When combined with the caching proxy, the high performance of the Riak cluster itself, and proper caching settings on the client side, we have a powerful infrastructure on which to build highly scalable applications. More over, we haven’t even touched the incredibly cool things one can do with search and map/reduce on the Riak cluster, or building complex mappings using the links and key filters.
More or less all web accessible NoSQL databases can benefit from a caching proxy. On the other hand, I’d say that it’s worth having an (even basic) internal cache for scenarios where the working data set is smaller than the total amount of data stored.
