FlockDB is a distributed, fault-tolerant graph database built by Twitter for storing adjacency lists of directed graphs, such as social graphs. It is optimized for high-throughput, low-latency online workloads with simple edge storage and set arithmetic queries rather than multi-hop graph traversal.

Use cases

• store a social graph like who follows whom
• run set arithmetic queries over large edge lists
• page through query results containing millions of edges
• archive and later restore graph edges
• horizontally scale a high write-throughput graph store
• store secondary indices for a large web service

When to choose

• you need simple adjacency-list storage with very high read/write throughput
• you want horizontal scaling and replication for billions of edges
• your queries are single-hop set operations rather than graph walks

When to avoid

• you need multi-hop or graph-walking queries, which are explicitly non-goals
• you want an actively maintained project - Twitter no longer maintains it or responds to issues
• you need automatic shard migrations or a general-purpose graph database like Neo4j
