Jonathan Ellis commented on CASSANDRA-193:
------------------------------------------
That's true. That's a logical division.
I'm still a little scared by the performance implications of basically doing
mini read-only compactions to keep the tree accurate. I'm going to mark this
as requiring CASSANDRA-234.

> 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.
