Subject Re: vector clocks?
Date Mon, 07 Dec 2009 14:45:10 GMT
So, currently, is Cassandra using the client provided timestamps for
conflict resolution? (Or something else?)
Do clients have insight to conflicts Cassandra cannot resolve (assuming it
tries to resolve them)?
What's the semantic of "eventual consistency" in Cassandra's case then?
