Transcript

  • 1. NoSQL workshop Friso van Vollenhoven fvanvollenhoven@xebia.com Joris BontjeDiscover the diversity of jbontje@xebia.comNoSQL
  • 2. Why not only SQL? RDBMS RDBMS RDBMS RDBMS RDBMS not scaling out per scaling up built with scale machine licenses has limits out in mind is expensive
  • 3. Why not only SQL?
  • 4. NoSQL landscape
  • 5. MongoDB‣ Document-oriented database (schema free)‣ Adhoc queries, querying nested fields, indexing‣ Sharding and Replication$ db.twitter-user.find({id: 14352528}){! name: “NLJUG, Dutch Java Us”! statuses_count: 200! description: ”NLJUG”! location: ”Netherlands”! screen_name: ”nljug”! status: {! ! id: 126973661537255420! ! geo: null! ! source: ”HootSuite”! ! text: ”RT @ktukker: en het lijkt erop dat het kabeltje weer verbonden is. de! ! @nljug server is weer bereikbaar. #xs4all #storing”! ! created_at: ”Thu Oct 20 10:50:54 +0000 2011”! }! url: ”http://www.nljug.org/”! friends_count: 31! followers_count: 950! id: 14352528! created_at: ”Thu Apr 10 16:12:07 +0000 2008”}
  • 6. Neo4j‣ Graph database‣ Storing data as nodes and relationships in graphs‣ High-speed node traversal / search‣ Full transaction support‣ Scalable for reads through replication
  • 7. HBase‣ Sparse column database‣ Based on Google’s BigTable model (similar to Cassandra)‣ Built for scalability‣ Strong consistency at the row level‣ Data model: ‣ row key => column family:column qualifier:column value ‣ columns are sparse ‣ Data is always byte[] key / column family ‘DATA FAMILY’ ‘OTHER FAMILY’ [100, 101, 13, 8] [13,10]:[1,2,3,4,5] [18,10]:[1,9,7] [120,124]:[123] [100, 101, 13, 10] [13,10]:[1,2,3,4,5] [20,9]:[1,9,7] [120,124]:[123] [100, 101, 13, 22] [18,10]:[1,9,7] [120,124]:[123]
  • 8. Riak‣ Decentralized Key-value store‣ Links, MapReduce, Secondary indexes‣ No master node; no single point of failure‣ Eventually consistentGET /riak/twitter-user/14352528Content-Type: application/json{! name: “NLJUG, Dutch Java Us”! statuses_count: 200! description: ”NLJUG”! location: ”Netherlands”! screen_name: ”nljug”! status: {! ! id: 126973661537255420! ! geo: null! ! source: ”HootSuite”! ! text: ”RT @ktukker: en het lijkt erop dat het kabeltje weer verbonden is. de! ! @nljug server is weer bereikbaar. #xs4all #storing”! ! created_at: ”Thu Oct 20 10:50:54 +0000 2011”! }! url: ”http://www.nljug.org/”! friends_count: 31! followers_count: 950! id: 14352528! created_at: ”Thu Apr 10 16:12:07 +0000 2008”}
  • 9. Exercise‣ Twitter data: ‣ Most @nljug followers and their most recent tweets as JSON data‣ Now create 4 groups: ‣ MongoDB: Age ‣ Neo4j: Ron ‣ HBase: Friso ‣ Riak: Joris‣ Access Point: NOSQL password: jfall2011‣ Data and source available on http://192.168.0.100:8080/‣ Check README.md for installation instructions, exercises and hints
