---------------------------------------------------------------------------
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 columns referenced in the {{Filter}} predicate are present in all the
grouping sets.

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.
