[jira] [Commented] (CALCITE-2291) Add rule to push Project past Correlate

    [ https://issues.apache.org/jira/browse/CALCITE-2291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16522190#comment-16522190 ] 

Volodymyr Vysotskyi commented on CALCITE-2291:
----------------------------------------------

[~cshi], I have added [~HanumathRao]'s fix for Unnest and added fixes for this rule with ANTI and SEMI correlate and fix to update {{RelDataType}} for {{RexCorrelVariable}} when the rule is applied.

Could you please review these changes in my branch [CALCITE-2291|https://github.com/vvysotskyi/calcite/tree/CALCITE-2291]?
If all is ok, I think we can merge it to the master.

> Correlate is not derived from Join so we need a rule similar to ProjectJoinTransposeRule to push Project to under Correlate.
