can't set the redis DB number?

[trkjoy]

Look at the source code, can't set the redis DB number，ｗhy to be like this design?
Whether can let go of redis DB Settings?

using pipeline to select db
`
r:=redis.New(xxx)

err = r.Pipelined(func(p redis.Pipeliner) error {
p.Select(1)
return nil
})

because redis cahce should one service one node

as a framework, i think it should provide complete function, not best practice which you think。
because there are more complicated and special scenes and team conditions .

go-zero is a excellent framework, now we use it by changing source code because of this feature, i think this's not a overly feature, can consider it again?

thanks.

One node ≠ One Database!

Redis support Database Number functional, and it real can support more scencs,

Hi @kevwan , many user has different purpose to use Redis.

I readed the #652, but more DevOps work is not good idea -- go-zero support more functional, and like we, the "many redis db" is real required (we hug the mirco service frame work, and only has one redis server).

If some group or some scencs really need "single redis db", set normal formulas is good idea, "cut Redis official functional" is weird.

底层 v8 使用连接池，这个被 select 的连接不确定什么时候回收，新建的每个连接都需要 select

This issue is stale because it has been open for 30 days with no activity.

社区这个需求很大，作为框架是应该替使用者考虑各种场景的，最佳实践一个项目一个redis没错，那redis为何要搞多database供开发者选择？不外乎适应开发者更复杂、更个性的使用场景嘛，框架有，开发者用不用是他们的事，用出问题也是他们的事对吧。

There is a huge demand from the community. As a framework, it should consider various scenarios for users. The best practice is to have one redis per project. So why does redis have multiple databases for developers to choose from? It's nothing more than adapting to developers' more complex and personalized usage scenarios. There is a framework, and it's up to the developers whether they use it or not. It's also their business if problems arise after using it, right?
