Volodymyr Vysotskyi commented on CALCITE-2201:
----------------------------------------------
[~julianhyde], there is nothing special in this pull request, just added a
possibility to pass custom {{RelBuilder}} into {{RelOptUtil}} and
{{JoinCommuteRule}} and made deprecated old methods without {{RelBuilder}} in
the arguments list (there are added/exist methods with the same list of
arguments + {{RelBuilder}}).
In {{RelDecorrelator}} made changes to use passed {{RelBuilder}} in the rules
which used in this class.
In {{RelStructuredTypeFlattener}} made changes to use "new" methods from
{{RelOptUtil}}, etc...
Also, "mvn verify" succeed.
Please let me know if I should make some additional changes in this PR.

> Priority: Major

> 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.
