Installation

go-redis requires a Go version with Modules support and uses import versioning. So please make sure to initialize a Go module before installing go-redis:

go mod init github.com/my/repo
go get github.com/antoinefinkelstein/redis/v7

Import:

import "github.com/antoinefinkelstein/redis/v7"

Quickstart

func ExampleNewClient() {
	client := redis.NewClient(&redis.Options{
		Addr:     "localhost:6379",
		Password: "", // no password set
		DB:       0,  // use default DB
	})

	pong, err := client.Ping().Result()
	fmt.Println(pong, err)
	// Output: PONG <nil>
}

func ExampleClient() {
	err := client.Set("key", "value", 0).Err()
	if err != nil {
		panic(err)
	}

	val, err := client.Get("key").Result()
	if err != nil {
		panic(err)
	}
	fmt.Println("key", val)

	val2, err := client.Get("key2").Result()
	if err == redis.Nil {
		fmt.Println("key2 does not exist")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2", val2)
	}
	// Output: key value
	// key2 does not exist
}

Howto

Please go through examples to get an idea how to use this package.

Look and feel

Some corner cases:

// SET key value EX 10 NX
set, err := client.SetNX("key", "value", 10*time.Second).Result()

// SORT list LIMIT 0 2 ASC
vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()

// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeBy{
	Min: "-inf",
	Max: "+inf",
	Offset: 0,
	Count: 2,
}).Result()

// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()

// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()

// custom command
res, err := client.Do("set", "key", "value").Result()

Overview

Package redis implements a Redis client.

Example (CustomCommand)
Get := func(rdb *redis.Client, key string) *redis.StringCmd {
	cmd := redis.NewStringCmd("get", key)
	rdb.Process(cmd)
	return cmd
}

v, err := Get(rdb, "key_does_not_exist").Result()
fmt.Printf("%q %s", v, err)
Output:

"" redis: nil
Example (CustomCommand2)
v, err := rdb.Do("get", "key_does_not_exist").String()
fmt.Printf("%q %s", v, err)
Output:

"" redis: nil
Example (Instrumentation)
rdb := redis.NewClient(&redis.Options{
	Addr: ":6379",
})
rdb.AddHook(redisHook{})

rdb.Ping()
Output:

starting processing: <ping: >
finished processing: <ping: PONG>

Example
err := rdb.Set("key", "value", 0).Err()
if err != nil {
	panic(err)
}

val, err := rdb.Get("key").Result()
if err != nil {
	panic(err)

func (Client) Set

func (c Client) Set(key string, value interface{}, expiration time.Duration) *StatusCmd

Redis `SET key value [expiration]` command.

Use expiration for `SETEX`-like behavior. Zero expiration means the key has no expiration time.

Example
// Last argument is expiration. Zero means the key has no
// expiration time.
err := rdb.Set("key", "value", 0).Err()
if err != nil {
	panic(err)
}

// key2 will expire in an hour.
err = rdb.Set("key2", "value", time.Hour).Err()
if err != nil {

func (c *Client) Subscribe(channels ...string) *PubSub

Subscribe subscribes the client to the specified channels. Channels can be omitted to create empty subscription. Note that this method does not wait on a response from Redis, so the subscription may not be active immediately. To force the connection to wait, you may call the Receive() method on the returned *PubSub like so:

sub := client.Subscribe(queryResp)
iface, err := sub.Receive()
if err != nil {
    // handle error
}

// Should be *Subscription, but others are possible if other actions have been
// taken on sub since it was created.
switch iface.(type) {
case *Subscription:
    // subscribe succeeded
case *Message:
    // received first message
case *Pong:
    // pong received
default:
    // handle error
}

pipe := rdb.TxPipeline()

incr := pipe.Incr("tx_pipeline_counter")
pipe.Expire("tx_pipeline_counter", time.Hour)

// Execute
//
//     MULTI
//     INCR pipeline_counter
//     EXPIRE pipeline_counts 3600
//     EXEC
//
// using one rdb-server roundtrip.

func (*Client) Watch

func (c *Client) Watch(fn func(*Tx) error, keys ...string) error

Watch prepares a transaction and marks the keys to be watched for conditional execution if there are any keys.

The transaction is automatically closed when fn exits.

Example
const routineCount = 100

// Transactionally increments key using GET and SET commands.
increment := func(key string) error {
	txf := func(tx *redis.Tx) error {
		// get current value or zero
		n, err := tx.Get(key).Int()
		if err != nil && err != redis.Nil {
			return err
		}

		// actual opperation (local in optimistic lock)
		n++

		// runs only if the watched keys remain unchanged
		_, err = tx.TxPipelined(func(pipe redis.Pipeliner) error {
			// pipe handles the error case
			pipe.Set(key, n, 0)
			return nil
		})
		return err
	}

	for retries := routineCount; retries > 0; retries-- {
		err := rdb.Watch(txf, key)
		if err != redis.TxFailedErr {
			return err
		}
		// optimistic lock lost
	}
	return errors.New("increment reached maximum number of retries")
}

var wg sync.WaitGroup
wg.Add(routineCount)
for i := 0; i < routineCount; i++ {
	go func() {
		defer wg.Done()

		if err := increment("counter3"); err != nil {
			fmt.Println("increment error:", err)
		}
	}()
}
wg.Wait()

n, err := rdb.Get("counter3").Int()
fmt.Println("ended with", n, err)
Output:

type Pipeliner

type Pipeliner interface {

	Process(cmd Cmder) error
	Close() error
	Discard() error
	Exec() ([]Cmder, error)
	ExecContext(ctx context.Context) ([]Cmder, error)
}

Pipeliner is an mechanism to realise Redis Pipeline technique.

