Introductiion à NoSQL dans le cadre des Last Thursday strasbourgeois http://www.facebook.com/home.php#!/group.php?gid=44635341639&ref=ts

1. NoSQL

2. Non-relational data stores Eric Evans, Rackspace, early 2009

3. Not only SQL No to SQL

5. Giving up ACID Eventual consistency Schemaless Scale horizontally

6. ACID Atomicity Consistency Isolation Durability

7. BASE Basically Available Soft state Eventually consistent

8. 1. Key Value stores

9. Redis C in memory journal append-only file list/set/sorted set boolean operation

10. Erlang similar to Redis in memory EU sponsored Scalaris

11. Mixi (Facebook japonais) Tokyo Tyrant (client) Tokyo Cabinet (server) several server mecanism asynchronous replication multi-master, master/slave map/reduce in Lua API compatibility w Memcached in memory or disk Tokyo Tyrant

12. Java LinkedIn in memory pluggable storage Project Voldemort

13. Erlang REST JSON in memory or disk Riak

14. 2. Document stores

15. Amazon Web Services proprietary pay as you go SimpleDB

16. Erlang Apache map/reduce in Javascript REST JSON CouchDB

17. C++ 10gen query & map/reduce in Javascript socket BSON (Binary JSON) automatic sharding GridFS master/slave asynchronous replication MongoDB

18. 3. Extensible record stores

19. ” Bigtable: A Distributed Storage System for Structured Data”

20. Java Apache BigTable w Hadoop (DFS) HBase

21. C++ Zvents, Baidu very similar to Hbase needs DFS (like Hadoop) HQL HyperTable

22. Java Facebook then Apache very similar to Hbase marriage of Dynamo and BigTable supercolumn, column tunable concistency decentralized fault tolerant (data center) elasticity Cassandra

23. For who ?

24. ” If you're asking me, should I use a NoSQL store ? Then the answer is no.”

25. !CouchDB MongoDB Redis (?) Our choice @novelys

26. pretty straightforward pretty close from our previous DB drivers developped in parallel several ODM in Ruby schema-less ! easy querying no fulltext search (well not really) rethinking how we store data kind of builtin denormalization Experience w Mongo http://www.rocketblogging.com
