Diva: Making MVCC Systems HTAP-Friendly
Summary: Introduces Diva (Decoupling Index from Version Data) to physically separate MVCC index from version data for HTAP-friendly design. Uses provisional indexing and time-interval garbage collection to decouple concerns, breaking the space-time tradeoff; demonstrated on PostgreSQL and MySQL under HTAP workloads.
