redigo长连接/复用

Connecting to Redigo and manipulating data inside a function is easy like butter, but the problem comes when you have to re-use its connection, obviously for performance/practicality reasons.

 How do you go about re-using (not recreating everytime) a Redigo connection?

最佳答案：

The best way turned out to be using Pools, which are briefly documented here: Redigo Pools.

A global variable won't eventually reuse a connection, so I ended up with something like this (using Pools as noted before):

func newPool() *redis.Pool {return &redis.Pool{            MaxIdle: 80,            MaxActive: 12000, // max number of connections            Dial: func() (redis.Conn, error) {                    c, err := redis.Dial("tcp", ":6379")                    if err != nil {                            panic(err.Error())                    }                    return c, err            },    } }var pool = newPool()func main() {        c := pool.Get()        defer c.Close()        test,_:=c.Do("HGETALL", "test:1")        fmt.Println(test)}

If for example you want to reuse a pool inside another function you do it like this:

func test() {        c := pool.Get()        defer c.Close()        test2,_:=c.Do("HGETALL", "test:2")        fmt.Println(test2)}
