[jira] [Created] (PHOENIX-6986) Add property to disable server merges for hinted uncovered indexes

Istvan Toth created PHOENIX-6986:
------------------------------------

             Summary: Add property to disable server merges for hinted uncovered indexes
                 Key: PHOENIX-6986
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6986
             Project: Phoenix
          Issue Type: Improvement
          Components: core
            Reporter: Istvan Toth


The new server merge query plan can perform worse than the old skip-join-scan plan.
Add a property to completely disable it.
This should help with migrating workloads to the new version, without having to verify if server merge performs well, and having add hints to disable it where needed.
