One DBMS, Two Modes, and a Bunch of Bugs: Catching Logic Bugs in Distributed DBMSs via Differential Testing
Summary: DistSQL differential-tests a DBMS in centralized vs distributed modes, using the former as a correctness oracle to expose distributed-only logic bugs. Key novelty: distribution-aware state mutation plus plan-feature-guided exploration, finding 65 unknown bugs across major systems. (summarized by gpt-5-mini on Apr 11 2026)
