@Internal
public interface CompactingFileWriter

The file sink compactors use the CompactingFileWriter to write a compacting file.

A class should not directly implement the CompactingFileWriter, but to implement the RecordWiseCompactingFileWriter, or the OutputStreamBasedCompactingFileWriter, or both. If an class implements both interfaces, once the write method of either interface is called, the write method in the other one should be disabled.
