Transcript

  • 1. open-source, high-performance, schema-free, document-oriented database http://www.mongodb.org/
  • 2. “One size fits all” no longer RDBMS (Oracle, MySQL) Non-relational New gen. OLAP (vertica, aster, greenplum) operational stores (“NoSQL”)
  • 3. NoSQL really means: non-relational next generation operational datastores and databases
  • 4. Scaling out no joins + light transactional semantics = horizontally scalable architectures
  • 5. Data models no joins + light transactional semantics = horizontally scalable architectures important side effect : new data models = improved ways to develop applications
  • 6. Documents and BSON {“hello”: “world”} {“hello”: “world”, “foo”: [{“bar”: 1}]}
  • 7. Schema-free collections • Dynamically typed languages • Migrations • Still define indexes per collection
  • 8. Dynamic queries • Administration • Ease of development / familiarity db.coll.find({“hello”: “world”}) db.coll.find({“foo”: {“$gt”: 50}}) db.coll.find().limit(20).sort({“x”: 1})
  • 9. Atomic update modifiers db.coll.update({“hello”: “world”}, {“$set”: {“foo”: “bar”}}) db.coll.update({}, {“$push”: {“x”: 1}}, multi=True) db.coll.update({“x”: 1}, {“$inc”: {“y”: 5}}, upsert=True)
  • 10. Focus on performance
  • 11. Replication • Master-slave • Replica pairs (sets)
  • 12. Auto-sharding
  • 13. Many supported languages and platforms
  • 14. Other cool stuff • Aggregation and map reduce • Capped collections • Unique indexes • Mongo shell • GridFS
  • 15. 1. Download MongoDB http://www.mongodb.org 2. Try it out! 3. Let us know what you think.
  • 16. NoSQL Live from Boston Thursday, March 11 http://www.10gen.com/events
  • 17. • http://www.mongodb.org • irc.freenode.net#mongodb • mongodb-user on google groups • @mongodb, @mdirolf • mike@10gen.com
