             Summary: Clean up catalog API on default/current DB
                 Key: FLINK-12469
                 URL: https://issues.apache.org/jira/browse/FLINK-12469
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
    Affects Versions: 1.9.0
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang


Currently catalog API has get/setCurrentDatabase(), which is more user session specific. In our design principal, catalog instance is agnostic to user sessions. Thus, current database concept doesn't belong there. However, a catalog should support a (configurable) default database, which would be taken as user's current database when user's session doesn't specify a current DB.

This JIRA is to remove current database concept from catalog api and add default database instead.
