Just to slightly augment what was already posted by Aaron; deletes are not special in terms of the chosen consistency level. If you submit a mutation with a QUOROM consistency level for example, that QUOROM consistency requirement applies equally to deletes as it does to inserts. (That said, deletes are a bit special in other ways to go GCGraceSeconds, but that is another story.) -- / Peter Schuller
