Aurora DSQL: Scalable, Multi-Region OLTP

Aurora DSQL: Scalable, Multi-Region OLTP A paper! Our new paper, Aurora DSQL: Scalable, Multi-Region OLTP, is now available on Arxiv. I’m excited about this one: it’s a fully end-to-end look at how Aurora DSQL works, from query processing, to transactions, to replication, to the control plane. We’ve shared most of this content before in other forms, on this blog, on Marc Bowes’ Blog, Werner’s Blog, in talks, and on the AWS blog. But this version covers all the ground, all in one place. You should read it. Or check out the interactive transaction simulator to get a feel for how it works. Some highlights Our overall goal was to build a relational database system that simplifies the work of application building and operations, freeing builders from worrying about scale, reliability, durability, and even multi-region fault tolerance. A database of first resort, which is simple and easy to adopt at low scale, and grows with the application, without adding complexity. I’ve written about…
