> This is a follow-up on CASSANDRA-4545. We've made batch be atomic by default,
> however it is actually possible for normal inserts to not be atomic by
> default thanks to the support of the IN notation.
> I don't think this is very coherent so I suggest the two following changes:
> * make sure normal inserts/deletes are always atomic ("logged")
> * make sure we use mutate (rather than mutateAtomically) if there is only one
> mutation (i.e. use the batch log in normal inserts/deletes only if there is
> an IN).
> And if people really want to do "unlogged" insert with IN, they can put the
> insert inside an unlogged batch.
