[PR] Use filters for pruning properly for hash-joins. (druid)
gianm opened a new pull request, #15299:
URL: https://github.com/apache/druid/pull/15299
Native used them too aggressively: it might use filters for the RHS to prune the LHS. MSQ used them not at all. Now, both use them properly, pruning based on base (LHS) columns only.

> LGTM. Should we put something in the docs so users can leverage this and range partitioning for faster querying from deep storage?
Probably a good idea to emphasize that range partitioning is potentially game changing for querying from deep storage. It can have big impact on how much data needs to be fetched per query.
