[jira] [Created] (FLINK-21899) Introduce SOURCE_WATERMARK built-infunction to preserve watermark from source

Jark Wu created FLINK-21899:
-------------------------------

             Summary: Introduce SOURCE_WATERMARK built-infunction to preserve watermark from source
                 Key: FLINK-21899
                 URL: https://issues.apache.org/jira/browse/FLINK-21899
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Jark Wu


The SOURCE_WATERMARK function doesn't have concrete implementation. The {{eval()}} function should throw a meaningful exception message to indicate users the function should only be used in DDL to generate a watermark preserved from source system.
