Class StripeMultiFileWriter.SizeMultiWriter

java.lang.Object

org.apache.hadoop.hbase.regionserver.AbstractMultiFileWriter

org.apache.hadoop.hbase.regionserver.StripeMultiFileWriter

org.apache.hadoop.hbase.regionserver.StripeMultiFileWriter.SizeMultiWriter

All Implemented Interfaces:

CellSink, ShipperListener

Enclosing class:

StripeMultiFileWriter

public static class StripeMultiFileWriter.SizeMultiWriter
extends StripeMultiFileWriter

MultiWriter that separates the cells based on target cell number per file and file count. New file is started every time the target number of KVs is reached, unless the fixed count of writers has already been created (in that case all the remaining KVs go into the last writer).
