ramkrishna.s.vasudevan commented on HBASE-12669:
------------------------------------------------
The approach looks good to me using the scan type to track the delete trackers.
This would not need any change in the scanquery matcher too. Not committing
the del writer file if there are no del trackers seems a good option too.
> Have compaction scanner save info about delete markers

> for the native mob compaction, we will need a scanner pass used the major
> compaction that records the delete markers in the mob-enabled columns. This
> would implement that core section.
