- HorizonDB: Co‑Designing PostgreSQL and Azure for Cloud‑Native OLTP
- System:
- HorizonDB
Talk Info:
Azure HorizonDB is a new PostgreSQL service that improves the OLTP performance and reliability of upstream PostgreSQL through co‑design. By evolving both Azure’s infrastructure and PostgreSQL itself, HorizonDB enables the two to work together more efficiently. This talk introduces the architecture of HorizonDB and explores several key design and implementation decisions that enable more scalable, reliable PostgreSQL in Azure.
This talk is part of the PostgreSQL vs. The World Seminar Series.
