Throws:

createImmutableSegment

public ImmutableSegment createImmutableSegment(CellComparator comparator)

create empty immutable segment for initializations This ImmutableSegment is used as a place holder for snapshot in Memstore. It won't flush later, So it is not necessary to record the initial size for it.

Parameters:

comparator - comparator

Returns:

ImmutableSegment

createImmutableSegment

public ImmutableSegment createImmutableSegment(MutableSegment segment,
                                               MemStoreSizing memstoreSizing)

createMutableSegment

public MutableSegment createMutableSegment(org.apache.hadoop.conf.Configuration conf,
                                           CellComparator comparator,

createImmutableSegmentByMerge

public ImmutableSegment createImmutableSegmentByMerge(org.apache.hadoop.conf.Configuration conf,
                                                      CellComparator comparator,
