             Summary: Optimize logical Table API plans in Calcite
                 Key: FLINK-3225
                 URL: https://issues.apache.org/jira/browse/FLINK-3225
             Project: Flink
          Issue Type: Sub-task
          Components: Table API
            Reporter: Fabian Hueske


This task implements the optimization of logical Table API plans with Apache Calcite. The
input of the optimization process is a logical query plan consisting of Calcite RelNodes.
FLINK-3223 translates Table API queries into this representation.

The result of this issue is an optimized logical plan.

Calcite's rule-based optimizer applies query rewriting and optimization rules. For Batch SQL,
we can use (a subset of) Calcite’s default optimization rules. 
For this issue we have to 
- add the Calcite optimizer to the translation process
- select an appropriate set of batch optimization rules from Calcite’s default rules. We
can reuse the rules selected by Timo’s first SQL implementation.
