[jira] [Commented] (HIVE-7111) Extend join transitivity PPD to non-column expressions

    [ https://issues.apache.org/jira/browse/HIVE-7111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14249569#comment-14249569 ] 

Navis commented on HIVE-7111:
-----------------------------

[~leftylev] Seemed not need any documentation. And it's extension of PPD rather than join optimization.

> Join transitive in PPD only supports column expressions, but it's possible to extend this to generic expressions.
