Interface BatchOperation<I,O>

public interface BatchOperation<I,O>

An operation that consists of a sequence of independent units of work that need to be run as a batch job.

All operations in a batch will be performed sequentially in a single thread (or we'd need a more complex producer/consumer API here), but there is no guarantee that they will be run in the same Hibernate session, transaction, or against the same database connection.
