DSQL Vignette: Reads and Compute
In today’s post, I’m going to look at half of what’s under the covers of Aurora DSQL, our new scalable, active-active, SQL database. If you’d like to learn more about the product first, check out the official documentation, which is always a great place to go for the latest information on Aurora DSQL, and how to fit it into your architecture.
We use a novel service-oriented architecture (see Figure 1) with a multi-tenant scale-out storage service that abstracts a virtualized segmented redo log and is loosely coupled to a fleet of database instances. Since launching Lambda, we’ve learned a lot about how to do fast, efficient, and dynamic compute scalability, and built some really cool technology to make it happen, like the Firecracker VMM 3. We add MicroVMs in the AZs and regions your connections are coming from, keeping your SQL query processor engine as close to your client as possible to optimize for latency 6.
