Using Vitess in our CI/CD pipeline
Here at Vinted, we adhere to the continuous deployment principle, meaning that each merge to the main branch of the code repository initiates an automatic deployment process. As a result, the merged code goes live in a short period of time. Merge small and merge often are two practices that are instrumental to our day-to-day engineering work.
This approach mitigates friction when working on a shared code base, shortens the feedback loop, and reduces the anxiety of breaking the production environment with a gigantic change. But for it to actually work, one must have very good code test coverage, deployment automation tools with solid safeguards in place, a reliable observability stack to catch problems in the deployed products, battle-tested rollback, recovery procedures, and much more.
In this post I’ll touch on the testing phase. Specifically, I’m going to explain how we make use of the Vitess database to run backend tests of our core application.Continue reading →
