java.lang.Object

org.apache.kafka.server.log.remote.storage.RemoteLogSegmentId

@InterfaceStability.Evolving
public class RemoteLogSegmentId
extends Object

This class represents a universally unique identifier associated to a topic partition's log segment. This will be regenerated for every attempt of copying a specific log segment in RemoteStorageManager.copyLogSegmentData(RemoteLogSegmentMetadata, LogSegmentData). Once it is stored in remote storage, it is used to access that segment later from remote log metadata storage.
