Aaron Staple's presentation at the Silicon Valley iPhone and iPad Developers' Meetup on July 19: http://www.meetup.com/sviphone/calendar/13248809/

1. open-source, high-performance, document-oriented database Aaron Staple [email_address]

2. Version 1.6 comes out in 2 weeks

3. Production Examples

4. RDBMS (Oracle, MySQL) New Gen. OLAP (vertica, aster, greenplum) Non-relational Operational Stores (“NoSQL”)

6. Horizontally Scalable Architectures no joins no complex transactions +

7. New Data Models no joins no complex transactions +

8. New Data Models more natural ways to develop applications?

9. JSON-style Documents { “hello” : “world” } 16000000 02 hello00 06000000world00 00 http://bsonspec.org represented as BSON

10. Flexible “Schemas” {“author”: “mike”, “ links”: 3 , “ date”: "Sun Jul 18 2010 14:40:20 GMT-0700 (PDT)" “ text”: “...”}

12. Dynamic Queries

13. Posts by Author db.posts.find({author: “mike”})

14. Last 10 Posts db.posts.find() .sort({date: -1}) .limit(10)

15. Posts Since April 1 april_1 = new Date(2010, 3, 1) db.posts.find({date: {$gt: april_1}})

16. Index any combination of fields, including embedded fields

17. Indexes {“author”: “mike”, “ links”: 3 , “ date”: "Sun Jul 18 2010 14:40:20 GMT-0700 (PDT)" “ text”: “...”} db.posts.ensureIndex({links: 1})

18. Indexes {author: “mike”, … , comments: [ {author: “eliot”, date: new Date(), text: “great post!”} }, … ] } db.posts.ensureIndex({‘comments.author’: 1, ‘ comments.date’: -1 })

19. Advanced Queries and Map/Reduce Support

20. Posts Ending With ‘Tech’ db.posts.find({text: /Tech$/})

22. Variety of Operators db.posts.find( {$or: [{a:1}, {b:{$mod:[5,2]}} ]})

23. Map/Reduce > m = function() { emit(this.user_id, 1); } > r = function(k,vals) { return 1; } > res = db.events.mapReduce(m, r, { query : {type:'sale'} }); > db[res.result].find().limit(2) { "_id" : 8321073716060 , "value" : 1 } { "_id" : 7921232311289 , "value" : 1 }

24. Atomic Updates, Unique Key Constraints

25. Embedding a Comment c = {author: “eliot”, date: new Date(), text: “great post!”} db.posts.update({_id: post._id}, {$push: {comments: c}})

26. Many Supported Platforms / Languages with Native Drivers

27. Focus on Performance

29. Replication and Replica Sets I II III master slave slave master slave master slave master slave

30. Auto Sharding client mongos ... mongos mongod ... Shards mongod mongod mongod Config Servers mongod mongod mongod mongod mongod mongod mongod mongod ...

33. Features you guys care about

34. Geospatial Indexing db.places.ensureIndex( { loc : "2d" } ) db.places.find( { loc : { $near :[50,50] } } ).limit(20)

35. Geospatial Indexing db.places.ensureIndex( { location : "2d" , category : 1 } ); db.places.find( { location : { $near : [50,50] }, category : 'coffee' } );
