Class StripeMultiFileWriter.BoundaryMultiWriter

java.lang.Object

org.apache.hadoop.hbase.regionserver.AbstractMultiFileWriter

org.apache.hadoop.hbase.regionserver.StripeMultiFileWriter

org.apache.hadoop.hbase.regionserver.StripeMultiFileWriter.BoundaryMultiWriter

All Implemented Interfaces:

Compactor.CellSink

Enclosing class:

StripeMultiFileWriter

public static class StripeMultiFileWriter.BoundaryMultiWriter
extends StripeMultiFileWriter

MultiWriter that separates the cells based on fixed row-key boundaries. All the KVs between each pair of neighboring boundaries from the list supplied to ctor will end up in one file, and separate from all other such pairs.

Constructor Detail

BoundaryMultiWriter

public BoundaryMultiWriter(KeyValue.KVComparator comparator,
                           java.util.List<byte[]> targetBoundaries,
                           byte[] majorRangeFrom,
                           byte[] majorRangeTo)
                    throws java.io.IOException

Parameters:

targetBoundaries - The boundaries on which writers/files are separated.

majorRangeFrom - Major range is the range for which at least one file should be written (because all files are included in compaction). majorRangeFrom is the left boundary.

majorRangeTo - The right boundary of majorRange (see majorRangeFrom).

Throws:

java.io.IOException
