Ecosystem

Features

Installation

go-redis supports 2 last Go versions and requires a Go version with modules support. So make sure to initialize a Go module:

go mod init github.com/my/repo

And then install go-redis/v8 (note v8 in the import; omitting it is a popular mistake):

go get github.com/go-redis/redis/v8

Quickstart

import (
    "context"
    "github.com/go-redis/redis/v8"
)

var ctx = context.Background()

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

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

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

    val2, err := rdb.Get(ctx, "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
}

Look and feel

Some corner cases:

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

// SET key value keepttl NX
set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()

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

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

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

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

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

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:

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/:

ln -s /usr/bin/redis-server ./go-redis/testdata/redis/src
cp ./go-redis/testdata/redis.conf ./go-redis/testdata/redis/

Lastly, run:

go test

Overview

Package redis implements a Redis client.

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

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

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

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

rdb.Ping(ctx)
Output:

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

Examples

Constants

View Source
const KeepTTL = -1

KeepTTL is a Redis KEEPTTL option to keep existing TTL, it requires your redis-server version >= 6.0, otherwise you will receive an error: (error) ERR syntax error. For example:

rdb.Set(ctx, key, value, redis.KeepTTL)
View Source
const Nil = proto.Nil

Nil reply returned by Redis when key does not exist.

View Source
const TxFailedErr = proto.RedisError("redis: transaction failed")

TxFailedErr transaction redis failed.

Variables

View Source
var ErrClosed = pool.ErrClosed

ErrClosed performs any operation on the closed client will return this error.

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
}

ch := sub.Channel()

pipe.Expire(ctx, "tx_pipeline_counter", time.Hour)

// Execute
//
//     MULTI
//     INCR pipeline_counter

Example
const maxRetries = 1000

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

		// Actual opperation (local in optimistic lock).
		n++

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

	for i := 0; i < maxRetries; i++ {
		err := rdb.Watch(ctx, txf, key)
		if err == nil {
			// Success.
			return nil
		}
		if err == redis.TxFailedErr {
			// Optimistic lock lost. Retry.
			continue
		}
		// Return any other error.
		return err
	}

	return errors.New("increment reached maximum number of retries")
}

var wg sync.WaitGroup
for i := 0; i < 100; i++ {
	wg.Add(1)
	go func() {
		defer wg.Done()

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

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

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

rdb.Watch(ctx, func(tx *redis.Tx) error {
	tx.Ping(ctx)
	tx.Ping(ctx)
	return nil
}, "foo")

type Conn

type Conn struct {

Conn represents a single Redis connection rather than a pool of connections. Prefer running commands from Client unless there is a specific need for a continuous single Redis connection.

Example
conn := rdb.Conn(context.Background())

err := conn.ClientSetName(ctx, "foobar").Err()
if err != nil {
	panic(err)
}

// Open other connections.
for i := 0; i < 10; i++ {
	go rdb.Ping(ctx)
}

s, err := conn.ClientGetName(ctx).Result()
if err != nil {
	panic(err)
}
fmt.Println(s)
Output:

func ParseURL

func ParseURL(redisURL string) (*Options, error)

ParseURL parses an URL into Options that can be used to connect to Redis. Scheme is required. There are two connection types: by tcp socket and by unix socket. Tcp connection:

redis://<user>:<password>@<host>:<port>/<db_number>

Unix connection:

unix://<user>:<password>@</path/to/redis.sock>?db=<db_number>

Most Option fields can be set using query parameters, with the following restrictions:

  • field names are mapped using snake-case conversion: to set MaxRetries, use max_retries
  • only scalar type fields are supported (bool, int, time.Duration)
  • for time.Duration fields, values must be a valid input for time.ParseDuration(); additionally a plain integer as value (i.e. without unit) is intepreted as seconds
  • to disable a duration field, use value less than or equal to 0; to use the default value, leave the value blank or remove the parameter
  • only the last value is interpreted if a parameter is given multiple times
  • fields "network", "addr", "username" and "password" can only be set using other URL attributes (scheme, host, userinfo, resp.), query paremeters using these names will be treated as unknown parameters
  • unknown parameter names will result in an error

