Julian Hyde commented on CALCITE-2201:
--------------------------------------
bq. can you please clarify if {LogicalProject(input=JdbcTableScan)}} is
supposed to happen
Yes. We have always allowed physical tables to exist in a logical plan. (We
could perhaps have done it differently, and we could perhaps change the rules,
but only if the benefit is significant.)
> Allow passing custom RelBuilder into RelDecorrelator and
> RelStructuredTypeFlattener

>
> When {{RelDecorrelator.decorrelateQuery()}} method is called,
> {{RelDecorrelator}} instance with {{RelFactories.LOGICAL_BUILDER}} is
> created. We should modify this method to allow usage of custom {{RelBuilder}}.
> Also, {{RelStructuredTypeFlattener}} class should be modified in a similar
> way.
