Hi, I've seen a couple of people on Stack Overflow having problems with performance when they have maps that they continuously update, and in hindsight I think I might have run into the same problem myself (but I didn't suspect it as the reason and designed differently and by accident didn't use maps anymore).
Is there any reason that maps (or lists or sets) in particular would become a performance issue when they're heavily modified? As I've understood them they're not special, and shouldn't be any different performance wise than overwriting regular columns. Is there something different going on that I'm missing? Here are the Stack Overflow questions: http://stackoverflow.com/questions/17282837/cassandra-insert-perfomance-issue-into-a-table-with-a-map-type/17290981 http://stackoverflow.com/questions/17082963/bad-performance-when-writing-log-data-to-cassandra-with-timeuuid-as-a-column-nam/17123236 yours, Theo
