FOSS 2025: From Source Code to Source of Truth: 30 Years of Open Source Database Evolution
October 2 – October 3 Chernihiv Polytechnic National University, Chernihiv Oblast, Ukraine
Alkin Tezuysal speaks at FOSS 2025. The goal is to bring academia, industry, and open communities together around the practical use of Free and Open Source Software (FOSS) in education, research, and business. The event is hosted by Chernihiv Polytechnic National University.
This talk traces the evolution of open source databases over the past three decades—from the early rise of MySQL and PostgreSQL to the NoSQL wave and today’s real-time, AI-driven architectures. We’ll explore the shifting landscape of transactional vs. analytical systems and spotlight ClickHouse as a game-changing columnar engine redefining performance at scale. Learn how community-driven innovation, cloud disruption, and new workloads are shaping the future of open data infrastructure.
