[NEW] Multiple DB supports in cluster mode

[madolson]

Creating an issue for folks to give use-cases for multi-DB support. This is the main source of incompatibility when moving from standalone to Valkey cluster.

This feature was not added in Redis since we considered it an anti-pattern compared to using prefixes.

The main use case that I am aware of that is not covered by using namespaces is the ability to flush or swap DBs.

Does this issue expect to support multiple databases in cluster mode?

I think this is a valuable feature. In production environments, many customers are accustomed to using the multi-DB feature. When migrating from standalone mode to a clustered setup, they expect the provider to offer this capability.

Yes, thanks for you commenting. I made this as a placeholder to follow up about, so haven't fully added the details yet.
