1651: GROUP BY optimization
===========================
This is IMO a desired optimization, and after all the heavy lifting by Tomas
the patch seems to be in pretty good shape.
I agree it's desirable. To move the patch forward, I need some feedback on the
costing questions, mentioned in my last review, and the overall approach to
planning (considering multiple group by variants).
I'm moving this to the next CF with the hope that more feedback is received.
If you think "Ready for Committer" is a more suitable status, please do update
it as I'm leaving it in Needs Review for now not having the full context.
I don't think anyone reviewed the costing, so I think "needs review" is
appropriate.
