Anoop Sam John commented on HBASE-12282:
----------------------------------------
Yep.
When we have seeks we pass the SeekKey backed into a KeyOnlyKV now. May be that
also we can pass in as BB backed Cell. So in the Compare path we have BB
Backed Cells alone. But the comparator need to make sure it can work with
buffer backed also (?) There is a bit challenge to make it perfect design.
> 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.
