Databases are some of the most important contributing factors determining system reliability, scalability and maintainability. Most of CircleCI’s core services are data-intensive, storing millions of rows per week, and growing linearly with usage of our CI/CD platform. As a result they contributed to numerous reliability issues - from degraded RDS performance, long database migrations, and painful database upgrades.

In this presentation, the speaker will discuss how we reduced CircleCI’s operational risk by curbing our database growth by a third.
