redis client in golang
Go or Golang is an open source programming language that makes it easy to build simple, reliable, and efficient software.
Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
- Pure golang, and doesn't depend on any 3rd party libraries;
- Hight test coverage and will continue to improve;
- Tested under Go 1.2 and Redis 2.8.3;
- Tested under Go 1.2.1 and Redis 2.8.4;
Features
- Python Redis Client Like API
- Support Pipeling
- Support Transaction
- Support Publish Subscribe
- Support Lua Eval
- Support Connection Pool
- Support Dial URL-Like
- Support monitor, sort, scan, slowlog .etc

Simple Example
Connect:
client, err := Dial()
client, err := Dial(&DialConfig{Address: "127.0.0.1:6379"})
client, err := DialURL("tcp://auth:password@127.0.0.1:6379/0?timeout=10s&maxidle=1")
Try a redis command is simple too, let's do GET/SET:
err := client.Set("key", "value", 0, 0, false, false)
value, err := client.Get("key")
Or you can execute a custom command with Redis.ExecuteCommand method:
reply, err := client.ExecuteCommand("SET", "key", "value")
err := reply.OKValue()
And then a Reply struct which represent the redis response data is defined:
type Reply struct {
Type int
Error string
Status string
Integer int64 // Support Redis 64bit integer
Bulk []byte // Support Redis Null Bulk Reply
Multi []*Reply
}
Reply.Type is defined as:
const (
ErrorReply = iota
StatusReply
IntegerReply
BulkReply
MultiReply
)
Reply struct has many useful methods:
func (rp *Reply) IntegerValue() (int64, error)
func (rp *Reply) BoolValue() (bool, error)
func (rp *Reply) StatusValue() (string, error)
func (rp *Reply) OKValue() error
func (rp *Reply) BytesValue() ([]byte, error)
func (rp *Reply) StringValue() (string, error)
func (rp *Reply) MultiValue() ([]*Reply, error)
func (rp *Reply) HashValue() (map[string]string, error)
func (rp *Reply) ListValue() ([]string, error)
func (rp *Reply) BytesArrayValue() ([][]byte, error)
func (rp *Reply) BoolArrayValue() ([]bool, error)
You can find more examples in test files.
