public interface PartitionAwareOperation

An interface that can be implemented by an operation to indicate that is should be invoked on a particular partition. This interface only has means for documentation purposes. Because every operation has a Operation.getPartitionId() method, the system will use that to determine if an Operation is partition-aware. So the system is fine if you create an Operation that doesn't implements PartitionAwareOperation, but returns a partitionId equal or larger than 0 (and therefor is partition-specific). But it is also fine if you do implement this PartitionAwareOperation interface, and return -1 as partition ID (and therefor is not specific to a partition).
