Aurora DSQL: Scalable, Multi-Region OLTP

Quality: 8/10 Relevance: 9/10

Summary

Aurora DSQL presents a serverless, multi-region OLTP database built on a disaggregated architecture, separating compute, storage, and coordination to scale across regions. It uses PostgreSQL-compatible SQL, MVCC with precision timestamps, and distributed adjudicators for commit-time coordination, enabling low-latency reads and ACID transactions with strong availability. The paper positions DSQL as a cloud-scale solution that supports elastic scaling and regional resilience.
