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.
