A Tree-Structured Two-Phase Commit Framework for OceanBase: Optimizing Scalability and Consistency

Summary: Recasts OceanBase 2PC as a tree over coalesced log-stream participants, cutting coordination by up to 99% for 100 partitions. Migration leaves and uncertainty states preserve linearizability and safe retries during topology changes. (summarized by gpt-5.6-luna on Aug 28 2026)
