PythonForeachBatchFunction

trait PythonForeachBatchFunction extends AnyRef

Interface that is meant to be extended by Python classes via Py4J. Py4J allows Python classes to implement Java interfaces so that the JVM can call back Python objects. In this case, this allows the user-defined Python foreachBatch function to be called from JVM when the query is active.
