**Fabric Data Warehouse with Tino Tereshko** For our June meetup, we’re excited to welcome Tino Tereshko, Partner Director of Product at Microsoft, responsible for Fabric Data Warehouse. Having previously spent several years at Google working on BigQuery, Tino later co-founded MotherDuck — the DuckDB-based SaaS analytics platform — before joining Microsoft to lead Fabric Data Warehouse. It’s fair to say Tino knows a thing or two about modern analytical databases. Tino is visiting from Seattle and has kindly offered his time to present at our London user group. The session will include an introduction to Fabric Data Warehouse, an overview of recent developments and future direction, followed by an open “Ask Me Anything” discussion where attendees can quiz Tino on all things data warehousing, Fabric, and analytics. **Agenda** 18:30 - Welcome, drinks, pizza & networking 19:00 - Main Session 20:30 - Close **Venue** Tenth Revolution offices in London. Aldgate House, 33 Aldgate High St, London EC3N 1DL Please provide your first and last name when registering for the event, as this is provided to building security to allow you entrance into the venue.

Black Stars in Dim Carcosa is the definitive Necronomicon field notes, the bridge between the book’s messy legend and the step-by-step reality of practice. It begins with the strange, contested history of the Simon Necronomicon and the postmodern blend of Mesopotamian magick and Lovecraftian literary myth it helped unleash, then poses a blunt question: what does the grimoire actually teach, and what changes when you put it into practice with discipline? At its core, this book offers a clear analysis of the Seven Gates and their operating logic, followed by step-by-step gatewalking practice, with practical attention to the Zonei, the Watcher and the Elder Signs, Marduk’s Fifty Names as operative keys, and the liminal cartography GANZIR and the Mauve Zone. From there, it opens a second, parallel approach to Mythos-inspired magick through a repeatable Lost Carcosa visionary praxis, circling Hastur and the King in Yellow with an emphasis on integration. Along the way, it treats dread as an epistemology and tangential tantrums as usable data, those sideways eruptions that can mark real contact, real risk, and real initiation

**We're back at Salisbury House for our summer London Airflow Meetup! Join fellow members of the data engineering community for an evening of engaging talks, great food and drinks, and exclusive swag!** **PRESENTATIONS** ***Talk #1: The Orchestration Layer: A Blueprint for Scaling Dynamic DAGs with Integrated Data Quality Gates*** * **Speaker**: [Vasudev Maduri](https://www.linkedin.com/in/vasudevmaduri/), Staff Data Engineer, Admiral Group Plc Ensuring high-quality data, accuracy, completeness, and schema validity is essential for building data trust. However, scaling data quality checks across diverse datasets often leads to duplicated boilerplate Python code, human error, and a massive bottleneck for Data Engineering teams. In this talk, we’ll explore how to shift data quality from a backlog of tech debt into an automated, self-serve developer experience directly tied to Airflow. We will demonstrate how to build a multi-faceted data observability framework that empowers end-user teams to define their own DQ rules without writing any Python code. By hiding complex Airflow code, users simply select their parameters—YAML configurations that instantly translate into fully dynamic, end-to-end DAGs, including in-flight data quality gates. The core of this session focuses on the technical implementation of integrated DQ checks that live directly *inside* the generated pipelines. You’ll learn how this metadata-driven approach enables a "shift-left" strategy for data observability, automatically enforcing data contracts and routing alerts without manual engineering intervention. ***Talk #2: Self-healing Data Pipelines in Airflow*** * **Speaker**: [Nilesh Khandalkar](https://www.linkedin.com/in/nileshskhandalkar/), Senior Manager, Capgemini Modern data pipelines remain largely reactive—failures trigger alerts, manual retries, and ongoing operational overhead for engineering teams. As systems scale, this approach introduces fragility, delays, and growing complexity in maintaining reliable workflows. This session explores how to design self-healing data pipelines in Airflow using practical patterns such as intelligent retries, conditional branching, and targeted recovery mechanisms. Real-world failure scenarios are used to illustrate how pipelines can detect issues, trigger remediation steps, and resume execution without full restarts or human intervention. The session also looks ahead to how AI-assisted anomaly detection can further enhance these systems by identifying unexpected patterns and enabling more proactive, resilient data workflows. ***Talk #3: What We Got Right (and Wrong) Building a 50-Source Data Platform on Airflow*** * **Speaker**: [Arnaud Caldow](https://www.linkedin.com/in/arnaud-caldow-384423142/), Senior Data Engineer at Collibra Collibra helps enterprises govern their data, but how does Collibra's own data team manage the data that powers the business? The answer is an Airflow-based platform that stitches together dlt, dbt, Kubernetes and Collibra's own product for governance -- all orchestrated through 87 DAGs serving 12 business domains. This talk traces a data point's journey through the stack: from API extraction via dlt pipelines running inside KubernetesPodOperator pods, through a layered dbt architecture where platform engineers standardize data and analysts build business models on top, into analytics outputs that serve multiple business teams, and finally back into Collibra Data Governance via reverse-ETL integration DAGs. Along the way, I'll share the patterns that emerged from operating this at scale: how we evolved from one-off custom pipelines to a reproducible framework that's documented well enough for AI subagents (or a new hire) to generate models from scratch, how our own Pod Operators let us test feature branches on shared environments, and how we're leveraging that same mechanism to migrate from Redshift to BigQuery (and from Airflow 2 to Airflow 3) without downtime. Behind the scenes, a 1Password-backed pipeline diffs credential hashes nightly, catching rotations before they break a DAG. **AGENDA** * **5:30-6 PM:** Arrivals, networking, food & drinks * **6-7:45PM:** Presentations * **7:45-8PM:** Networking

