May Edition ✨✨! We will be at Kraken Tech (Octopus Energy Group), London office! (in-person only event, no streaming) **Talks:** **Django's GeneratedField by example — Paolo Melchiorre** Learn how to use Django 5.0's GeneratedField through practical examples. This field lets the database compute values automatically based on other fields in your model — a powerful feature that's easy to underuse. Paolo will walk through real-world use cases to show where it fits and how to make the most of it. Paolo Melchiorre is a Python backend developer, Django contributor, and Python Software Foundation Fellow. He serves on the Django Software Foundation board, co-organises PyCon Italia, and is a coach for Django Girls and a navigator for the Djangonaut Space mentorship programme. *** **Django in the Lab: how web development is reshaping behavioural research — Andy Woods** Off-the-shelf platforms can't always keep up with the complexity of academic research. Andy has been using Django since version 1.11 to build tools that can — from coordinating live location-based VR studies to running inclusive diary studies via WhatsApp and auditing immersive experiences for accessibility. He'll share where Django works especially well in academic settings, what surprised him along the way, and why this moment feels like a real opportunity for the Django community. Andy Woods is a Senior Research Engineer-Psychologist at CoSTAR & StoryFutures, Royal Holloway, University of London, and a Django Software Foundation Individual Member. **Want to share your Django or Python knowledge?** We’d love to feature your talk!

Join us on May 7th from **6:00pm** for a Data Streaming meetup hosted by **[Fresha](https://www.fresha.com/)**! 📍**Venue:** **Fresha** The Tower, 207 Old Street London, EC1V 9NR 7th Floor **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name, Email. Thanks!** **DOORS CLOSE AT 7PM FOR SECURITY.** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:00pm: Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha * 7:00pm - 7:30pm: Olena Kutsenko, Staff Developer Advocate, Confluent * 7:30pm - 8:00pm: Tom Scott, Founder & CEO, Streambased * 8:00pm - 9:00pm: Q&A Networking 💡**Speaker One:** Anton Borisov, Principal Data Engineer, Fresha & Nicoleta Lazar, Sr. Data Engineer, Fresha **Title of Talk:** Apache Fluss: Streaming Storage for Real-Time Analytics **Abstract:** Apache Flink has largely solved streaming computation, but state management remains a bottleneck. Operator state—often backed by RocksDB—is scoped to individual jobs, making it hard to share state across pipelines without re-emitting it through systems like Apache Kafka. This leads to expensive joins and added operational complexity. Apache Fluss (incubating) addresses this by externalizing state into a streaming storage layer backed by S3. Its PrimaryKey tables act as upsertable key-value stores with replicated changelogs, enabling shared state tables accessible from Flink, Spark, or native clients. With Flink 2.1’s Delta Join, both sides of a join can perform lookups against Fluss-managed indexes—eliminating the need for large join state altogether. In this talk, we’ll introduce Fluss, show key use cases like CDC enrichment and bilateral joins, and share lessons from running it in production on EKS —including the trade-offs and rough edges we encountered. 💡**Speaker Two:** Olena Kutsenko, Staff Developer Advocate, Confluent **Title of Talk:** The journey of a record from Kafka topic to analytics table **Abstract:** Modern data platforms increasingly rely on streaming systems like Apache Kafka as the source of truth—but turning event streams into reliable, queryable analytics tables is far from trivial. This talk explores what really has to happen when moving data from a Kafka topic into an Apache Iceberg table. Beyond simple ingestion, we will walk through the essential steps: schema evolution, data normalization, partitioning, exactly-once guarantees, late-arriving events, and table maintenance. Using Confluent Tableflow as one concrete example, we will examine how these challenges can be addressed in practice. Along the way, we will compare alternative approaches—such as Kafka Connect sinks, stream processing pipelines, and custom ingestion frameworks—to highlight trade-offs in correctness, latency, and operational complexity. The goal is not to promote a single solution, but to provide a mental model for designing robust streaming-to-lakehouse pipelines, helping you understand what matters regardless of the tooling you choose. **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. 💡**Speaker Three:** Tom Scott, Founder & CEO, Streambased **Title of Talk:** *Infinite Kafka? Rethinking Retention with Iceberg* **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

Speaker: Richárd Kovács, CTO at Harikube Session Title: From Orchestration to Platform: The Missing Puzzles to Unify Polyglot Services on Kubernetes. Description: Imagine a world where Kubernetes itself becomes the unified platform—not just for container orchestration, but for serverless functions, microservices, and the entire API ecosystem. This presentation explores the missing architectural pieces required to make that world a reality. We focus on the architectural puzzles required to unify these layers: serverless functions, specialized Kubernetes Operators, and the powerful Aggregation API layer. By solving these integration puzzles, you can empower development teams to build real Cloud-Native nanoservices, microservices, and REST APIs on the same PaaS, in any language they choose, turning Kubernetes from a simple orchestrator into a powerful, opinionated application platform. **Agenda (GMT /UK ):** * 18:00: Welcome and refreshments * 18:30: Introduction - Ethan Sumner * 18:35: Richárd Kovács * 19:10: Break * 19:20: Frank Contrepois * 19:55: Close and Networking **Get Involved:** We are always keen to hear from: • Speakers — case studies, engineering deep dives, lessons learned, open-source talks • Hosts — organisations able to provide space for future meetups • Sponsors — support with refreshments, marketing, or accessibility If you would like to speak, sponsor, or host a future event, please get in touch with **[Ethan Sumner](https://www.linkedin.com/in/ethansumner404/)**[ ](https://www.linkedin.com/in/ethansumner404/)via LinkedIn.

Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
