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
- StripeMultiFileWriter.BoundaryMultiWriter
```
public StripeMultiFileWriter.BoundaryMultiWriter(KeyValue.KVComparator comparator,
                                         List<byte[]> targetBoundaries,
                                         byte[] majorRangeFrom,
                                         byte[] majorRangeTo)
                                          throws 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:
  
  IOException
