    In case you are talking about Cassandra collections (maps and sets), and not abstract maps/sets, then you are wrong. Only CQL3 Lists work like that - there are no UUIDs anywhere in…

    Performance, mostly. To read both the email and the phone you'll have to make two requests (or a single multiget). The keys have a good chance of belonging to different replicas, t…