Examples:

redis://user:password@localhost:6789/3?dial_timeout=3&db=1&read_timeout=6s&max_retries=2
is equivalent to:
&Options{
	Network:     "tcp",
	Addr:        "localhost:6789",
	DB:          1,               // path "/3" was overridden by "&db=1"
	DialTimeout: 3 * time.Second, // no time unit = seconds
	ReadTimeout: 6 * time.Second,
	MaxRetries:  2,
}
Example
opt, err := redis.ParseURL("redis://:qwerty@localhost:6379/1?dial_timeout=5s")
if err != nil {
	panic(err)
}
fmt.Println("addr is", opt.Addr)
fmt.Println("db is", opt.DB)
fmt.Println("password is", opt.Password)
fmt.Println("dial timeout is", opt.DialTimeout)

// Create client as usually.
_ = redis.NewClient(opt)
Output:

addr is localhost:6379
db is 1
password is qwerty
dial timeout is 5s

	Close() error
	Discard() error
	Exec(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

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(ctx, "mychannel1")

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

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

// Publish a message.
err = rdb.Publish(ctx, "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(opts ...ChannelOption) <-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 deprecated

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

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

Deprecated: use Channel(WithChannelSize(size)), remove in v9.

func (*PubSub) ChannelWithSubscriptions

func (c *PubSub) ChannelWithSubscriptions(_ context.Context, 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) Ping

func (c *PubSub) Ping(ctx context.Context, payload ...string) error

func (*PubSub) Receive

func (c *PubSub) Receive(ctx context.Context) (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(ctx, "mychannel2")
defer pubsub.Close()

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

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

		_, err := rdb.Publish(ctx, "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
Output:

func (*PubSub) ReceiveMessage

func (c *PubSub) ReceiveMessage(ctx context.Context) (*Message, error)

ReceiveMessage returns a Message or error ignoring Subscription and Pong messages. This is low-level API and in most cases Channel should be used instead.

func (*PubSub) ReceiveTimeout

func (c *PubSub) ReceiveTimeout(ctx context.Context, 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 in most cases Channel should be used instead.

func (*PubSub) String

func (c *PubSub) String() string

func (*PubSub) Subscribe

func (c *PubSub) Subscribe(ctx context.Context, channels ...string) error

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

func (*PubSub) Unsubscribe

func (c *PubSub) Unsubscribe(ctx context.Context, channels ...string) error

Unsubscribe 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 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.

func NewRing

func NewRing(opt *RingOptions) *Ring
Example
rdb := redis.NewRing(&redis.RingOptions{
	Addrs: map[string]string{
		"shard1": ":7000",
		"shard2": ":7001",
		"shard3": ":7002",

type UniversalClient

type UniversalClient interface {
	Cmdable
	Context() context.Context
	AddHook(Hook)
	Watch(ctx context.Context, fn func(*Tx) error, keys ...string) error
	Do(ctx context.Context, args ...interface{}) *Cmd

}

UniversalClient is an abstract client which - based on the provided options - represents either a ClusterClient, a FailoverClient, or a single-node Client. This can be useful for testing cluster-specific applications locally or having different clients in different environments.

func NewUniversalClient

func NewUniversalClient(opts *UniversalOptions) UniversalClient

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

1. If the MasterName option is specified, a sentinel-backed FailoverClient is returned. 2. if the number of Addrs is two or more, a ClusterClient is returned. 3. Otherwise, a single-node Client is returned.

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

rdb.Ping(ctx)
Output:

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

rdb.Ping(ctx)
Output:

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

rdb.Ping(ctx)
Output:

type UniversalOptions

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

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

	Dialer    func(ctx context.Context, network, addr string) (net.Conn, error)
	OnConnect func(ctx context.Context, cn *Conn) error
