SunStorm: Geographically distributed transactions over Aurora-style systems
Summary: SunStorm extends Aurora-style shared-storage (separate compute and storage) to support multiple geographically distributed writer nodes that manage partitioned data, eliminating the single-writer scalability bottleneck. Retains Aurora efficiency (avoids full distributed commit/coordination) while improving global write latency by over an order of magnitude via local writers and geographic partitioning.
