Fauna has successfully completed the Jepsen tests for version 2.5.4 and 2.6.0, demonstrating its reliability, correctness, and scalability in a cloud-native setting. The tests, led by Kyle Kingsbury of Jepsen.io, covered various fault conditions and administrative actions to simulate public cloud unreliability, validating Fauna's architecture and implementation. Fauna's design is based on peer-reviewed research into transactional systems, combining Calvin's cross-shard transactional protocol with Raft's consensus system for individual shards. The testing revealed that Fauna meets its expected isolation levels, avoids anomalies present in other databases, and maintains ACID semantics at all times. Fauna's architecture is sound, self-operating, and offers the highest possible level of correctness, making it a reliable choice for enterprise workloads in the cloud.
