Jingcheng Du commented on HBASE-11861:
--------------------------------------
Hi Jon [~jmhsieh], please ignore my last comment about the new KeyValue.Type. I
think we could directly add a new API for the MobStoreScanner to add a new
argument for the deleted cells, the API looks like
{code}
public boolean next(List<Cell> outResult, List<Cell> deletedCell, int limit)
throws IOException {
{code}
> Native MOB Compaction mechanisms.

> URL: https://issues.apache.org/jira/browse/HBASE-11861
> Project: HBase
> Issue Type: Sub-task
> Components: regionserver, Scanners
> Affects Versions: 2.0.0
> Reporter: Jonathan Hsieh

>
> Currently, the first cut of mob will have external processes to age off old
> mob data (the ttl cleaner), and to compact away deleted or over written data
> (the sweep tool).
> From an operational point of view, having two external tools, especially one
> that relies on MapReduce is undesirable. In this issue we'll tackle
> integrating these into hbase without requiring external processes.
