-----------------------------------
Summary: Marker interface for Cells which may have backing
ByteBuffers
Key: HBASE-28670
URL: https://issues.apache.org/jira/browse/HBASE-28670
Project: HBase
Issue Type: Improvement
Reporter: Istvan Toth
We often need to treat cells that may have backing ByteBuffers.
The easy thing to would be checking if they are ByteBufferExtendedCell , but
CellWrapper , OnHepDecodedCell and TagRewriteCell may also delegate to a
ByteBufferExtendedCell.
Having a marker interface that indicates that a cell is guaranteed to be
on-heap, or that it may not be fully on-heap would make it easier and faster
check whether we need to clone them. (We only need one, it may be either
negative or positive)
