    Description

      Create a rule that can split the expressions in a Project (and optionally also a Filter) into pieces that can be pushed down to Druid and pieces that cannot.

      There is class CalcRelSplitter that can split expressions in a Project and Filter according to specified criteria. An existing rule, ProjectToWindowRule, that uses a sub-class of CalcRelSplitter. This rule could be built along similar lines.
