go-redis-pool was designed to implement the read/write split in Redis master-slave mode, and easy way to sharding the data.

Installation

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

go mod init github.com/my/repo
go get github.com/bitleak/go-redis-pool/v2

Quick Start

API documentation and examples are available via godoc

Setup The Master-Slave Pool
pool, err := pool.NewHA(&pool.HAConfig{
    Master: "127.0.0.1:6379",
    Slaves: []string{
        "127.0.0.1:6380",
        "127.0.0.1:6381",
    },
    Password: "", // set master password
    ReadonlyPassword: "", // use password if no set
})

pool.Set(ctx, "foo", "bar", 0)

The read-only commands would go throught slaves and write commands would into the master instance. We use the Round-Robin as default when determing which slave to serve the readonly request, and currently supports:

  • RoundRobin (default)
  • Random
  • Weight

For example, we change the distribution type to Weight:

pool, err := pool.NewHA(&pool.HAConfig{
    Master: "127.0.0.1:6379",
    Slaves: []string{
        "127.0.0.1:6380",  // default weight is 100 if missing
        "127.0.0.1:6381:200", // weight is 200
        "127.0.0.1:6382:300", // weigght is 300
    },
    PollType: pool.PollByWeight,
})

The first slave would serve 1/6 reqeusts, and second slave would serve 2/6, last one would serve 3/6.

Auto Eject The Failure Host
pool, err := pool.NewHA(&pool.HAConfig{
    Master: "127.0.0.1:6379",
    Slaves: []string{
        "127.0.0.1:6380",  // default weight is 100 if missing
        "127.0.0.1:6381:200", // weight is 200
        "127.0.0.1:6382:300", // weigght is 300
    },
    AutoEjectHost: true,
    ServerFailureLimit: 3,
    ServerRetryTimeout: 5 * time.Second,
    MinServerNum: 2,
})

The pool would evict the host if reached ServerFailureLimit times of failure and retry the host after ServerRetryTimeout. The MinServerNum was used to avoid evicting too many and would overrun other alive servers.

Setup The Sharding Pool
pool, err := pool.NewShard(&pool.ShardConfig{
    Shards: []*HAConfig {
        // shard 1
        &pool.HAConfig{
            Master: "127.0.0.1:6379",
            Slaves: []string{
                "127.0.0.1:6380",
                "127.0.0.1:6381",
            },
            DistributeType: pool.DistributeByModular,
            HashFn: hashkit.Xxh3,
        },
        // shard 2
        &pool.HAConfig{
            Master: "127.0.0.1:6382",
            Slaves: []string{
                "127.0.0.1:6383",
            },
            DistributeType: pool.DistributeByModular,
            HashFn: hashkit.Xxh3,
        },
    },
})

pool.Set(ctx, "foo", "bar", 0)

Shard pool use the CRC32 as default hash function when sharding the key, you can overwrite the HashFn in config if wants to use other sharding hash function. The distribution type supports ketama and modular, default is modular.
