Julian Hyde commented on CALCITE-4583:
--------------------------------------
The system is already configurable in many, many ways.
(RelBuilder.Config.simplify(); RexSimplifier.simplifyFilterPredicates vs.
simplifyUnknownAsFalse; predicates; executor; Hook.REL_BUILDER_SIMPLIFY;
config.bloat() which controls how project expressions are combined with
underlying expressions). Can you figure out a way to rationalize, not add yet
another knob for people to set wrong?
Reading the javadoc you have written, it is not even obvious how I "turn
simplify on".
> Make simplification controllable in "RelBuilder#filter"
