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

             Summary: Improve drop local index performace
                 Key: PHOENIX-3566
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3566
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Rajeshbabu Chintaguntla
            Assignee: Rajeshbabu Chintaguntla
             Fix For: 4.10.0


When we drop local index we need to scan whole data table and  in the coprocessor prepare
index deletes and write back to the same table which adds lot of overhead to the system. We
can improve the performance by just dropping meta data so during compaction we can check we
can just write the existing indexes data back.
