FlockDB
DESCRIPTION
FlockDB is a distributed, fault-tolerant graph database built to store adjacency lists (directed edges) with high throughput and low latency. It was developed by Twitter to manage social graphs (e.g. followers, blocks), secondary indices, and relationships that require fast read/write but without needing full graph-traversal (multi-hop) queries. It supports operations like archiving edges, paginating very large result sets, sorting by position, replication, and horizontal scaling. The project is archived and no longer under active maintenance.
Features
- Supports massive adjacency lists for directed graphs (source → destination and destination → source stored)
- Supports add / update / remove of edges at high rate (writes) and paging through large result sets (reads)
- Ability to mark edges as “archived” (cold storage) and restore them later
- Sort position on edges to allow ordering (for example by timestamp)
- Horizontal scaling and replication for fault tolerance and performance
- Designed to be simpler than full graph databases: no multi-hop / graph walking, minimal feature scope, optimized for adjacency queries
Programming Language
Scala
