Overview

Package redis implements a Redis client.

Example (CustomCommand) 
package main

import (
	"fmt"

	"github.com/go-redis/redis"
)

var client *redis.Client

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

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

Output:

"" redis: nil
Example (Instrumentation) 
package main

import (
	"fmt"
	"sync/atomic"
	"time"

	"github.com/go-redis/redis"
)

func main() {
	ring := redis.NewRing(&redis.RingOptions{
		Addrs: map[string]string{
			"shard1": ":6379",
		},
	})
	ring.ForEachShard(func(client *redis.Client) error {
		wrapRedisProcess(client)
		return nil
	})

	for {
		ring.Ping()
	}
}

func wrapRedisProcess(client *redis.Client) {
	const precision = time.Microsecond
	var count, avgDur uint32

	go func() {
		for range time.Tick(3 * time.Second) {
			n := atomic.LoadUint32(&count)
			dur := time.Duration(atomic.LoadUint32(&avgDur)) * precision
			fmt.Printf("%s: processed=%d avg_dur=%s\n", client, n, dur)
		}
	}()

	client.WrapProcess(func(oldProcess func(redis.Cmder) error) func(redis.Cmder) error {
		return func(cmd redis.Cmder) error {
			start := time.Now()
			err := oldProcess(cmd)
			dur := time.Since(start)

			const decay = float64(1) / 100
			ms := float64(dur / precision)
			for {
				avg := atomic.LoadUint32(&avgDur)
				newAvg := uint32((1-decay)*float64(avg) + decay*ms)
				if atomic.CompareAndSwapUint32(&avgDur, avg, newAvg) {
					break
				}
			}
			atomic.AddUint32(&count, 1)

			return err
		}
	})
}

Output:

Client is a Redis client representing a pool of zero or more underlying connections. It's safe for concurrent use by multiple goroutines.

Example 
package main

import (
	"fmt"

	"github.com/go-redis/redis"
)

var client *redis.Client

func main() {
	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:

key2 does not exist

func NewClient 

func NewClient(opt *Options) *Client

NewClient returns a client to the Redis Server specified by Options.

		Password: "", // no password set
		DB:       0,  // use default DB
	})

	pong, err := client.Ping().Result()
	fmt.Println(pong, err)
}

Output:

PONG <nil>

func NewFailoverClient 

func NewFailoverClient(failoverOpt *FailoverOptions) *Client

NewFailoverClient returns a Redis client that uses Redis Sentinel for automatic failover. It's safe for concurrent use by multiple goroutines.

Example 
package main

import (
	"github.com/go-redis/redis"
)

func main() {
	// See http://redis.io/topics/sentinel for instructions how to
	// setup Redis Sentinel.
	client := redis.NewFailoverClient(&redis.FailoverOptions{
		MasterName:    "master",
		SentinelAddrs: []string{":26379"},
	})
	client.Ping()
}

Output:

var client *redis.Client

func main() {
	if err := client.RPush("queue", "message").Err(); err != nil {
		panic(err)

	if err != nil {
		panic(err)
	}
	fmt.Println(subscr)

	err = client.Publish("mychannel1", "hello").Err()

package main

import (
	"fmt"
	"time"

	"github.com/go-redis/redis"
)

var client *redis.Client

func main() {
	pubsub := client.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 := client.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 client
	// received hello from mychannel2
}

Output:

func (*PubSub) ReceiveMessage

ReceiveMessage returns a Message or error ignoring Subscription or Pong messages. It automatically reconnects to Redis Server and resubscribes to channels in case of network errors.

func (*PubSub) ReceiveTimeout 

func (c *PubSub) ReceiveTimeout(timeout time.Duration) (interface{}, error)

ReceiveTimeout acts like Receive but returns an error if message is not received in time. This is low-level API and most clients should use ReceiveMessage.

func (*PubSub) Subscribe

Subscribes the client to the specified channels. It returns empty subscription if there are no channels.

func (*PubSub) Unsubscribe 

func (c *PubSub) Unsubscribe(channels ...string) error

Unsubscribes the client from the given channels, or from all of them if none is given.

type Ring 

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

Ring is a Redis client that uses constistent 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 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.

