When `redis-databases` > 0, it switches between databases (0 to redis-databases-1). Database 0 uses the default namespace, databases 1-N use `db1`, `db2`, etc. Enabling this disables custom namespaces. Use [the namespace feature](https://kvrocks.apache.org/docs/namespace) for multiple isolated databases without `redis-databases`. Review Comment: ```suggestion Before 2.15.0, Kvrocks only allowed using [the namespace feature](https://kvrocks.apache.org/docs/namespace) to isolate your data. That said, the `SELECT` command is just a placeholder and does not switch between databases. And now, the Redis database mechanism is supported, and you can enable it by setting the `redis-database` to the database number you expect in the configuration file. To be noticed, we don't allow using the namespace feature and the Redis database at the same time. -- This is an automated message from the Apache Git Service.
