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
