class ApplyInPandasWithStatePythonRunner extends BasePythonRunner[InType, OutType] with PythonArrowInput[InType] with PythonArrowOutput[OutType]
A variant implementation of ArrowPythonRunner to serve the operation applyInPandasWithState.
Unlike normal ArrowPythonRunner which both input and output (executor <-> python worker) are InternalRow, applyInPandasWithState has side data (state information) in both input and output along with data, which requires different struct on Arrow RecordBatch.
