> Cassandra (similar to other Dynamo systems) offers great primary key-based access operations (e.g. get, put, delete), but doesn’t scale well for secondary-index lookups
Riak does have secondary-index lookups. I wonder how those scale compared to Cassandra's.
It's basically the same design (both are good at indexing low-cardinality data, and poor for high-), except that Cassandra allows non-index predicates to also be filtered server-side during an index scan: http://www.datastax.com/dev/blog/whats-new-cassandra-07-seco...
