[jira] [Created] (CALCITE-2969) Improve design of join-like relational expressions

Stamatis Zampetakis created CALCITE-2969:
--------------------------------------------

             Summary: Improve design of join-like relational expressions
                 Key: CALCITE-2969
                 URL: https://issues.apache.org/jira/browse/CALCITE-2969
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.19.0
            Reporter: Stamatis Zampetakis


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]).
