Anoop Sam John commented on HBASE-13387:
----------------------------------------
This will be a big patch. So I am planning to split into multiple tasks and
make core code ready for accepting BB backed cells.
- Make Tag as an interface impl way
- Deperecate filterRowKey(byte[] buffer, int offset, int length) in favor of
filterRowKey(Cell firstRowCell)
- Deprecate postScannerFilterRow CP hook with byte[],int,int args in favor of
taking Cell arg
- Change ColumnTracker methods to pass Cell instead of byte[], int, int for
column.
- Remove CellComparator#compareRows(byte[], int, int, byte[], int,int)
- CellUtil - More typed getters from Cell components (Like getRowAsInt,
getValueAsLong etc)
.....
> Add ByteBufferedCell an extension to Cell

> This came in btw the discussion abt the parent Jira and recently Stack added
> as a comment on the E2E patch on the parent Jira.
> The idea is to add a new Interface 'ByteBufferedCell' in which we can add
> new buffer based getter APIs and getters for position in components in BB.
> We will keep this interface @InterfaceAudience.Private. When the Cell is
> backed by a DBB, we can create an Object implementing this new interface.
> The Comparators has to be aware abt this new Cell extension and has to use
> the BB based APIs rather than getXXXArray(). Also give util APIs in CellUtil
> to abstract the checks for new Cell type. (Like matchingXXX APIs,
> getValueAs<type> APIs etc)
