Subject [jira] [Commented] (PHOENIX-5112) Simplify QueryPlan selection in Phoenix.
Date Mon, 20 May 2019 06:45:00 GMT

Lars Hofhansl commented on PHOENIX-5112:
----------------------------------------

Yep. Filed PHOENIX-5115 a while ago. But not for the other tests.

There used to be leverage in saying "No more releases until all tests pass." But these days
nobody seems to care if there's no release for 1/2 year.

> Brought to light in part in PHOENIX-5109, plan selection in Phoenix is too complicated
with its logic spread over multiple areas. My recent changes let most index through the initial
filters and next step is to put all the logic in {{QueryOptimizer.orderPlansBestToWorst}}.
> One exception is plans with global indexes for queries with uncovered queries, those
should still be handled in {{addPlan}}.
