic support for OpenTelemetry instrumentation.
|
|
|
|
## 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
