Living in Parallel Realities – Co-Existing Schema Versions with a Bidirectional Database Evolution Language
Summary: Introduces InVerDa, co-existing schema versions via BiDEL, a bidirectional evolution language that auto-generates delta code. Data changes propagate across versions; evolving the physical design is decoupled, with each version acting as a full DB. (summarized by gpt-5-nano on Feb 09 2026)
