org.apache.hadoop.hbase.regionserver.Segment

org.apache.hadoop.hbase.regionserver.ImmutableSegment

org.apache.hadoop.hbase.regionserver.CellArrayImmutableSegment

所有已实现的接口:

MemStoreSizing

@InterfaceAudience.Private
public class CellArrayImmutableSegment
extends ImmutableSegment

CellArrayImmutableSegment extends the API supported by a Segment, and ImmutableSegment. This immutable segment is working with CellSet with CellArrayMap delegatee.
