Interface EventSerDe

All Superinterfaces:

AutoCloseable, Closeable, EventDeserializer, EventSerializer, Resettable

@InterfaceAudience.LimitedPrivate(value="future public api")
 @InterfaceStability.Unstable
public interface EventSerDe
extends EventSerializer, EventDeserializer

A class that is able to both serialize and deserialize events.

Implementing this interface does not simply mean that a class has both serialization and deserialization capability. By implementing this interface, implementations guarantee that they can convert a serialized event back to a deserialized event, and back to a serialized event again without any data loss.

That guarantee allows Flume to "replay" partial file writes and restore output files that may have been damaged in a system crash. At the time of this writing, support for this functionality is still lacking.
