I'm asking because the DataStax DS-201 course states that C* is an ideal fit for messaging applications.
What I'm not understanding? :-)
Messaging applications generally must be totally consistent, expecially real-time ones.

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 Recognize that, in general, if you've got a real need for Cassandra, your data is out of date almost immediately after you've read it no matter what guarantee your DB gives you, so you might as well just forget about ever getting the "right" answer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.

    How the two things can fit together?
    Cassandra endorses the AP side of the CAP theorem. So how
    Cassandra can
    deliver realtime consistent data?
    AFAIK, choosing a consistency level equals to ALL can be a huge
    performance hit for C*, so, please, explain me why I should choose C*
    for realtime data
    that should be consistent across reads after the data has been
    written.

    Thank you.
