The official docs say that dropped mutations are only fixed by Read Repair and Anti-entropy (http://wiki.apache.org/cassandra/FAQ#dropped_messages). However, in this thread ( http://grokbase.com/t/cassandra/user/1235ctdbca/mutation-dropped-messages) Aaron Morton says that Hinted Handoff also repairs dropped mutations, but I couldn't find more info on that. Is this still the behavior on 1.2+?
To illustrate: If I write with RF=2, CL=ONE: one mutation is accepted, the write returns and the other mutation is dropped. Does the coordinator store a hint of the dropped replica? Even without running repair, will I be able to read that write from the dropped replica in 30 minutes?
