Interface DistributedTypedRecordProcessor<T extends UnifiedRecordValue>

Type Parameters:
T -
All Superinterfaces:
TypedRecordProcessor<T>
All Known Implementing Classes:
DeploymentCreateProcessor, ResourceDeletionDeleteProcessor, SignalBroadcastProcessor
public interface DistributedTypedRecordProcessor<T extends UnifiedRecordValue> extends TypedRecordProcessor<T>
Some commands are distributed to different partitions. During distribution the command gets written on the other partitions. Depending on whether it is distributed the behavior of the processor may slightly change. For example, if it was distributed before we don't want to distribute it a second time.

This interface provides some convenience for commands that get distributed. Instead of checking if the command was distributed in the processor directly, the interface taskes care of it.
