 * The pipeline and data provider for this test case should make sure that the pipeline runs continuously and the origin
 *  in the pipeline keeps producing records until stopped.
 *
 * Origin has to be Kafka as of now. Make sure that there is continuous supply of data for the pipeline to keep running.
 * For example to test kafka Origin, a background thread could keep writing to the kafka topic from which the
