Jepsen: TigerBeetle 0.16.11
ackground TigerBeetle is an Online Transactional Processing (OLTP) database built for double-entry accounting with a strong emphasis on safety and speed. It builds on the Viewstamped Replication (VR) consensus protocol to offer Strong Serializable consistency.
These parameters were carefully tuned across a variety of concurrencies, request rates, hardware environments, and fault conditions to find a reasonable balance of successes and failures, non-empty query results, attempted invariant violations, and so on. The architecture appears sound: Viewstamped Replication is a well-established consensus protocol, and TigerBeetle’s integration of flexible quorums and protocol-aware recovery seem to have allowed improved availability and extreme resilience to data file corruption. This work would not have been possible without the invaluable assistance of the TigerBeetle team, including Fabio Arnold, Rafael Batiati, Chaitanya Bhandari, Lewis Daly, Joran Dirk Greef, djg, Alex Kladov, Federico Lorenzi, and Tobias Ziegler.
