Anoop Sam John commented on HBASE-12282:
----------------------------------------
I think Stack suggestion is to
add hasArray() in Cell
We have new BBBackedCell which extending Cell.
In impl of BB backed let hasArray() return false.
In comparators, based on hasArray() use getxxxArray() or getxxxBuffer()
Correct Stack?
> 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.
