Constructor Detail

BoundaryMultiWriter

public BoundaryMultiWriter(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
