--------------------------------------------
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]).
