Cornus: Atomic Commit for a Cloud DBMS with Storage Disaggregation
Summary: Cornus redesigns 2PC for storage-disaggregated cloud DBMSs, exploiting an atomic compare-and-swap primitive in shared storage to eliminate coordinator-driven eager log writes and shorten the commit critical path. Enables non-blocking progress on coordinator failure and shows up to 1.9× commit-latency reduction on Azure Blob and Redis. (summarized by gpt-5-mini on Feb 09 2026)
