Class BoundedEntryBuffers

java.lang.Object

org.apache.hadoop.hbase.wal.BoundedEntryBuffers

@InterfaceAudience.Private
public class BoundedEntryBuffers
extends Object

Used for BoundedRecoveredEditsOutputSink. The core part of limiting opening writers is it doesn't return chunk only if the heap size is over maxHeapUsage. Thus it doesn't need to create a writer for each region during splitting. The returned EntryBuffers.RegionEntryBuffer will be write to recovered edits file and close the writer immediately. See BoundedRecoveredEditsOutputSink.append(EntryBuffers.RegionEntryBuffer) for more details.
