Class PythonOutputSelector

java.lang.Object

org.apache.flink.streaming.python.api.functions.PythonOutputSelector

All Implemented Interfaces:

Serializable, org.apache.flink.streaming.api.collector.selector.OutputSelector<org.python.core.PyObject>

public class PythonOutputSelector
extends Object
implements org.apache.flink.streaming.api.collector.selector.OutputSelector<org.python.core.PyObject>

The PythonOutputSelector is a thin wrapper layer over a Python UDF OutputSelector. It receives an OutputSelector as an input and keeps it internally in a serialized form. It is then delivered, as part of the job graph, up to the TaskManager, then it is opened and becomes a sort of mediator to the Python UDF OutputSelector.

This function is used internally by the Python thin wrapper layer over the streaming data functionality
