Sylvain Lebresne commented on CASSANDRA-3448:
---------------------------------------------
The linked, duplicate, issue is CASSANDRA-494 which is marked as 'Later'
meaning that it's not supported yet but is not scheduled for the near future
either. The reasons for that are in the comments of the aforementioned ticket
but to sum it up: it requires important changes internally and the interest in
that feature hasn't been high enough to match it so far. You are free to give
your opinion on the matter of course, the 'marked as a duplicate' was just a
way to say that the discussion probably belongs to CASSANDRA-494 to avoid
dispersion.

> I'd like to be able to delete a range of columns within a row, for a range of
> column names. Currently it seems my only option is to do a range query and
> then individually delete each column. For wide rows, this is very slow, even
> with batch mutation.
> The thrift API looks like it supports the call, however it throws the
> following error message: "Deletion does not yet
> support SliceRange predicates.". I'm talking specifically about batch_mutate
> + Mutation(Deletion(SlicePredicate(SliceRange(start, end))).
