Problem solved
FlockDB was created to address the significant scalability and performance limitations of traditional relational databases when storing and querying Twitter's massive social graph (e.g., follower/following relationships). It provided a highly scalable, fault-tolerant solution for adjacency list lookups that existing databases could not handle efficiently at billions of edges and high fan-out scenarios.
