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

Is something wrong with the tests? Some runs finish 6500 tests, some only 1600.

> 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}}.
