Subject [jira] [Commented] (PHOENIX-5112) Simplify QueryPlan selection in Phoenix.
Date Fri, 24 May 2019 21:33:00 GMT

Thomas D'Silva commented on PHOENIX-5112:
-----------------------------------------

+1 LGTM. 
[~jamestaylor] The tests are passing on the 4.14 branches. I will file JIRAs to fix the tests
failing on the 4.x and master branches so that we can get 4.15 released.

> 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}}.
