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

If you are using Redis 6, install go-redis/v8:

go get github.com/APITeamLimited/redis/v8

If you are using Redis 7, install go-redis/v9:

go get github.com/APITeamLimited/redis/v9

Quickstart

import (
    "context"
    "github.com/APITeamLimited/redis/v8"
    "fmt"
)

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.

}

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

Client creates and frees connections automatically; it also maintains a free pool of idle connections. You can control the pool size with Config.PoolSize option.

Example 
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, "missing_key").Result()
if err == redis.Nil {
	fmt.Println("missing_key does not exist")
} else if err != nil {
	panic(err)
} else {

}

Output:

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.

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()

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")
}

			fmt.Println("increment error:", err)
		}
	}()
}
wg.Wait()

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

type Conn 

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

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()

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

type Pipeline 

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

}

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(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(opts ...ChannelOption) <-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.

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

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
	AddHook(Hook)
	Watch(ctx context.Context, fn func(*Tx) error, keys ...string) error
	Do(ctx context.Context, args ...interface{}) *Cmd
	Process(ctx context.Context, cmd Cmder) error
	Subscribe(ctx context.Context, channels ...string) *PubSub
	PSubscribe(ctx context.Context, channels ...string) *PubSub
	Close() error
	PoolStats() *PoolStats
}

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

	Username         string
	Password         string
	SentinelUsername string
	SentinelPassword string

	MaxRetries      int
	MinRetryBackoff time.Duration
	MaxRetryBackoff time.Duration

	DialTimeout  time.Duration
	ReadTimeout  time.Duration
	WriteTimeout time.Duration

	// PoolFIFO uses FIFO mode for each node connection pool GET/PUT (default LIFO).
	PoolFIFO bool

	PoolSize        int
	PoolTimeout     time.Duration
	MinIdleConns    int
	MaxIdleConns    int
	ConnMaxIdleTime time.Duration

}

UniversalOptions information is required by UniversalClient to establish connections.

func (*UniversalOptions) Cluster 

func (o *UniversalOptions) Cluster() *ClusterOptions

Cluster returns cluster options created from the universal options.

func (*UniversalOptions) Failover 

func (o *UniversalOptions) Failover() *FailoverOptions

Failover returns failover options created from the universal options.

func (*UniversalOptions) Simple 

func (o *UniversalOptions) Simple() *Options

Simple returns basic options created from the universal options.

type XAddArgs 

type XAddArgs struct {
	Stream     string
	NoMkStream bool
	MaxLen     int64 // MAXLEN N
	MinID      string
	// Approx causes MaxLen and MinID to use "~" matcher (instead of "=").
	Approx bool
	Limit  int64
	ID     string
	Values interface{}
}

XAddArgs accepts values in the following formats:

  • XAddArgs.Values = []interface{}{"key1", "value1", "key2", "value2"}
  • XAddArgs.Values = []string("key1", "value1", "key2", "value2")
  • XAddArgs.Values = map[string]interface{}{"key1": "value1", "key2": "value2"}

Note that map will not preserve the order of key-value pairs. MaxLen/MaxLenApprox and MinID are in conflict, only one of them can be used.

ZAddArgs WARN: The GT, LT and NX options are mutually exclusive.

type ZRangeArgs 

type ZRangeArgs struct {
	Key string

	// When the ByScore option is provided, the open interval(exclusive) can be set.
	// By default, the score intervals specified by <Start> and <Stop> are closed (inclusive).
	// It is similar to the deprecated(6.2.0+) ZRangeByScore command.
	// For example:
	//		ZRangeArgs{
	//			Key: 				"example-key",
	//	 		Start: 				"(3",
	//	 		Stop: 				8,
	//			ByScore:			true,
	//	 	}
	// 	 	cmd: "ZRange example-key (3 8 ByScore"  (3 < score <= 8).
	//
	// For the ByLex option, it is similar to the deprecated(6.2.0+) ZRangeByLex command.
	// You can set the <Start> and <Stop> options as follows:
	//		ZRangeArgs{
	//			Key: 				"example-key",
	//	 		Start: 				"[abc",
	//	 		Stop: 				"(def",
	//			ByLex:				true,
	//	 	}
	//		cmd: "ZRange example-key [abc (def ByLex"
	//
	// For normal cases (ByScore==false && ByLex==false), <Start> and <Stop> should be set to the index range (int).
	// You can read the documentation for more information: https://redis.io/commands/zrange
	Start interface{}
	Stop  interface{}

	// The ByScore and ByLex options are mutually exclusive.
	ByScore bool
	ByLex   bool

	Rev bool

	// limit offset count.
	Offset int64
	Count  int64
}

ZRangeArgs is all the options of the ZRange command. In version> 6.2.0, you can replace the(cmd): 

ZREVRANGE,
ZRANGEBYSCORE,
ZREVRANGEBYSCORE,
ZRANGEBYLEX,
ZREVRANGEBYLEX.

Please pay attention to your redis-server version.

Rev, ByScore, ByLex and Offset+Count options require redis-server 6.2.0 and higher.
