ramkrishna.s.vasudevan updated HBASE-10885:
-------------------------------------------
Attachment: HBASE-10885_v9.patch
Latest patch. There is one change in the Visibility Delete Tracker where
multiple family delete are handled by tracking those time stamps and also
multiple delete columns are also handled. I think this covers all the cases
and the cases have been verified running the IT test case that will be attached
in HBASE-11039.

> Accumulo can specify visibility expressions for delete markers. During
> compaction the cells covered by the tombstone are determined in part by
> matching the visibility expression. This is useful for the use case of data
> set coalescing, where entries from multiple data sets carrying different
> labels are combined into one common large table. Later, a subset of entries
> can be conveniently removed using visibility expressions.
> Currently doing the same in HBase would only be possible with a custom
> coprocessor. Otherwise, a Delete will affect all cells covered by the
> tombstone regardless of any visibility expression scoping. This is correct
> behavior in that no data spill is possible, but certainly could be
> surprising, and is only meant to be transitional. We decided not to support
> visibility expressions on Deletes to control the complexity of the initial
> implementation.
