[jira] [Created] (FLINK-25805) Use compact DataType serialization for default classes instead of internal ones

Timo Walther created FLINK-25805:
------------------------------------

             Summary: Use compact DataType serialization for default classes instead of internal ones
                 Key: FLINK-25805
                 URL: https://issues.apache.org/jira/browse/FLINK-25805
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Timo Walther


It is more likely that default conversion classes spam the plan than internal classes. In most cases when internal classes are used, they usually also use logical type instead of data type. So it should be safer to skip default conversion classes. This also reduces the plan size for serializing `ResolvedSchema`.
