Join us on March 17th from **6:00pm** for a Data Streaming meetup hosted by **Snowflake** and supported by **Dremio** and **Streambased!** 📍**Venue:** **Snowflake** One Crown Place, London EC2A 4EF, U.K. 5th & 6th floors · London **PLEASE bring your PHOTO ID and REGISTER with your details for security purposes.** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:00pm: Celeste Horgan, Developer Advocate, Snowflake * 7:00pm - 7:30pm: Tom Scott, Founder & CEO, Streambased * 7:30pm - 8:00pm: Will Martin, EMEA Evangelist, Dremio * 8:00pm: Q&A Networking 💡**Speaker One:** Celeste Horgan, Developer Advocate, Snowflake **Title of Talk:** I have no idea what I’m doing, or: building an Apache Spark to Apache Iceberg pipeline from scratch for data ingestion **Abstract:** Transitioning to Apache Iceberg requires a shift in how we think about data storage and ingestion. Enter: Apache Spark… maybe? Exactly how is an open question. In this talk we’ll go through the trial-and-error process of ingesting data into an Apache Iceberg table using Apache Spark. We’ll learn about file formats for Apache Iceberg tables, when to partition (and what the consequences are), common integration mistakes (as made by me in the learning process), and what Apache Spark does best, and when a different tool might work better. Most importantly, we’ll learn how to learn a new piece of software fast using AI to help rather than hinder. **Bio:** Celeste Horgan is a Sr. OSS Advocate at Snowflake. She got her start in open source at the Linux Foundation, where she supported the Kubernetes project on their documentation. From there, she went on to work at Aiven on open source data platforms, and now continues that work evangelizing data systems for Snowflake. Her work on inclusive language has been featured in the New York Times, and she lives in London. 💡**Speaker Two:** Tom Scott, Founder & CEO, Streambased **Title of Talk:** Turning The Database Inside Out **Abstract:** Over a decade ago, Martin Kleppmann's Turning the Database Inside Out reshaped how we think about data systems, putting the event stream at the heart of storage and computation. That vision inspired a generation of systems built atop Kafka, Flink, and event-driven materializations. But what if we never finished what Martin started? This talk takes the next leap, reimagining not just the transaction log, but the entire database through the lens of streaming. We'll keep Kafka as our canonical source of truth, but enrich it with the missing primitives: long-term storage, indexes, and projections. To achieve this, we'll move beyond Kafka's simple produce/consume model and embrace Apache Iceberg as the new foundation for durable, queryable event data. **Bio:** Long time enthusiast of Kafka and all things data integration, Tom has more than 15yrs 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. 💡**Speaker Three:** Will Martin, EMEA Evangelist, Dremio **Title of Talk:** From Stream to Table: Building Kafka-to-Iceberg Pipelines **Abstract:** While Kafka excels at streaming data, the real challenge lies in making that data analytically useful without sacrificing consistency or performance. This talk explores why Apache Iceberg has emerged as the ideal streaming destination, offering ACID transactions, schema evolution, and time travel capabilities that traditional data lakes can't match. Learn about some foundational tools that enable streaming pipelines and why they all converge on this industry standard table format. **Bio:** Will Martin is the EMEA Evangelist at Dremio. Beginning with a background of statistical analysis in particle physics, his professional journey has spanned multiple industries, including banking, shipping logistics, entertainment, healthcare, defence, and customer 360. With experience as a data engineer, solutions architect, and software developer, he has spent 15+ years collaborating with companies and organisations across EMEA and APAC, including roles at CERN, Deloitte, and Tamr. \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

