Release: Riak 0.8 supports JavaScript MapReduce
Less than a week after the Riak 0.7.1 release, Basho guys launched a new version that brings an extremely exciting new feature: JavaScript MapReduce support.
The ☞ official blog post mentions that the current JavaScript engine used is Mozilla’s Spidermonkey through erlang_js.
The Javascript map/reduce functions can be defined and used from the Erlang shell or directly over HTTP. Riak 0.8.0 also ships with a couple of map/reduce functions. You’ll probably find more details and examples in the ☞ documentation.
As they already used us since the Riak with embedded Erlang, the guys went the extra step and prepared a 15 min video introducing the JavaScript MapReduce support so you can get up to speed with it right away:
