Cache Sharding support to increase performance

[Planxnx]

add cache shards will reduce r/w blocking by mutex.

Given the internalization of a mutex, this would seem to be a valuable feature. Is this feature being considered?

[swithek]

Yes, though there are no plans for its release yet.

[sammy-hughes]

Yep. The distance between "that's a good idea" and "all done!" can be quite the doozy. Thanks for confirming that this is somewhere in the roadmap.

I'm still waiting 👀