func NewRing 

func NewRing(opt *RingOptions) *Ring
Example 
package main

import (
	"github.com/go-redis/redis"
)

func main() {
	client := redis.NewRing(&redis.RingOptions{
		Addrs: map[string]string{
			"shard1": ":7000",

type Tx 

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

Tx implements Redis transactions as described in http://redis.io/topics/transactions. It's NOT safe for concurrent use by multiple goroutines, because Exec resets list of watched keys. If you don't need WATCH it is better to use Pipeline.

func (*Tx) Auth 

func (c *Tx) Auth(password string) *StatusCmd

func (*Tx) ClientSetName 

func (c *Tx) ClientSetName(name string) *BoolCmd

ClientSetName assigns a name to the connection.

func (*Tx) Close 

func (c *Tx) Close() error

close closes the transaction, releasing any open resources.

func (*Tx) Pipeline 

func (c *Tx) Pipeline() Pipeliner

func (*Tx) Pipelined 

func (c *Tx) Pipelined(fn func(Pipeliner) error) ([]Cmder, error)

Pipelined executes commands queued in the fn in a transaction and restores the connection state to normal.

When using WATCH, EXEC will execute commands only if the watched keys were not modified, allowing for a check-and-set mechanism.

Exec always returns list of commands. If transaction fails TxFailedErr is returned. Otherwise Exec returns error of the first failed command or nil.

func (*Tx) Process 

func (c *Tx) Process(cmd Cmder) error

func (*Tx) ReadOnly 

func (c *Tx) ReadOnly() *StatusCmd

func (*Tx) ReadWrite

func (*Tx) String 

func (c *Tx) String() string

func (*Tx) TxPipeline 

func (c *Tx) TxPipeline() Pipeliner

func (*Tx) TxPipelined 

func (c *Tx) TxPipelined(fn func(Pipeliner) error) ([]Cmder, error)

func (*Tx) Unwatch 

func (c *Tx) Unwatch(keys ...string) *StatusCmd

Unwatch flushes all the previously watched keys for a transaction.

func (*Tx) Watch 

func (c *Tx) Watch(keys ...string) *StatusCmd

Watch marks the keys to be watched for conditional execution of a transaction.

func (*Tx) WrapProcess 

func (c *Tx) WrapProcess(fn func(oldProcess func(cmd Cmder) error) func(cmd Cmder) error)

WrapProcess replaces the process func. It takes a function createWrapper which is supplied by the user. createWrapper takes the old process func as an input and returns the new wrapper process func. createWrapper should use call the old process func within the new process func.

type UniversalClient 

type UniversalClient interface {
	Cmdable
	Process(cmd Cmder) error
	Subscribe(channels ...string) *PubSub
	PSubscribe(channels ...string) *PubSub
	Close() error
}

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) 
package main

import (
	"github.com/go-redis/redis"
)

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

	client.Ping()
}

Output:
Example (Failover) 
package main

import (
	"github.com/go-redis/redis"
)

func main() {
	client := redis.NewUniversalClient(&redis.UniversalOptions{
		MasterName: "master",
		Addrs:      []string{":26379"},
	})
	defer client.Close()

	client.Ping()
}

Output:
Example (Simple) 
package main

import (
	"github.com/go-redis/redis"
)

func main() {
	client := redis.NewUniversalClient(&redis.UniversalOptions{
		Addrs: []string{":6379"},
	})
	defer client.Close()

	client.Ping()
}

Output:

type UniversalOptions 

type UniversalOptions struct {
	// Either a single address or a seed list of host:port addresses
	// of cluster/sentinel nodes.
	Addrs []string

	// The sentinel master name.
	// Only failover clients.
	MasterName string

	// Database to be selected after connecting to the server.
	// Only single-node and failover clients.
	DB int

	// Enables read only queries on slave nodes.
	ReadOnly bool

	MaxRedirects   int
	RouteByLatency bool

	MaxRetries         int
	Password           string
	DialTimeout        time.Duration
	ReadTimeout        time.Duration
	WriteTimeout       time.Duration
	PoolSize           int
	PoolTimeout        time.Duration
	IdleTimeout        time.Duration
	IdleCheckFrequency time.Duration
}

UniversalOptions information is required by UniversalClient to establish connections.
