Starting with our very first use case, we walk through how the initial implementation took shape, the challenges we encountered, and the successes that validated our approach. We highlight the lessons learned along the way that shaped how we design and operate event‑driven solutions today. **Speaker Two:** Olena Kutsenko, Staff Developer Advocate, Confluent **Title of Talk:** The art of structuring real-time data streams into actionable insights **Abstract:** Real-time data can be messy, unpredictable, and hard to manage. To unlock its full potential, you need a way to turn raw streams into clean, structured data. In this talk, we’ll show you how to use Apache Kafka, Apache Flink, and Apache Iceberg to organize real-time data streams efficiently and prepare them for advanced use cases, including AI applications. We’ll start by explaining how Kafka handles high-speed data streams and how Flink processes these streams in real time. You’ll learn how to use Flink to transform raw data into structured formats, ensuring it’s ready for storage and analysis. Then, we’ll dive into Iceberg, demonstrating how it stores and organizes structured data for easy querying and visualizing. Through clear examples, we’ll walk you through building a practical pipeline that turns chaotic data streams into organized structure. By the end of the session, you’ll know how to manage real-time data effectively and set the stage for downstream AI and analytics. Whether you’re a beginner or an experienced developer, this talk will give you the tools to simplify and enhance your data pipelines! **Bio:** Olena is a Staff Developer Advocate at Confluent and a recognized expert in data streaming and analytics. With two decades of experience in software engineering, she has built mission-critical applications, led high-performing teams, and driven large-scale technology adoption at industry leaders like Nokia, HERE Technologies, AWS, and Aiven. A passionate advocate for real-time data processing and AI-driven applications, Olena empowers developers and organizations to use the power of streaming data. She is an AWS Community Builder, a dedicated mentor, and a volunteer instructor at a nonprofit tech school, helping to shape the next generation of engineers. As an international speaker and thought leader, Olena regularly presents at top global conferences, sharing deep technical insights and hands-on expertise. Whether through her talks, workshops, or content, she is committed to making complex technologies accessible and inspiring innovation in the developer community. \*\*\* If you are interested in speaking at or hosting a meetup, please contact community@confluent.io

Join the waitlist now and secure your spot: [https://buff.ly/rsTZGaq](https://buff.ly/rsTZGaq) 📅 April 16th 📍 TT Vasumweg 44, Amsterdam ⏰ 8:30 AM - 4:30 PM We look forward to seeing you !

Come discuss books and make new friends 🌈✨ How the meeting works: While we are waiting for everyone to arrive, we have tea and get comfortable. Once most of the group is seated (please aim to arrive on time to help with this!) we go around introducing ourselves. From there we have a loosely structured discussion that can go in whatever direction feels natural. Once we've talked about everything we want to related to the book we often hang out for a while later to chat about other things for anyone who wants to stay. April's book will be Confessions of a Mask by Yukio Mishima. The Dutch translation (Bekentenissen van een gemaskerde) is available at de bibliotheek. The English translation unfortunately has to be procured elsewhere. Confessions of a Mask tells the story of Kochan, an adolescent boy tormented by his burgeoning attraction to men: he wants to be “normal.” Kochan is meek-bodied, and unable to participate in the more athletic activities of his classmates. He begins to notice his growing attraction to some of the boys in his class, particularly the pubescent body of his friend Omi. To hide his homosexuality, he courts a woman, Sonoko, but this exacerbates his feelings for men. As news of the War reaches Tokyo, Kochan considers the fate of Japan and his place within its deeply rooted propriety. Confessions of a Mask reflects Mishima’s own coming of age in post-war Japan. Its publication in English―praised by Gore Vidal, James Baldwin, and Christopher Isherwood―propelled the young Yukio Mishima to international fame. The meeting will take place at De Uithoek handarbeidlokaal, an 8 minute cycle / 20 minute walk away from Utrecht Centraal. Everyone is welcome who has read the book (or DNF, and is okay with spoilers) by the time of the meetup. The book club is hosted in English. Please update your RSVP if you find out you cannot attend. Hope to see you there! 🏳️‍🌈📚

Natalia Ginzburg wrote her masterful, Strega Prize winning novel *Family Lexicon* while living in London in the 1960s. Homesick for her big, noisy Italian family, she summoned them in this novel, which is a celebration of the routines and rituals, in-jokes and insults and, above all, the repeated sayings that make up every family. The father, Giuseppe Levi, is a Jewish scientist, consumed by his work and a mania for hiking. Impatient and intractable, he is constantly at odds with his impressionable and wistful wife Lidia - yet he cannot be without her. Together they preside over their five children in a house filled with argument and activity, books and politics, visitors, friends and famous faces. But as their children grow up against the backdrop of Mussolini's Italy, the Levi household must become not only a home - but a stronghold against fascism. Intimate, enchanting and comedic, Family Lexicon is an unforgettable novel about memory, language, and the lasting power that family holds over all of us.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services) Sign up also accessible via [Transform Labs Luma](https://luma.com/55umjqta)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
