GitLab has an aggressive SLA, that made us research and develop solutions to improve our performance in all directions, on one of the most important components in our architecture, the PostgreSQL relational database. During this talk, we would like to invite you to explore the details about how we improve the performance of the main PostgreSQL relational database of GitLab.com in a high demanding environment with a load between 40k to 60k transactions per sec. We would share with you our projects, processes, and tools, and all tools being developed by our partner Postgres, including the main one, Database Lab.
