# [9.0.0-rc.2](https://github.com/go-redis/redis/compare/v9.0.0-rc.1...v9.0.0-rc.2) (2022-11-26) # Changelog
## v7.2
### Bug Fixes - Existing `HMSet` is renamed to `HSet` and old deprecated `HMSet` is restored for Redis 3 users.
* capture error correctly in withConn ([d1bfaba](https://github.com/go-redis/redis/commit/d1bfaba549fe380d269c26cea0a0183ed1520a85)) ## v7.1
* fixes ring.SetAddrs and rebalance race ([#2283](https://github.com/go-redis/redis/issues/2283)) ([d83436b](https://github.com/go-redis/redis/commit/d83436b321cd9ed52ba33c3edbe8f63bb0444c59))
* read in route_randomly query param correctly ([f236053](https://github.com/go-redis/redis/commit/f236053735d10aec5e6e31fc3ced1b2e53292554))
* reduce `SetAddrs` shards lock contention ([6c05a9f](https://github.com/go-redis/redis/commit/6c05a9f6b17f8e32593d3f7d594f82ba3dbcafb1)), closes [/github.com/go-redis/redis/pull/2190#discussion_r953040289](https://github.com//github.com/go-redis/redis/pull/2190/issues/discussion_r953040289) [#2077](https://github.com/go-redis/redis/issues/2077)
* wrap cmds in Conn.TxPipeline ([5053db2](https://github.com/go-redis/redis/commit/5053db2f9c8b3ca25f497a75f70012c7ad6cd775))
- Existing `Cmd.String` is renamed to `Cmd.Text`. New `Cmd.String` implements `fmt.Stringer` interface.
### Features ## v7
* add HasErrorPrefix ([d3d8002](https://github.com/go-redis/redis/commit/d3d8002e894a1eab5bab2c9fff13439527e330d8)) - *Important*. Tx.Pipeline now returns a non-transactional pipeline. Use Tx.TxPipeline for a transactional pipeline.
* add support for SINTERCARD command ([bc51c61](https://github.com/go-redis/redis/commit/bc51c61a458d1bc4fb4424c7c3e912325ef980cc)) - 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.
## v9 UNRELEASED ## 6.14
### Added - 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.
- Added support for [RESP3](https://github.com/antirez/RESP3/blob/master/spec.md) protocol. ## v6.13
Contributed by @monkey92t who has done a lot of work recently.
- Added `ContextTimeoutEnabled` option that controls whether the client respects context timeouts
and deadlines. See
[Redis Timeouts](https://redis.uptrace.dev/guide/go-redis-debugging.html#timeouts) for details.
- Added `ParseClusterURL` to parse URLs into `ClusterOptions`, for example,
`redis://user:password@localhost:6789?dial_timeout=3&read_timeout=6s&addr=localhost:6790&addr=localhost:6791`.
- Added metrics instrumentation using `redisotel.IstrumentMetrics`. See
[documentation](https://redis.uptrace.dev/guide/go-redis-monitoring.html)
### Changed - 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.
- Removed asynchronous cancellation based on the context timeout. It was racy in v8 and is ## v6.12
completely gone in v9.
- Reworked hook interface and added `DialHook`.
- Replaced `redisotel.NewTracingHook` with `redisotel.InstrumentTracing`. See
[example](example/otel) and
[documentation](https://redis.uptrace.dev/guide/go-redis-monitoring.html).
- Replaced `*redis.Z` with `redis.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 - 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
- Improved and fixed pipeline retries.
- As usual, added more commands and fixed some bugs.

