[jira] [Created] (FLINK-39358) Constraint and watermark should stay while CoA MT if there is no explicit change with schema or contraint definition

Sergey Nuyanzin created FLINK-39358:
---------------------------------------

             Summary: Constraint and watermark should stay while CoA MT if there is no explicit change with schema or contraint definition
                 Key: FLINK-39358
                 URL: https://issues.apache.org/jira/browse/FLINK-39358
             Project: Flink
          Issue Type: Sub-task
            Reporter: Sergey Nuyanzin
            Assignee: Sergey Nuyanzin


The idea is that if existing table has a constraint or watermark

and then there is CoA DDL without schema or constraint definition then the existing constraint/watermark should stay.

 

If there are explicit schema/constraint, then they should be applied
