Package org.apache.druid.segment.realtime.appenderator

Class SegmentIdWithShardSpec

java.lang.Object

org.apache.druid.segment.realtime.appenderator.SegmentIdWithShardSpec

All Implemented Interfaces:

Comparable<SegmentIdWithShardSpec>

public final class SegmentIdWithShardSpec
extends Object
implements Comparable<SegmentIdWithShardSpec>

SegmentId with additional ShardSpec info. equals(java.lang.Object)/hashCode() and compareTo(org.apache.druid.segment.realtime.appenderator.SegmentIdWithShardSpec) don't consider that additinal info. This class is separate from SegmentId because in a lot of places segment ids are transmitted as "segment id strings" that don't contain enough information to deconstruct the ShardSpec. Also, even a single extra field in SegmentId is important, because it adds to the memory footprint considerably.