## Installation ## Installation
go-redis supports 2 last Go versions and requires a Go version with go-redis requires a Go version with [Modules](https://github.com/golang/go/wiki/Modules) support and uses import versioning. So please make sure to initialize a Go module before installing go-redis:
[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
module:
```shell ``` shell
go mod init github.com/my/repo go mod init github.com/my/repo
go get github.com/go-redis/redis/v7
``` ```
If you are using **Redis 6**, install go-redis/**v8**: Import:
```shell ``` go
go get github.com/go-redis/redis/v8 import "github.com/go-redis/redis/v7"
```
If you are using **Redis 7**, install go-redis/**v9**:
```shell
go get github.com/go-redis/redis/v9
``` ```

## Run the test
go-redis will start a redis-server and run the test cases.
The paths of redis-server bin file and redis config file are defined in `main_test.go`:
```go
var (
redisServerBin, _ = filepath.Abs(filepath.Join("testdata", "redis", "src", "redis-server"))
redisServerConf, _ = filepath.Abs(filepath.Join("testdata", "redis", "redis.conf"))
)
```
For local testing, you can change the variables to refer to your local files, or create a soft link
to the corresponding folder for redis-server and copy the config file to `testdata/redis/`:
```shell
ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/
```
Lastly, run:
```shell
go test
``` ```

# Example for go-redis OpenTelemetry instrumentation
This example demonstrates how to monitor Redis using OpenTelemetry and
[Uptrace](https://github.com/uptrace/uptrace). It requires Docker to start Redis Server and Uptrace.
See
[Monitoring Go Redis Performance and Errors](https://redis.uptrace.dev/guide/go-redis-monitoring.html)
for details.
**Step 1**. Download the example using Git:
```shell
git clone https://github.com/go-redis/redis.git
cd example/otel
```
**Step 2**. Start the services using Docker:
```shell
docker-compose up -d
```
**Step 3**. Make sure Uptrace is running:
```shell
docker-compose logs uptrace
```
**Step 4**. Run the Redis client example and Follow the link to view the trace:
```shell
go run client.go
trace: http://localhost:14318/traces/ee029d8782242c8ed38b16d961093b35
```
![Redis trace](./image/redis-trace.png)
You can also open Uptrace UI at [http://localhost:14318](http://localhost:14318) to view available
spans, logs, and metrics.
## Redis monitoring
You can also [monitor Redis performance](https://uptrace.dev/opentelemetry/redis-monitoring.html)
metrics By installing OpenTelemetry Collector.
[OpenTelemetry Collector](https://uptrace.dev/opentelemetry/collector.html) is an agent that pulls
telemetry data from systems you want to monitor and sends it to APM tools using the OpenTelemetry
protocol (OTLP).
When telemetry data reaches Uptrace, it automatically generates a Redis dashboard from a pre-defined
template.
![Redis dashboard](./image/metrics.png)

# OpenTelemetry instrumentation for go-redis
## Installation
```bash
go get github.com/go-redis/redis/extra/redisotel/v9
```
## Usage
Tracing is enabled by adding a hook:
```go
import (
"github.com/go-redis/redis/v9"
"github.com/go-redis/redis/extra/redisotel/v9"
)
rdb := rdb.NewClient(&rdb.Options{...})
rdb.AddHook(redisotel.NewTracingHook())
```
See [example](example) and
[Monitoring Go Redis Performance and Errors](https://redis.uptrace.dev/guide/go-redis-monitoring.html)
for details.

# Prometheus Metric Collector
This package implements a [`prometheus.Collector`](https://pkg.go.dev/github.com/prometheus/client_golang@v1.12.2/prometheus#Collector)
for collecting metrics about the connection pool used by the various redis clients.
Supported clients are `redis.Client`, `redis.ClusterClient`, `redis.Ring` and `redis.UniversalClient`.
### Example
```go
client := redis.NewClient(options)
collector := redisprometheus.NewCollector(namespace, subsystem, client)
prometheus.MustRegister(collector)
```
### Metrics
| Name | Type | Description |
|---------------------------|----------------|-----------------------------------------------------------------------------|
| `pool_hit_total` | Counter metric | number of times a connection was found in the pool |
| `pool_miss_total` | Counter metric | number of times a connection was not found in the pool |
| `pool_timeout_total` | Counter metric | number of times a timeout occurred when getting a connection from the pool |
| `pool_conn_total_current` | Gauge metric | current number of connections in the pool |
| `pool_conn_idle_current` | Gauge metric | current number of idle connections in the pool |
| `pool_conn_stale_total` | Counter metric | number of times a connection was removed from the pool because it was stale |
