[jira] [Created] (FLINK-15970) Optimize the Python UDF execution to only serialize the value

Dian Fu created FLINK-15970:
-------------------------------

             Summary: Optimize the Python UDF execution to only serialize the value
                 Key: FLINK-15970
                 URL: https://issues.apache.org/jira/browse/FLINK-15970
             Project: Flink
          Issue Type: Improvement
          Components: API / Python
            Reporter: Dian Fu
             Fix For: 1.11.0


Currently, the window/timestamp/pane info are also serialized and sent between the Java operator and the Python worker. These informations are useless and after bumping beam to 2.19.0(BEAM-7951), optimization is possible to not serialize these fields.
