PythonStreamingQueryListener

class PythonStreamingQueryListener extends StreamingQueryListener

A helper class for handling StreamingQueryListener related functionality in Spark Connect. Each instance of this class starts a python process, inside which has the python handling logic. When a new event is received, it is serialized to json, and passed to the python process.
