Subject ProjectJoinTransposeRule
Date Tue, 18 Apr 2017 00:21:13 GMT 
In https://issues.apache.org/jira/browse/CALCITE-1753 <https://issues.apache.org/jira/browse/CALCITE-1753>
we are discussing making ProjectJoinTransposeRule more aggressive in the expressions it pushes
down. (Previously we couldn’t do this because we didn’t know which expressions preserved
nulls.)

Chime in if you think this is a bad idea.
