HintedHandoff - Cassandra WikiIf a write is made and a replica node for the key is down (and hinted_handoff_enabled == true), Cassandra will write a hint to: versions prior to 1.0: a live replica node version 1.0: the coordinator node indicating that the write needs to be replayed to the unavailable node. If ConsistencyLevel.ANY was specified, the hint will count towards consistency if no replica nodes are alive for this key.
