Methods in org.apache.hadoop.hbase.regionserver that return MutableSegment

Modifier and Type	Method and Description
MutableSegment	SegmentFactory.createMutableSegment(org.apache.hadoop.conf.Configuration conf, CellComparator comparator, MemStoreSizing memstoreSizing)
private MutableSegment	SegmentFactory.generateMutableSegment(org.apache.hadoop.conf.Configuration conf, CellComparator comparator, MemStoreLAB memStoreLAB, MemStoreSizing memstoreSizing)
(package private) MutableSegment	AbstractMemStore.getActive()

Methods in org.apache.hadoop.hbase.regionserver with parameters of type MutableSegment

Modifier and Type	Method and Description
protected boolean	CompactingMemStore.checkAndAddToActiveSize(MutableSegment currActive, Cell cellToAdd, MemStoreSizing memstoreSizing) Check whether anything need to be done based on the current active set size.
ImmutableSegment	SegmentFactory.createImmutableSegment(MutableSegment segment, MemStoreSizing memstoreSizing)
protected void	AbstractMemStore.doAdd(MutableSegment currentActive, Cell cell, MemStoreSizing memstoreSizing)
private void	AbstractMemStore.doUpsert(MutableSegment currentActive, Cell cell, long readpoint, MemStoreSizing memstoreSizing)
protected void	CompactingMemStore.flushInMemory(MutableSegment currActive)
private void	AbstractMemStore.internalAdd(MutableSegment currentActive, Cell toAdd, boolean mslabUsed, MemStoreSizing memstoreSizing)
private Cell	AbstractMemStore.maybeCloneWithAllocator(MutableSegment currentActive, Cell cell, boolean forceCloneOfBigCell) If the segment has a memory allocator the cell is being cloned to this space, and returned; Otherwise the given cell is returned When a cell's size is too big (bigger than maxAlloc), it is not allocated on MSLAB.
protected void	CompactingMemStore.postUpdate(MutableSegment currentActive)
protected void	DefaultMemStore.postUpdate(MutableSegment currentActive)
protected abstract void	AbstractMemStore.postUpdate(MutableSegment currentActive) Issue any post update synchronization and tests
protected boolean	CompactingMemStore.preUpdate(MutableSegment currentActive, Cell cell, MemStoreSizing memstoreSizing) Issue any synchronization and test needed before applying the update For compacting memstore this means checking the update can increase the size without overflow
protected boolean	DefaultMemStore.preUpdate(MutableSegment currentActive, Cell cell, MemStoreSizing memstoreSizing)
protected abstract boolean	AbstractMemStore.preUpdate(MutableSegment currentActive, Cell cell, MemStoreSizing memstoreSizing) Issue any synchronization and test needed before applying the update
protected void	CompactingMemStore.pushActiveToPipeline(MutableSegment currActive, boolean checkEmpty) NOTE: When CompactingMemStore.flushInMemory(MutableSegment) calls this method, due to concurrent writes and because we first add cell size to currActive.getDataSize and then actually add cell to currActive.cellSet, it is possible that currActive.getDataSize could not accommodate cellToAdd but currActive.cellSet is still empty if pending writes which not yet add cells to currActive.cellSet,so for CompactingMemStore.flushInMemory(MutableSegment),checkEmpty parameter is false.
boolean	CompactionPipeline.pushHead(MutableSegment segment)
private void	CompactingMemStore.tryFlushInMemoryAndCompactingAsync(MutableSegment currActive) Try to flush the currActive in memory and submit the background CompactingMemStore.InMemoryCompactionRunnable to RegionServicesForStores.getInMemoryCompactionPool().
