-------------------------------------------------
[~jamestaylor] I can try having a go at this if you're not already working on
this.
> Perform binary search on guideposts during query compilation

> Key: PHOENIX-4594
> URL: https://issues.apache.org/jira/browse/PHOENIX-4594
> Project: Phoenix
> Issue Type: Improvement
> Reporter: James Taylor
> Priority: Major
>
> 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.
