Explanation:
Data Pump jobs use a master table, a master process, and worker processes to perform the work and keep track of progress. For every Data Pump Export job and Data Pump Import job, a master process is created. The master process controls the entire job, including communicating with the clients, creating and controlling a pool of worker processes, and performing logging operations.
