------------------------------------
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`.
