Session Description

Database availability is calculated in terms of Uptime as currency and vendor lock-in is a risk, Open-source databases are powering a quiet revolution. At the heart of it lies PostgreSQL, and it's not just standing its ground, it's going multi-master.

This session dives into how distributed PostgreSQL, with true multi-master capabilities, is being deployed across industries to solve high availability, global distribution, and regulatory challenges. all while staying free and open.

We’ll explore the technical underpinnings of multi-master PostgreSQL, why organizations are choosing FOSS over proprietary options, and what happens when Open-source meets mission-critical scale. Expect real use cases, architectural patterns, and lessons learned from deployments in edge environments.

If you're passionate about PostgreSQL, distributed systems, or building future-ready infrastructure, this talk is for you.

Key Takeaways

  • Getting started: Practical tips and tools to explore multi-master PostgreSQL in your own stack.

  • Why FOSS matters: The strategic advantages of open-source database infrastructure in distributed environments.

  • When to go multi-master: Use cases across Fintech, SaaS, and global-scale applications.

  • Architectural patterns: Common design choices for conflict resolution, write scaling, and region-based sharding.

  • Deployment lessons: Real-world challenges in consistency, failover, and operational overhead — and how teams solved them.
