> 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 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.

> Considering the streaming DDL is a huge topic, we decided to split it into separate FLIPs. Here comes the first one.
