Opportunities for Optimism in Contended Main-Memory Multicore Transactions
Summary: Revisits OCC under contention, showing its apparent collapse often stems from non-CC implementation choices. Commit-time updates and timestamp splitting substantially boost both OCC and MVCC, yielding 3.6× and 3.4× TPC-C gains. (summarized by gpt-5.6-luna on Jul 24 2026)
