> Currently when using ByteArrayCodec the defrag internally creates a copy of
> the buffer by allocating a new byte array for each and every key. This can be
> avoided if we directly use CodecBuffer provided by the table. The patch
> creates a new CodecBufferCodec for avoid unnecessary creation of objects. The
> patch also adds sufficient amount of unit tests to test each function of the
> defrag service
