**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

**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.

You can journal your thoughts, emotions, experiences… You can write a sentence, a paragraph, a page… But journaling doesn’t have to be a chore, it can be enjoyable and enlightening. It can deepen your self-awareness, help you gain clarity and add a sense of calm. Whether you’ve never tried it or you’ve done a spot of journaling in the past and fallen out of practice, join us to: * explore the why, the how and the art of journaling * get inspired to pick up your pen and start journaling **This is a free in-person 60-minute seminar.** **If you would like to make a voluntary donation, please click** [here.](https://www.innerspace.org.uk/donations/ "https://www.innerspace.org.uk/donations/") \* I consent to my submitted data being collected and stored.

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!

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

*Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

We are going to build together with all the CLIs! E will be doing it at Columbus Code and Coffee Agenda --- Hosted By James Power, Organizer Pete Gordon, Organizer Just a Software Guy in the age of the Internet.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. So please RSVP for a head count!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
