Cassandra is last writer wins... according to the client timestamp? What the fucking fuck? (via @fowlduck)
@therealadam orly! eeeenteresting. I'm still confused why they don't use a server timestamp instead of a client one

@bascule@therealadam so the timestamp doesn’t have to be the current time only, it could be in reference to when an event occurred -
@fowlduck@therealadam given how weak a guarantee last writer wins provides for reconciling distributed causality, I don't see the advantage -
@bascule each “sibling” would go in a column -
@therealadam I don't understand how that would work, but it sounds something like what I want

@bascule@therealadam which server time stamp? Also, it needn't be time, but rather version/monotonic increasing. -
@jdunck@therealadam yes, it can be a scalar (non-time-based) clock, but scalar clocks have problems too, just ask@zooko

@bascule you’d still have to fight clock skew? CDRTs are the better answer, IMO.Thanks. Twitter will use this to make your timeline better. UndoUndo
