What is Patroni, really?
Date: 2025-05-09
Time: 12:40–13:25
Room: Ballsaal 1
Level: Intermediate
Patroni is widely known as a high-availability solution for PostgreSQL, but what really makes it tick? In this talk, we’ll explore its architecture, core principles, and the hacks that keep it running smoothly. As a co-maintainer with 2.5 years in the trenches, I’ll share insights into its internals, unexpected challenges, and design decisions — both brilliant and painful. We’ll also discuss why, despite new developments in PostgreSQL high availability, Patroni remains a crucial tool—and where it might be headed next. Whether you're a user, contributor, or just curious about high-availability magic, this session will give you a fresh look at Patroni beyond the documentation, explain what Patroni really is and why it is still a thing.
