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

             Summary: Upserts into tables with ROW_TIMESTAMP are extremely slow
                 Key: PHOENIX-6878
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6878
             Project: Phoenix
          Issue Type: Improvement
          Components: core
    Affects Versions: 5.1.3, 5.2.0
            Reporter: Istvan Toth


PHOENIX-4187 changed upserts into tables with ROW_TIMESTAMP fields to always 
refresh the table cache before executing the mutation.

This kills random write performance for such tables, as the Table metadata is 
re-read for every time.
