------------------------------------

             Summary: Add Python building blocks to make sure the basic functionality of Python TableFunction could work
                 Key: FLINK-15972
                 URL: https://issues.apache.org/jira/browse/FLINK-15972
             Project: Flink
          Issue Type: Sub-task
          Components: API / Python
            Reporter: Huang Xingbo
             Fix For: 1.11.0


We need to add a few Python building blocks such as TableFunctionOperation, TableFunctionRowCoder, etc for Python TableFunction execution. TableFunctionOperation is subclass of Operation in Beam and TableFunctionRowCoder, etc are subclasses of Coder in Beam. These classes will be registered into the Beam’s portability framework to make sure they take effects.

This PR makes sure that a basic end to end Python UDTF could be executed.
