Breaking the Isolation-Freshness Trade-off: Joint Adaptive Storage Optimization for HTAP Systems
Summary: Jasper breaks the HTAP isolation-freshness trade-off via joint adaptive storage optimization: workload-aware horizontal/vertical partitioning plus selective column-store materialization for update-sparse, query-heavy partitions. Fine-grained, dynamic layouts in TiDB cut sync overhead and improve both isolation and freshness vs static dual/single-store designs. (summarized by gpt-5.4-mini on Apr 12 2026)
