godfreyhe opened a new pull request #16599:
URL: https://github.com/apache/flink/pull/16599
## What is the purpose of the change
*The reason about the unstable test cases is the inner serializer instance
in RawType is serialized directly as String to json which is mutable. While for
a RawType representing DataView, the inner logical type is stable and
accessible, we should serialize the inner logical type to make the json plan
stable. For other case, we just keep the previous behavior. This pr aims to fix
it*
## Brief change log
- *serialize the inner logical type for the RawType representing DataView*
## Verifying this change
This change is already covered by existing tests, such as
*LogicalTypeSerdeTest, IncrementalAggregateJsonPlanTest*.
