> This is in path towards HBASE-13387
> When the scan contains any filter, we have to call the
> filterRowKey(byte[],int,int) API. (Even if it is not interested in this
> method)
> When the Cells coming in is offheap backed, we would need temp byte[]
> creation and copy row bytes to that. If we can make this Filter API to take
> a cell (which is the first cell in any row), we can avoid this overhead.
> In 2.0.0 we will deprecate the old API with addition of new and FilterBase
> will give BC for old style custom Filters.
