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...

You might find this of interest as well (as seen on G+ Node.js' page): http://nodeup.com/eleven

It's a podcast about various databases, both SQL and noSQL, in relation to Node.js.
