public class ParallelFlow
extends Object

A parallel flow executes a set of work units in parallel. A ParallelFlow requires a ExecutorService to execute work units in parallel using multiple threads. It is the responsibility of the caller to manage the lifecycle of the executor service. The status of a parallel flow execution is defined as:

• WorkStatus.COMPLETED: If all work units have successfully completed
• WorkStatus.FAILED: If one of the work units has failed
