humengyu created FLINK-21665:
--------------------------------

             Summary: Create catalog statement should support [IF NOT EXIST] and [COMMENT]
                 Key: FLINK-21665
                 URL: https://issues.apache.org/jira/browse/FLINK-21665
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API, Table SQL / Client
            Reporter: humengyu


It is a common scenarioIf that we have multiple catalogs:
 # comment can help us distinguish between different data sources;
 # [IF NOT EXISTS] statement can avoid exception if the catalog already exists.
