[jira] [Commented] (HIVE-24365) SWO should not create complex and redundant filter expressions

    [ https://issues.apache.org/jira/browse/HIVE-24365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17229364#comment-17229364 ] 

Zoltan Haindrich commented on HIVE-24365:
-----------------------------------------


* in case 2 TS is merged by SWO ; the FIL expression is corrected to filter for only that branch
* note that any further changes to the above created FIL expression may not change the results

> for q88 we have complex and mostly unreadable filter expressions; because before merging 2 branches the TS filterexpression is pushed into a FIL operator.
