增加选择redis的数据库的功能
I think the best practice is not to use DB in redis.
这东西就像核武器 可以不用 但是不能没有 框架理论上应该提供完备的能力
如果多应用共用一个db有key冲突的风险(多个应用的key相同了)，所以可以通过选择不同的db来规避，当前也可以在框架里面加各自前缀，但是不能保证所有的key都不冲突覆盖。并且对于key的管理，应用之间错开db使用也利于管理。并且增加一个db的选择，对目前的redis模块的使用来说并没有增加额外操作

If multiple applications share a db, there is a risk of key conflict (the keys of multiple applications are the same), so you can avoid it by selecting different dbs. Currently, you can also add their own prefixes to the framework, but there is no guarantee that all keys will not conflict. cover. And for key management, staggering the use of db between applications is also conducive to management. And adding a db option does not add additional operations to the current use of the redis module

Indeed I think it is necessary.

I raised this question a long time ago. Can't do without. Its not mandatory
I have 2 use-cases below which I think supporting db selection in Redis can bring more benefit to developers:
- Simplify local + dev env setup
- In case 1 Redis db is used for different purposes, for ex: cache + queue, it'll be dangerous to do action "clear cache" which will clear all queue data also.
When we use redis in dev or test environment, we need reuse the redis server with different db. But in prod environment, just use db0.

As a framework, it can be recommended to use the same db, but not without

特别是在测试环境下，有时候需要使用不同的db来隔离数据，不然就需要部署多个redis实例。

In some refactored systems, the data is originally written in a non-zero database. At this time, it is necessary to choose to set the database

As a framework, it is recommended to use the same db, but it cannot be used without it. Test students often have a headache for this. User tables of different applications can sometimes be configured with a redis and cannot be distinguished at all.

It’s 2024, is this still not supported?
