Apache Superset has always been leading the charge on open-source BI, but now it’s getting ready to truly take over the BI world. Learn all about Superset’s new extensions architecture that will allow users and developers to more rapidly expand and improve the product’s capabilities, while simplifying life for both developers and maintainers.

After years of pushing ClickHouse to its outer limits in real-world observability workloads, we’ve learned a lot - sometimes the hard way - about getting the most out of your analytics system. But before you dive into inverted indexes, object storage, and terabyte-scale performance tuning, it’s critical to get the basics right. This talk starts at the beginning, walking through the fundamentals that make ClickHouse such a powerful engine for analytical workloads, the performance advantages of columnar storage, how its architecture supports horizontal scaling, and why it’s ideal for high-throughput, low-latency queries.

Commercial Open Source Software (COSS) is a burgeoning business sector. This talk will focus on how the demand for COSS will be driven by the advance of LLM and AI.

How we built an open source observability stack that can track every frame of our game. https://github.com/madesroches/micromegas/ When every frame lasting 1/60th of a second can record thousands of events, traditional time series databases just won’t do.

The retail sector’s shift toward omnichannel fulfillment and instant availability demands has exposed critical limitations in traditional batch-processed inventory systems. This presentation demonstrates how open source Event-Driven Architecture (EDA) tools are transforming retail inventory analytics, enabling continuous real-time processing that delivers superior accuracy, automated insights, and scalable supply chain responsiveness. Open source analytics platforms are proving their value in retail operations, with adopters experiencing up to 30% fewer stockouts and 15% improved inventory accuracy compared to proprietary batch systems.

As AI transforms how we build, scale, and interact with software, one thing is becoming clear: open source isn’t just keeping up—it’s leading. In this keynote, Max Beauchemin, creator of Apache Superset and Apache Airflow, unpacks why open source is uniquely positioned to dominate in the age of AI. From training data to developer velocity, open projects have structural advantages that proprietary vendors simply can’t replicate. We’ll explore how LLMs ““know”” open source deeply, how AI-native workflows amplify OSS contributions, and why communities—not corporations—are becoming the new centers of gravity for software innovation.

Apache Iceberg™ made great advancements going from Table Format V1 to Table Format V2, introducing features like position deletes, advanced metrics, and cleaner metadata abstractions. But with Table Format V3 on the horizon, Iceberg users have even more to look forward to. In this session, we’ll explore some of the exciting new user-facing features that V3 Iceberg is about to introduce and see how they’ll make working with Open Data Formats easier than ever!
