Online Schema Evolution is (Almost) Free for Snapshot Databases
Summary: Tesseract models schema evolution in MVCC snapshot databases as data-definition-as-modification (DDaM), turning DDL into table-wide data modifications handled by the existing concurrency control. With minor tweaks to snapshot isolation, it enables online transactional schema changes with no downtime and negligible performance impact. (summarized by gpt-5-mini on Feb 09 2026)
