Riak also supports, in addition to HTTP, Protocol Buffers - a binary encoding protocol introduced by Google.

A few other notable Riak features include a JS or Erlang MapReduce API and full-text search.

Thanks, amended RIAK with Erlang map/reduce and full-text search! (I need to read up on Protocol Buffers, but it sounds useful, too).
