FoundationDB and Node.js: Year in Production
Talkat FoundationDB Summit 2019 · on Monday, 2019-11-18· at 13:50· Grand Ballroom 5, Marriott Marquis San Diego Marina·
summary
Company moves entire backend to FoundationDB and builds a Node.js library fdb.openland that provides distributed locks, work queues, an entity/record-like layer, distributed random IDs and singleton workers. Deployment runs ~200 GB across ~5 coordinators + ~5 storage nodes plus backup and lock machines with ~30 client processes; the cluster shows 40k ops/sec in parallel tests versus ~10 req/s per process on prior SQL stacks. Typical read path shows a version read ~10 ms and a profile+batch fetch ~16 ms, so fetching 20 users can hit ~0.33 s. Results: stateless app servers, near-zero maintenance, small team shipping safely and only 30 seconds of downtime during an upgrade.
