java.lang.Object

org.apache.flink.python.env.beam.ProcessPythonEnvironmentManager

所有已实现的接口:

AutoCloseable, PythonEnvironmentManager

@Internal
public final class ProcessPythonEnvironmentManager
extends Object
implements PythonEnvironmentManager

The ProcessPythonEnvironmentManager is used to prepare the working dir of python UDF worker and create ProcessPythonEnvironment object of Beam Fn API. It's used when the python function runner is configured to run python UDF in process mode.
