Jiatao Tao commented on CALCITE-4143:
-------------------------------------
Current we only trim filed before node went into volcano planner. Should do it
again when finished volcano phase.
A case like that, when the filter is pushed through the project, the col that
filter used maybe can be pruned in the project node.
> Trim fields after FilterProjectTransposeRule
