I wanted to point out that a bunch of tests in TestExampleQueries rely
on the fact that settting the slice target = 1 will generate plans with
exchanges, which is not true any more. We need to modify those tests as
well so we have exchanges in there, otherwise we may introduce regressions.
Thanks

I noticed that the joins in TestTpchDistributed unit tests are not getting

We do have test coverage for parallel joins elsewhere, especially with TPCH
SF100 tests; so this is an FYI in case you are relying on
TestTpchDistributed for such coverage.
This also raises the importance of plan tracking for more tests. We have
been doing plan tracking for partition pruning tests and it has worked out
quite well.
