wuchong opened a new pull request #8695: [FLINK-12805][FLINK-12808][FLINK-12809][table-api] Introduce PartitionableTableSource and PartitionableTableSink and OverwritableTableSink
URL: https://github.com/apache/flink/pull/8695
 
 
   
   ## What is the purpose of the change
   
   Introduce `PartitionableTableSource` for partition pruning, and introduce `OverwritableTableSink` for supporting insert overwrite, and introduce `PartitionableTableSink` for support writing data into partitions.
   
   All of them are only supported in Blink planner in the first version.
   
   ## Brief change log
   
   This pull request only contains the three interface. We didn't include any implementations because: 
    - `OverwritableTableSink` depends on the `INSERT OVERWRITE` syntax. 
    - `PartitionableTableSink` depends on the `INSERT PARTITION` syntax.
    - `PartitionableTableSource` depends on the filter pushdown optimization implementation in Blink planner.
