Optimistic Concurrency Control by Melding Trees
Summary: Meld: an optimistic concurrency control for tree-structured data; transactions log updates and are evaluated against a cached partial-copy of the last committed state in log order. On commit, updates merge into that state; enables Hyder to scale without partitioning, delivering up to 400k updates/s for 2-op txs and 130k for 8-op txs. (summarized by gpt-5-nano on Feb 09 2026)
