Eindhoven Data Community

Microsoft Fabric: From platform reality to capacity mechanics
New to Microsoft Fabric, or using it daily without knowing what happens under the hood? This meetup is your primer. Fabric is Microsoft's all-in-one data platform. It combines data engineering, warehousing, data science, real-time analytics and Power BI on one shared storage layer, OneLake, all running on a capacity you pay for. We'll start with an honest look at how the platform is built and where it shines or struggles in production. Then we'll open up the black box of capacities, so you understand how your workloads consume resources and why things sometimes slow down. No prior knowledge is needed. Just bring your curiosity, and stay for food and drinks in Eindhoven.

Taras Lozovskyi - Microsoft Fabric: The Reality Behind the Momentum
This foundational session breaks down Microsoft Fabric from an architectural and engineering perspective. We’ll look at the platform's real pros and cons, covering the core building blocks: OneLake, open Delta storage, zero-copy patterns, and compute workloads—from Spark and Materialized Lake Views (MLVs) to the line between raw ingestion and end-to-end orchestration.

Along the way, we’ll highlight where Fabric genuinely simplifies daily work, where the operational trade-offs lie, and what rough edges to watch out for in production.
Whether you work in data engineering, platform architecture, analytics, or AI, this talk gives you a pragmatic map of the ecosystem—setting the technical stage right before our Microsoft speaker dives into how capacity sizing and compute work under the hood.

Daan Humblé - Fabric Capacities: A Primer
Everyone working in Fabric runs on a capacity. Yet for most people it still feels like a black box. What are those CUs actually measuring? What does "bursting" mean? And why does your capacity suddenly say no when nobody seems to be doing anything?

In this session we'll open the box together. We start with the number that really matters. It isn't CUs: it's the percentage of your capacity you're using. From there we'll walk through how your organization's usage is charged against your capacity, and what bursting, smoothing and throttling mean for your day-to-day. We'll finish with a short tour of the Capacity Metrics App: where to look first, and which signals you can safely ignore.

No prior knowledge required. This isn't just for (aspiring) capacity admins: if you build, run or query anything in Fabric, your work lands on a capacity, and knowing how it behaves will help you build better solutions.

About Daan Humblé | Cloud Solution Architect at Microsoft
I help organizations and individuals make better Data & AI decisions.

As a Cloud Solution Architect at Microsoft, I work with enterprises on data platform architecture, governance, Microsoft Fabric, and AI transformation. My focus is not just on technology, but on helping teams understand trade-offs, avoid common anti-patterns, and make decisions that lead to sustainable outcomes.

My sessions cover both the technical and strategic sides of Data & AI, from data modeling and performance optimization to governance, architecture, and AI readiness. I enjoy explaining the "why" behind the "how" and sharing practical lessons that attendees can apply immediately.
