Enis Soztutar commented on HBASE-10719:
---------------------------------------
Had a chat with [~mcorgan] about this when Cell was first introduced. He was
saying that ByteBuffer is an abstract class and have a lot more overhead than
byte[]. Our own ByteRange does not have this.
> Cell interface may need a ByteBuffer rather than a byte[]

> The byte[] backing a cell may be off heap also. In such a case having a
> byte[] may require a copy offheap to on heap. So better to have ByteBuffer
> backing a Cell.
