    });

37. riak.walk('users', 'roidrage', [['users', '_', 'bromance']])

38. map reduce

39. riak.mapreduce.add('users'). map('Riak.mapValuesJson'). run()

40. riak.mapreduce.add('users'). map(function(obj) { return [obj.values[0]]; }). run()

41. javascript!

42. riak.mapreduce.add('users'). map(function(v) { return [v.values[0].name]; }). reduce('Riak.reduceSort'). run()

55. metrics

56. riak.registerListener({ 'riak.request.end': function(event) { var duration = event.finished_at - event.started_at,

    name = 'riak.request.' + event.method.toLowerCase(); metrics.timing(name, runtime); } });