**Brews and Lose... Track of Time!** Bermondsey Beer Mile. Relaxed pace. Visit craft brewery tap rooms in ancient industrial London. It really is a lovely walk, lots of Victorian buildings, murals, art, etc. As with all our events, you **do not** need an ADHD diagnosis. Come as you are, meet nice, quirky people. We will attempt to visit several of the taprooms in a loosely sequential order. I strongly recommend having thirds or halves of a pint! Some of us will succeed. To keep you in sustenance, there will be assorted food places along the route.

**BOOK HERE**: https://sportas.co.uk/games/48732 **Game Description:** Social fun mixed and beginner friendly badminton session based in East London. Founded in 2024 delivering weekly badminton sessions 🏸 Please note even if session isn't full, there will attendees coming internally :) Find more about us at @sportingdllm (IG)! **Rules** Mixed doubles up to 21! always be friendly, respectful and match each other levels. We all started somewhere!

We playtest all sorts of tabletop games - strategic, silly, creative, or whatever (but not video games). Some games are almost done. Some are very early ideas. We test anything that will fit into 90 minutes. You don't need to bring a game - we always love to have new playtesters! Please let us know in the comments when you plan to arrive/leave and whether you are bringing a game or not. This helps us to plan the day better. The schedule is: 10am onwards - gathering, chatting 11am sharp - playing for 90 min ('slot 1') 12:30ish - break for food/chat 1pm sharp - playing for 90 min ('slot 2') 2:30ish - break for food/chat 3pm sharp - playing for 90 min ('slot 3') 4:30ish - finish up Often, we might hang around afterwards, to play some already-published games. We are strict on timings, so please try to arrive a few minutes before the session to limit disruption. You can just come for part of the day if you wish. The reason we have fixed timings for the 3 'slots' is to make it easier for folk to do so. Designers of all levels of experience are welcome! But if it's your first time, we ask that you don't bring a game and just spend some time learning how the group works. The group works based on reciprocation. If you expect to test your own game, make sure stay for long enough to play other games. As a general rule of thumb, you can expect to play one of your own games every third 90-minute session. So if you stay a whole day (3 sessions), you can expect to have one session to play your game(s). A good rule of thumb is that if you come all day, you will have one 90 minute session with two other playtesters in which to test your own games. It is sometimes possible to test games with more players. If your game requires 4 or more, please note that as standard you will be allocated half of a session (45 minutes). Pre-covid, we were getting unmanageable. As a result, we may have to limit attendees. This is a free-to-use venue, and we have to be mindful that other folk want to use the same space. Please note: This is an adults only event. We look forward to seeing you!

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
