> Currently cassandra supports "read repair," i.e., lazy repair when a read is done. This is better than nothing but is not sufficient for some cases (e.g. catastrophic node failure where you need to rebuild all of a node's data on a new machine).
> Dynamo uses merkle trees here. This is harder for Cassandra given the CF data model but I suppose we could just hash the serialized CF value.
