Work Description: kennknowles commented on issue #5850: [BEAM-4702]
Re-window into global window after GROUP BY <window> plus a couple other little
fixes
URL: https://github.com/apache/beam/pull/5850#issuecomment-401822302
The failures here indicate actual incorrect tests & queries. For example:
```
JOIN(left.id = right.id)
SELECT ... GROUP BY id, TUMBLE(1 hour)
SELECT ... GROUP BY id, TUMBLE(1 hour)
```
Semantically, there may be a joined row for 1:00pm on the left and 10:00pm
on the right. But by the time the right-hand row for 10:00pm shows up, the left
one may be GC'd.
So this is implicitly, but nondeterministically, joining on the window as
well. Before this PR, we left the windowing strategies for left and right in
place, and asserted that they matched.
