Anoop Sam John commented on HBASE-12296:
----------------------------------------

It is an Incompatible change for custom filters IF they were directly 
implementing Filter interface.  But if those were extending FilterBase, we have 
made it compatible.   JFR

> Filters should work with ByteBufferedCell

> Now we have added an extension for Cell in server side, ByteBufferedCell, 
> where Cells are backed by BB (on heap or off heap). When the Cell is backed 
> by off heap buffer, the getXXXArray() APIs has to create temp byte[] and do 
> data copy and return that. This will be bit costly.  We have avoided this in 
> areas like CellComparator/SQM etc. Filter area was not touched in that patch. 
>  This Jira aims at doing it in Filter area. 
> Eg : SCVF checking the cell value for the given value condition. It uses 
> getValueArray() to get cell value bytes.  When the cell is BB backed, it has 
> to use getValueByteBuffer() API instead.