If you've not been to one of our events before then here is what you can expect. CRAP (Conversion Rate Optimisation, Analytics, Product) Talks is a cross-discipline event. We don't work in silos so why network and learn in silos. In the past we've had speakers from Data, Analytics, CRO, Product, Marketing, Data Science, Design and Research and so many more. If you work in tech, chances are you work cross-functionally, so come along and meet people doing amazing things in tech. **Hosts:** Meta **Venue:** Meta Brock, 10 Brock St, London NW1 3FG **Date:** 17/03/2026 6pm doors open Talks kick off at 630 Wrap up approximately 9:00pm. **Speakers:** * **Speaker Name:** [Tom Collingburn](https://www.linkedin.com/in/tom-collingburn-7b7b5a16a/) \| [Tom Milne](https://www.linkedin.com/in/thomas-milne-3422482b/) * **Title:** Senior Data Analyst \| Head of Experience Insights * **Talk Name:** The Measurement Dilemma: ITV's Long Term Holdout Group * **Talk Summary:** ITVX reaches more than 15 million viewers each month across web, mobile and 16 different TV applications. Our Product & Tech teams are rapidly expanding and updating the viewer experience to meet the challenges of an extremely competitive entertainment marketplace. But how do we know the cumulative impact of these Product changes is positive, in a content-driven business that is hugely influenced by competition and seasonality? In this talk we’ll show how we adopted a Long Term Holdout Group to answer this critical business question. We’ll share the technical successes, the inevitable hurdles, and the hard-won learnings we gathered along the way. * **Speaker Name:** [Igor (Iggy) Skokan](https://www.linkedin.com/in/igorskokan/) * **Title:** Director, Marketing Science, Meta * **Talk Title:** Measure What Matters with Incrementality * **Talk Summary:** Shifting consumer behaviors and the rise of formats with limited click opportunities like video have made the attribution models most advertisers rely on less effective. To capture a fuller picture of performance, advertisers must build a trusted suite of tools and methods to get closer to measuring incrementality, i.e., the true, additive value of their campaigns. This session covers how to build a practical measurement stack to estimate incrementality - the true impact of campaigns.. **Fireside Chat hosted by Parveen Downer:** * **Guest in the hot seat:** [Manasi Goel](https://www.linkedin.com/in/manasi-goel-9aba52a1/) * **Title:** Head of People & Culture at EE * **Talk Title:** Stop the Slop: Building a Real AI Builder Culture * **Talk Summary:** Most organisations are currently caught in the "AI Slop" trap: generating pages of meaningless text , chasing "10x productivity" myths , and seeing zero actual return on investment. But for product teams in mature, complex organisations (or most organisations for that matter), the real opportunity isn't about doing more work—it’s about doing better work. Join us for a candid, hype-free conversation on what it actually takes to integrate AI into the heart of a "legacy" organisation. We’re moving past the scaremongering and the "human-in-the-loop" clichés to explore how teams can "slow down to speed up". Forget the tech-bro manifestos. This is a session for those who want to build a career that is inspired, hopeful, and—most importantly—slop-free.

🤖 **Most AI writing tools keep you in a chat box. This talk is about what happens when you step outside it.** Led by **[Max Clayton Clowes](https://www.linkedin.com/in/maxclaytonclowes/)**, afractional product manager, we'll look at how technical writers — regardless of coding background — can use Claude Code to work in a docs-as-code environment, extend their documentation tooling, and build workflows that hold their own standards over time. We'll cover: \- Why Claude without proper context is a frustrating experience and how Skills fix that \- How Claude Code enables technical writers to work with frameworks like Docusaurus without needing to be developers \- Building and extending documentation tooling — plugins\, components\, GitHub Actions — that most teams don't have the time or skills to build from scratch \- Using Claude Code to maintain docs at scale: auditing\, keeping content in sync with a changing codebase\, and automating the checks that keep quality consistent The talk is aimed at technical writers of all levels. You don't need to be comfortable in a terminal to get value from it — we'll show a clear path from the Claude web interface through to Claude Code, and you can engage at whichever level suits you. **Want to follow along?** Pick the level that works for you and get set up before you arrive: \- Web interface: A Claude account at claude\.ai\. Free tier is fine\. \- Claude Code: Download the Claude desktop app at claude\.com/download\. Requires a paid Claude plan \(Pro or above\)\. On macOS/Linux\, run *curl \-fsSL https://claude\.ai/install\.sh \| bash* to install. Windows users can download the installer directly. No other dependencies needed. Not set up? Everything will be on screen — you can explore at your own pace afterwards. **🗒️ Agenda** **When:** Thursday 19 March, from 6.30pm **Where:** The Gallery @ [The Corner](https://maps.app.goo.gl/C1iSyEeMffB7BZjf6) (42 Adler Street, E1 1EE) **What:** **18.30 - 19.00** Arrival **19.00 - 19.10** Welcome & Housekeeping **19.10 - 19.40** Part 1 of presentation **19.40 - 20.00** Break **20.00 - 20.30** Part 2 of presentation **20.30 - 21.00** Closing and networking *All times are approximate.* **📍 How to find us:** Enter the hotel, turn right and right again past the bar to find The Gallery meeting room.

**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 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA

We’re still working to get more people into these Meetups, but our goal is to give PlayYourCourt members a few social tennis outings each week in addition to your practice sessions and Challenge League matches. These Meetups are co-ed, super laid back, and all skill levels are welcome. Post your skill level and a suggested court in the comments section so we can round up as many players as we can for some tennis fun! Also, if you’re looking to meet new practice partners or play some matches and you aren’t already in the PlayYourCourt Community, you can go here to see what we’re all about and sign up: https://www.playyourcourt.com/tennis-community/columbus-oh/meetup/ If you love tennis, we’d love to have you! Be sure and watch the quick video that explains how everything works. Happy hitting! - Scott
