dianfu opened a new pull request #9748: [FLINK-14016][python][flink-table-planner] Introduce FlinkLogicalPythonScalarFunctionExec and DataStreamPythonScalarFunctionExec for Python function execution
URL: https://github.com/apache/flink/pull/9748
 
 
   
   ## What is the purpose of the change
   
   *This pull request introduces FlinkLogicalPythonScalarFunctionExec and DataStreamPythonScalarFunctionExec for Python ScalarFunction execution.*
   
   
   ## Brief change log
   
     - *Introduces FlinkLogicalPythonScalarFunctionExec and DataStreamPythonScalarFunctionExec for Python ScalarFunction execution*
