From Source Code to Source of Truth_ 30 Years of Open Source Database Evolution
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.
