Fluree - Cloud-Native Ledger Graph Database
summary
Fluree is a cloud-native, open‑source ledger graph (semantic triple) database that pairs a separate ledger backplane and query servers so writes go to a Raft-backed ledger and reads run from in‑memory query nodes. It implements bi‑temporal time travel (queries for past moments cost about the same as current), a sandboxed smart‑function VM, three main indexes (SPO/POS/OPS), and immutable 100KB leaf files (~3,000 triples each) that let one‑level = 50MB, two = 25GB, three = 12.5TB, four ≈6PB. Query servers can run in browsers, on JVMs, or in cloud object storage, and the system is deployed and working.
