Anoop Sam John commented on HBASE-12282:
----------------------------------------
bq.KV backed by buffer and byte[].
IMO no need to have single Cell impl having both data structures. It is the
responsibility of the comparators etc to get correctly the data.
> Ensure Cells and its implementations work with Buffers also

> This issue can be used to brainstorm and then do the necessary changes for
> the offheap work. All impl of cells deal with byte[] but when we change the
> Hfileblocks/Readers to work purely with Buffers then the byte[] usage would
> mean that always the data is copied to the onheap. Cell may need some
> interface change to implement this.
