[jira] [Commented] (CALCITE-533) Support for grouping sets in FilterAggregateTransposeRule

["Jesus Camacho Rodriguez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CALCITE-533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14248404#comment-14248404 ] 

Jesus Camacho Rodriguez commented on CALCITE-533:
-------------------------------------------------

I [extended the rule|https://github.com/apache/incubator-calcite/pull/34], as in some cases it seems possible to (partially) push the {{Filter}} through the {{Aggregate}} if grouping sets are used if:
- The {{Aggregate}} operator does not include aggregation functions, and
- The columns referenced in the {{Filter}} predicate are present in all the grouping sets.

> FilterAggregateTransposeRule should support aggregation using grouping sets. Tests to check correctness should be added.
