using redigo, I create a pool, something like so:
&redis.Pool{
MaxIdle: 80,
MaxActive: 12000, // max number of connections
Dial: func() (redis.Conn, error) {
c, err := redis.Dial("tcp", host+":"+port)
if err != nil {
panic(err.Error())
}
return c, err
}
the problem I have is that for each time I get a new connection, I need to set the db, as I use different db's of redis since I host a number of sites on the VPS.
So, something like this:
conn := pool.Get()
defer conn.Close()
conn.Do("SELECT", dbNumber) //this is the call I want to avoid
Having to select the db each time I work with redis seems redundant and also poses a problem since I use it for sessions i.e. having code that is not mine working with my redis connection from my pool makes it "impossible" to set the correct db for it.
What I would like to do is to set the dbno for the pool so that whenever somebody asks for a new connection from the pool, it comes with the correct db already set i.e. not setting it explicitly each time.
How did you solve this in your applications?
Thanks.
