Anoop Sam John updated HBASE-12296:
-----------------------------------
Description:
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.
was:Filters may require API changes to work with BBs.
> Filters should work with ByteBufferedCell
