Zhen Chen commented on CALCITE-7039:
------------------------------------
[~mbudiu] My expression might not be high-level enough. What I can think of is
that currently, PlannerImpl does not support customizing Volcano rule sets,
which limits its usage. For example, I want to remove some EnumerableRules for
testing purposes, or use JdbcRules for testing. The goal is to make this
utility class more versatile in terms of capabilities.