Pipelining is a technique to extremely speed up processing by packing operations to batches, send them at once to Redis and read a replies in a singe step. See https://redis.io/topics/pipelining

Pay attention, that Pipeline is not a transaction, so you can get unexpected results in case of big pipelines and small read/write timeouts. Redis client has retransmission logic in case of timeouts, pipeline can be retransmitted and commands can be executed more then once. To avoid this: it is good idea to use reasonable bigger read/write timeouts depends of your batch size and/or use TxPipeline.

type Pong

type Pong struct {
	Payload string
}

Pong received as result of a PING command issued by another client.

func (*Pong) String

func (p *Pong) String() string

type PoolStats

type PoolStats pool.Stats

type PubSub

type PubSub struct {
	// contains filtered or unexported fields
}

PubSub implements Pub/Sub commands as described in http://redis.io/topics/pubsub. Message receiving is NOT safe for concurrent use by multiple goroutines.

PubSub automatically reconnects to Redis Server and resubscribes to the channels in case of network errors.

Example
pubsub := rdb.Subscribe("mychannel1")

// Wait for confirmation that subscription is created before publishing anything.
_, err := pubsub.Receive()
if err != nil {
	panic(err)
}

// Go channel which receives messages.
ch := pubsub.Channel()

// Publish a message.
err = rdb.Publish("mychannel1", "hello").Err()
if err != nil {
	panic(err)
}

time.AfterFunc(time.Second, func() {
	// When pubsub is closed channel is closed too.
	_ = pubsub.Close()
})

// Consume messages.
for msg := range ch {
	fmt.Println(msg.Channel, msg.Payload)
}
Output:

mychannel1 hello

func (*PubSub) Channel

func (c *PubSub) Channel() <-chan *Message

Channel returns a Go channel for concurrently receiving messages. The channel is closed together with the PubSub. If the Go channel is blocked full for 30 seconds the message is dropped. Receive* APIs can not be used after channel is created.

go-redis periodically sends ping messages to test connection health and re-subscribes if ping can not not received for 30 seconds.

func (*PubSub) ChannelSize

func (c *PubSub) ChannelSize(size int) <-chan *Message

ChannelSize is like Channel, but creates a Go channel with specified buffer size.

func (*PubSub) ChannelWithSubscriptions

func (c *PubSub) ChannelWithSubscriptions(size int) <-chan interface{}

ChannelWithSubscriptions is like Channel, but message type can be either *Subscription or *Message. Subscription messages can be used to detect reconnections.

ChannelWithSubscriptions can not be used together with Channel or ChannelSize.

func (*PubSub) Close

func (c *PubSub) Close() error

func (*PubSub) PSubscribe

func (c *PubSub) PSubscribe(patterns ...string) error

PSubscribe the client to the given patterns. It returns empty subscription if there are no patterns.

func (*PubSub) PUnsubscribe

func (c *PubSub) PUnsubscribe(patterns ...string) error

PUnsubscribe the client from the given patterns, or from all of them if none is given.

func (*PubSub) Ping

func (c *PubSub) Ping(payload ...string) error

func (*PubSub) Receive

func (c *PubSub) Receive() (interface{}, error)

Receive returns a message as a Subscription, Message, Pong or error. See PubSub example for details. This is low-level API and in most cases Channel should be used instead.

Example
pubsub := rdb.Subscribe("mychannel2")
defer pubsub.Close()

for i := 0; i < 2; i++ {
	// ReceiveTimeout is a low level API. Use ReceiveMessage instead.
	msgi, err := pubsub.ReceiveTimeout(time.Second)
	if err != nil {
		break
	}

	switch msg := msgi.(type) {
	case *redis.Subscription:
		fmt.Println("subscribed to", msg.Channel)

		_, err := rdb.Publish("mychannel2", "hello").Result()
		if err != nil {
			panic(err)
		}
	case *redis.Message:
		fmt.Println("received", msg.Payload, "from", msg.Channel)
	default:
		panic("unreached")
	}
}

// sent message to 1 rdb
// received hello from mychannel2

type Ring

type Ring struct {
	// contains filtered or unexported fields
}

Ring is a Redis client that uses consistent hashing to distribute keys across multiple Redis servers (shards). It's safe for concurrent use by multiple goroutines.

Ring monitors the state of each shard and removes dead shards from the ring. When a shard comes online it is added back to the ring. This gives you maximum availability and partition tolerance, but no consistency between different shards or even clients. Each client uses shards that are available to the client and does not do any coordination when shard state is changed.

Ring should be used when you need multiple Redis servers for caching and can tolerate losing data when one of the servers dies. Otherwise you should use Redis Cluster.

}

UniversalClient is an abstract client which - based on the provided options - can connect to either clusters, or sentinel-backed failover instances or simple single-instance servers. This can be useful for testing cluster-specific applications locally.

func NewUniversalClient

func NewUniversalClient(opts *UniversalOptions) UniversalClient

NewUniversalClient returns a new multi client. The type of client returned depends on the following three conditions:

1. if a MasterName is passed a sentinel-backed FailoverClient will be returned 2. if the number of Addrs is two or more, a ClusterClient will be returned 3. otherwise, a single-node redis Client will be returned.

Example (Cluster)
rdb := redis.NewUniversalClient(&redis.UniversalOptions{
	Addrs: []string{":7000", ":7001", ":7002", ":7003", ":7004", ":7005"},
})
defer rdb.Close()

rdb.Ping()
Output:

Example (Failover)
rdb := redis.NewUniversalClient(&redis.UniversalOptions{
	MasterName: "master",
	Addrs:      []string{":26379"},
})
defer rdb.Close()

rdb.Ping()
Output:

Example (Simple)
rdb := redis.NewUniversalClient(&redis.UniversalOptions{
	Addrs: []string{":6379"},
})
defer rdb.Close()

rdb.Ping()
Output:
