Bin Shi updated PHOENIX-4594:
-----------------------------
Description: If there are many guideposts, performance will suffer during query compilation.
(was: If there are many guideposts, performance will suffer during query compilation because
we do a linear search of the guideposts to find the intersection with the scan ranges. Instead,
in BaseResultIterators.getParallelScans() we should populate an array of guideposts and perform
a binary search. )
> Query Compilation where there are many guideposts causes overhead
