类 StripeMultiFileWriter.SizeMultiWriter

java.lang.Object

org.apache.hadoop.hbase.regionserver.AbstractMultiFileWriter

org.apache.hadoop.hbase.regionserver.StripeMultiFileWriter

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

所有已实现的接口:

Compactor.CellSink

封闭类:

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).

StripeMultiFileWriter.SizeMultiWriter

public StripeMultiFileWriter.SizeMultiWriter(KeyValue.KVComparator comparator,
                                     int targetCount,
                                     long targetKvs,

                                     byte[] right)

参数:

targetCount - The maximum count of writers that can be created.

targetKvs - The number of KVs to read from source before starting each new writer.

left - The left boundary of the first writer.

right - The right boundary of the last writer.
