3. Row prefix delete operation - Delete all rows which starts with a 'prefix'
This is interesting.
Worth considering a Delete API that takes a Scan (or equivalent*) as argument?
* - Possibly pulling up the start row, stop row, filter chain fields
of Scan into a more generic object that can be passed to such an API
and extended by Scan, if the use of Scan in an API like Delete leads
in consensus opinion to a mixed metaphor.
We have a use case where we need to delete columns but we don't know
their rows. We run a Scan on a range of rows and custom-filter the rows
containg the columns to be deleted. Then we delete all the columns from
the Scan result. This is a 2 step operation and it implies networks
traffic. We've started to implement a coprocessor to move the Scan and
Delete at RS level but, if the API above can delete also columns and not
entire rows then it will be welcomed :)
