> The existing join-like (Join, SemiJoin, Correlate, etc.) logical and physical relational expressions have a few design issues which make some parts of the codebase complicated and difficult to understand.
> The goal of this ticket is to improve the design of the respective expressions based on the discussion in the dev list (see thread [Join, SemiJoin, Correlate|https://mail-archives.apache.org/mod_mbox/calcite-dev/201903.mbox/%3C8EEA04A0-4A77-4283-BD20-B019E19AE126%40apache.org%3E]).
