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

             Summary: Port existing Phoenix optimizations to Calcite integration
                 Key: PHOENIX-1784
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1784
             Project: Phoenix
          Issue Type: Task
            Reporter: Maryann Xue


A lot of optimizations are already included in Calcite default rules, but there are still
a few Phoenix-specific high-level optimizations that we need to implement as rules and make
sure they are reflected in the tree's cost.

A simple example can be PhoenixFilterTableScanMergeRule, which pushes a Filter operator into
a PhoenixTableScan so that the filter can be converted to an HBase Filter or more optimally
a SkipScanFilter or even a point look-up.

Please refer to sub-tasks for individual optimizations.
