Class	Description
CompactionState	This class describes what compaction task spec was used to create a given segment.
DataSegment	Metadata of Druid's data segment.
DataSegment.Builder
DataSegment.PruneSpecsHolder	This class is needed for optional injection of pruneLoadSpec and pruneLastCompactionState, see github.com/google/guice/wiki/FrequentlyAskedQuestions#how-can-i-inject-optional-parameters-into-a-constructor
LogicalSegment	A logical segment can represent an entire segment or a part of a segment.
LogicalSegment.Status
Overshadowable<T extends Overshadowable<T>>	Interface to represent a class which can have overshadow relation between its instances.
Partitions	This enum is used a parameter for several methods in VersionedIntervalTimeline, specifying whether only complete partitions should be considered, or incomplete partitions as well.
PruneLastCompactionState	This annnotation is used to inject a boolean parameter into a DataSegment constructor, which prescribes to drop deserialized "lastCompactionState" and don't store it in a field of a DataSegment.
PruneLoadSpec	This annnotation is used to inject a boolean parameter into a DataSegment constructor, which prescribes to drop deserialized "loadSpec" and don't store it in a field of a DataSegment.
SegmentId	Identifier of DataSegment.
SegmentStatusInCluster	This class represents the current state of a segment in the cluster and encapsulates the following: the DataSegment object overshadowed status of the segment replication factor of the segment number of rows in the segment if the segment is realtime Objects of this class are used to sync the state of segments from the Coordinator to different services, typically the Broker.
SegmentTimeline	VersionedIntervalTimeline for DataSegment objects.
TimelineLookup<VersionType,ObjectType extends Overshadowable<ObjectType>>
TimelineObjectHolder<VersionType,ObjectType extends Overshadowable<ObjectType>>
VersionedIntervalTimeline<VersionType,ObjectType extends Overshadowable<ObjectType>>	VersionedIntervalTimeline is a data structure that manages objects on a specific timeline.
VersionedIntervalTimeline.PartitionChunkEntry<VersionType,ObjectType>	Stores a PartitionChunk for a given interval and version.
