Multiversion Concurrency Control for Multiversion B-Trees
arXiv:2606.09133v1 Announce Type: new Abstract: Multiversion concurrency control (MVCC) enables scans to read data from a committed snapshot (version), reducing conflicts with write operations compared to traditional concurrency approaches. Currently, versioned records are often managed in a B$^+$-tree using version chains. However, version chains introduce overhead during scans and can still lead to conflicts between scans and writers.
