flockdb: All content tagged as flockdb in NoSQL databases and polyglot persistence
The main page of InfiniteGraph, a graph database commercialized by Objectivity, features an interesting comparison of 7 graph databases (InfiniteGraph, Neo4j, AllegroGraph, Titan, FlockDB, Dex, OrientDB) based on 16 criteria: licensing, source, scalability, graph model, schema model, API, query method, platforms, consistency, concurrency (distributed processing), partitioning, extensibility, visualizing tools, storage back end/persistency, language, backup/restore.
Unfortunately the image is almost unreadable, but Peter Karussell has extracted the data in a GoogleDoc spreadsheet embedded below.

Three presentations covering the various NoSQL usages at Twitter:
Kevin Weil talking about data analysis using Scribe for logging, base analysis with Pig/Hadoop, and specialized data analysis with HBase, Cassandra, and FlockDB on InfoQ
Ryan King’s presentation from last year’s QCon SF NoSQL track on Gizzard, Cassandra, Hadoop, and Redis on InfoQ
Dmitriy Ryaboy on Hadoop from Devoxx 2010:
- Twitter: Cassandra, HBase, Hadoop, Scribe, FlockDB, Redis
- Facebook: Cassandra, HBase, Hadoop, Scribe, Hive
- Netflix: Amazon SimpleDB, Cassandra
- Digg: Cassandra
- SimpleGeo: Cassandra
- StumbleUpon: HBase, OpenTSDB
- Yahoo!: Hadoop, HBase, PNUTS
- Rackspace: Cassandra
And probably many more missing from the list. But that could change if you leave a comment.
