Jepsen's analysis of MariaDB Galera Cluster 12.1.2 reveals significant safety violations: it loses committed transactions during node crashes and network partitions, fails to meet its claimed isolation level, and exhibits stale reads. The findings contradict MariaDB's 'no lost transactions' guarantee, highlighting critical reliability issues in a widely used database system.
Background
MariaDB Galera Cluster is a replicated, multi-master SQL database system designed for high availability. Jepsen is a well-known framework for testing the safety and consistency of distributed systems, often uncovering flaws in databases' claimed guarantees.
