----------------------------------

             Summary: make USE_OF_QUERY_GUIDE_POSTS configurable to improve query performance.
                 Key: PHOENIX-6012
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6012
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Chen Feng


Loading guide posts from SYSTEM.STATS can cost lots of time.

When we have knowledge of the data size covered by query scan, we can disable the use of guide posts to improve query performance.
