Currently preparing cached plans involve:
- cloning of PlanStage tree, including all their arguments, EExpressions, etc.
- compiling EExpressions
- preparing and linking slots accessors.
Investigate if it is possible to reduce that cost, for example by sharing immutable structures (like EExpressions, slot vectors, etc) and compilation results. And if so, estimate the possible performance impact.
