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:

Compactor.CellSink

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).
