Ebot, Could you share a bit more about what you are trying to achieve? CQL3 does have an analogy to dynamic columns<http://www.datastax.com/dev/blog/does-cql-support-dynamic-columns-wide-rows>, and you could potentially use collections (if your data isn't too large).
Hard to say more without details. Cheers, -- Patricia Gorla @patriciagorla Consultant Apache Cassandra Consulting http://www.thelastpickle.com <http://thelastpickle.com>
