Redis client for Golang Build Status

Supports:

API docs: https://godoc.org/gopkg.in/redis.v5. Examples: https://godoc.org/gopkg.in/redis.v5#pkg-examples.

Installation

Install:

go get gopkg.in/redis.v5

Import:

import "gopkg.in/redis.v5"

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 exists")
	} else if err != nil {
		panic(err)
	} else {
		fmt.Println("key2", val2)
	}
	// Output: key value
	// key2 does not exists
}

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"}, []string{"hello"}).Result()

Overview

Package redis implements a Redis client.

Example (CustomCommand)
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"

	redis "gopkg.in/redis.v5"
)

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
		}
	})
}

type Client

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

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

Example
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 exists")
} else if err != nil {
	panic(err)
} else {
	fmt.Println("key2", val2)
}
Output:

key value
key2 does not exists

func NewClient

func NewClient(opt *Options) *Client

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

Example
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 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
// 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:
