A story of using Riak for its Dynamo-like building blocks:

I made use of riak-kv, riak-search, and riak-core to help distribute my application’s data, state, and processing, respectively. These technologies provided me with a framework I could use instead of trying to build the functionality myself. This allowed me to put the entire application behind a dumb splitter and call it a day. A horizontal scale out is a simple matter of standing up a new node, joining it to the cluster, and adding an entry to the splitter.

The usage of riak-search as a distributed file index is interesting, given there’s also Luwak — but that Riak library is meant for large files.

As the author mentions this is an internal application of AOL Advertising. The public facing AOL Advertising is using Membase and Hadoop.
