Examples of TaskExecutorPartitionHandler

org.springframework.batch.core.partition.support.TaskExecutorPartitionHandler
A {@link PartitionHandler} that uses a {@link TaskExecutor} to execute thepartitioned {@link Step} locally in multiple threads. This can be aneffective approach for scaling batch steps that are IO intensive, like directory and filesystem scanning and copying.
By default, the thread pool is synchronous. @author Sebastien Gerard @author Dave Syer @since 2.0
