> In some use cases, you can safely remove the tombstones of an expired column.
> In theory, this is true in each case where you know that you will never
> update a column
> using a ttl strictly lesser that the one of the old column.
> This will be the case for instance if you always use the same ttl on all the
> columns of a CF
> (say you use the CF for a long term persistent cache).
> I propose adding an option (by CF) that says 'always remove tombstone of
> expired columns
> for that CF'.
