Deleted cells are still subject to TTL and there will never be more than
maximum number of versions deleted cells. A new raw scan options returns
all deleted rows and the delete markers.
This is different from
correct as-of-time queries when it comes to deletes.

Lars,
No, that is not what I am suggesting.
Perhaps I am missing something. Was the OP interested in cells or in row
deletes.?
Two different issues.

I would suggest that you use your coprocessor to copy the data to a 'backup'
table when you mark them for delete.
Then as major compaction hits, the rows are deleted from the main table

(It might well be, just curious)
Ok... so what exactly does this feature mean?
Suppose I have 500 rows within a region

Hi, All,
I want to retain all deleted key-value pairs in hbase. I have tried to
config HColumnDescript as follow to make it return deleted

still reside undeleted in your delete table.
Call it a history table.

+1 for this solution.
A history table can solve this with less troubles
