Subject Re: Realtime data and (C)AP

Your options are

1. Read & write at quorum
2. Recognize that, in general, if you've got a real need for Cassandra,
your data is out of date almost immediately after you've read it no matter
what guarantee your DB gives you, so you might as well just forget about
ever getting the "right" answer because you probably can't even define what
that is.
