[jira] [Created] (PHOENIX-6767) Traversing through all the guideposts to prepare parallel scans is not required for salted tables when the query is point lookup

Rajeshbabu Chintaguntla created PHOENIX-6767:
------------------------------------------------

             Summary: Traversing through all the guideposts to prepare parallel scans is not required for salted tables when the query is point lookup
                 Key: PHOENIX-6767
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6767
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Rajeshbabu Chintaguntla
            Assignee: Rajeshbabu Chintaguntla
             Fix For: 5.2.0


Currently even when the query is point lookup on salted table we are traversing through region boundaries or guideposts to create parallel scans which is not required and adding overhead to point lookup queries even we know the exact region or guide post need to be scanned to find the results. When the guide posts are high or number of regions are high leading higher latencies for point lookup query.
