Datastore Internals Based on Bigtable – high scalability – High availability synchronous writes on multiple datacenters 23 Source: Datastore Introduction, http://www.youtube.com/watch?v=fQazhzcC-rghttp://www.youtube.com/watch?v=fQazhzcC-rg Datastore Megastore Bigtable query transactions Scalable and reliable storage

24. What is Bigtable? Scalable, distributed, highly-available and structured storage – Bigtable is not database by itself (it doesn’t support query) Google usage – In production since April 2005 – Web Search, YouTube, Earth, Analytics 24 Source: Datastore Introduction, http://www.youtube.com/watch?v=fQazhzcC-rghttp://www.youtube.com/watch?v=fQazhzcC-rg Bigtable Scalable and reliable storage

25. Bigtable Data Model A row has a Key and Columns Sorted by Key – In lexical order – Enables range query by application 25 Source: Datastore Introduction, http://www.youtube.com/watch?v=fQazhzcC-rghttp://www.youtube.com/watch?v=fQazhzcC-rg “ …” “CNN” “CNN.com” “com.cnn.www” “contents:”“anchor:cnnsi.com” “anchor:my.look.ca” “ …” t6t6 t5t5 t3t3 t9t9 t8t8
