Using Erlang, Riak and the ORSWOT CRDT at bet365 (...)
summary
bet365 reimplements a mission‑critical middle layer using Erlang and Riak 1.4 with an integrated ORSWOT CRDT (dotted version vectors) so clients never handle siblings; unique actor names trade off concurrency against version‑vector size. production load testing uses battlebench and replay logs, catches 100,000 changes/sec and 2.5M concurrent push users, and exposes network/disk hotspots. phased rollout, custom monitoring and reconciliation tooling prove the system scales to many times peak, survives data‑center failures with minimal human intervention.
