JUST MAKE IT SCALE: AN AURORA DSQL STORY

Amazon Aurora DSQL is a serverless, distributed relational database service optimized for transactional workloads.

DSQL was written in Rust, which gave the team the control they needed to avoid tail latency in the core parts of the system, the flexibility to integrate with a C code base like Postgres, and the high-level productivity the team needed to stand up its control plane.
