Subject [jira] [Created] (PHOENIX-4616) Move join query optimization out from QueryCompiler into QueryOptimizer

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

             Summary: Move join query optimization out from QueryCompiler into QueryOptimizer
                 Key: PHOENIX-4616
                 URL: https://issues.apache.org/jira/browse/PHOENIX-4616
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Maryann Xue
            Assignee: Maryann Xue


Currently we do optimization for join queries inside QueryCompiler, which makes the APIs and
code logic confusing, so we need to move join optimization logic into QueryOptimizer.
 Similarly, but probably with a different approach, we need to optimize UNION ALL queries
and derived table sub-queries in QueryOptimizer.optimize().
