>
> FLINK-6962 has introduced a basic SQL DDL to create a table. However, it
> doesn't support stream specific features, for example, watermark definition,
> changeflag definition, computed columns, primary keys and so on.
> We started a FLIP design doc[1] to discuss the concepts of source and sink to
> help us have a well-defined DDL. Once the FLIP is accepted, we can start the
> work.
