Unraveling Multi-Master Replication in PostgreSQL: Architectures and Solutions

Abstract: PostgreSQL, one of the world’s most advanced open-source relational database management systems, has undergone significant evolution over the years, with its vast ecosystem continuously expanding to meet the diverse needs of the modern digital age. One area that has captured significant attention is database replication, specifically multi-master replication (MMR). In this presentation, we delve deep into the intricacies of multi-master replication in PostgreSQL, shedding light on both the underlying architecture and the various existing solutions that have been developed to facilitate this complex task.

Key Takeaways:

Understanding MMR: Gain a comprehensive understanding of what multi-master replication is, the challenges associated with it, and the scenarios where it is most beneficial.

Architectural Overview: Discover the architectural principles behind MMR in PostgreSQL, and how these guide the creation and operation of highly available, distributed systems.

Existing Solutions in the Spotlight: Examine the current state-of-the-art solutions available within the PostgreSQL ecosystem, such as pgEdge(spock), BDR (Bi-Directional Replication), and Postgres-XL. We will evaluate their strengths, limitations, and best-use cases.

Performance and Conflict Management: Unpack the issues related to conflict resolution in MMR environments, alongside strategies to ensure optimal performance without compromising data integrity.

Future Prospects: Get a glimpse of the evolving landscape of multi-master replication in PostgreSQL, exploring upcoming features, community contributions, and what the future might hold for distributed database systems.
