             Summary: Perform binary search on guideposts during query 
                 Key: PHOENIX-4594
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4594
             Project: Phoenix
          Issue Type: Improvement
            Reporter: James Taylor

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.
