25. riak = require('riak-js').getClient()
26. riak.get('users', 'roidrage')
27. user = {name: 'Mathias Meyer'} riak.save('users', 'roidrage', user)
28. riak.get('users', 'roidrage', function(error, data) { console.log(data); } )
29. riak.get('users', 'roidrage', function(error, data) { if (error.notFound) { console.log('User doesn't exist!'); } } )
30. meta
31. riak.get('users', 'roidrage', {r: 1});
32. riak.get('users', 'roidrage', function(error, data, meta) { console.log(meta.vclock); } )
33. reusable
34. riak.get('users', 'roidrage', function(error, user, meta) { user.city = 'Berlin'; riak.save('users', 'roidrage', user, meta); } )
35. links
36. riak.save('users', 'roidrage', user, {links: [{bucket: 'users', key: 'tsantero', tag: 'bromance'}] });
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()
43. search
44. riak.saveBucket('users', {search: true})
45. riak.save('users', 'roidrage', {name: 'Mathias Meyer'});
46. riak.search.find('users', 'name:Mathias*')
47. search — map reduce

49. secondary indexes
50. riak.save('users', 'roidrage', {name: 'Mathias Meyer'}, {index: {name: 'Mathias Meyer', born: 1977}});
51. riak.query('users', {born: 1977})
52. riak.query('users', {born: [1977, 1980]})
53. instrumentation
54. riak.registerListener({ 'riak.request.end': function(event) {}, 'riak.request.start': function(event) {} });
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); } });
