Jinfeng Ni commented on CALCITE-1321:
-------------------------------------
The majority of code change seems to new unit test, which has better put the
expected explain result in SqlToRelConveterTest.xml, in stead of in
SqlToRelConverterTest.java.
I agree the transformation had better expressed as a planner rule, so that
people has the control whether they want such transformation, and when they
want to apply such transformation. Using SqlToRelConverter property is a step
towards the first goal.
> In-list to join optimization should have configurable in-list size
