FlockDB differs from other graph databases, e.g. Neo4j in that it is not designed for multi-hop graph traversal but rather for rapid set operations, not unlike the primary use-case for Redis sets.[4] Since it is still in the process of being packaged for outside of Twitter use, the code is still very rough and hence there is no stable release available yet. FlockDB was posted on GitHub shortly after Twitter released its Gizzard framework, which it uses to query the FlockDB distributed datastore. The database is licensed under the Apache License.[1] See also{{Portal|Free and open-source software}}
