Subject Re: Affinity colocation and sql queries

Hello!

1) Yes!

2) "almost all the time" is not a very strong constraint here. You might
need to enable distributed joins to get such (partially-collocated) queries
to perform. Your query might still benefit from collocation if query planner
realizes that all keys are located on the same node.

3) No, and no.

4) Having excessive number of caches has performance implications and
unlikely to lead to performance benefits.

Regards,
