Hello, I am looking at the new APIs for state processing [1] and I see custom serde should be supported with a property like "fields.#.value-type-factory". However, I'm not sure if that applies to MapState. I have an operator with MapState using String as key but with a custom type serializer for the values [2], and regardless of how I define my value type factory, I get an exception stating that the new serializer must be compatible with the old one, where both the old and new serializers just mention its the map serializer.
Am I missing something or is this actually not supported yet? [1] https://nightlies.apache.org/flink/flink-docs-release-2.1/docs/libs/state_processor_api/#table-api [2] https://gist.github.com/asardaes/714b8c1db0c4020f5fde9865b95fc398 Regards, Alexis.
