High Scalability Computing

**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.

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

This is a **theatre** and **livestream** talk from the **Royal Institution of Great Britain.** Join a team of forensic scientists for an immersive, demo-filled event taking us through the process of analysing and solving a crime, plus a look at the new technology changing the way DNA is analysed. **ADVANCE BOOKING AND PAYMENT IS REQUIRED FOR THIS TALK.** **More details and booking instructions on the RI web site:** **[https://www.rigb.org/whats-on/forensics-how-solve-crime](https://www.rigb.org/whats-on/forensics-how-solve-crime)** **SUMMARY** We are used to media depictions of forensic science, but what does the real process look like? And how are new technologies changing the face of modern forensics? In this unique event, a team of forensic specialists from around the UK will come together to guide you through a fictional case. Discover how the **SCAnDi** project could revolutionise the world of forensics by allowing scientists to trace DNA from a single cell, and therefore “unmix” the messy DNA profiles of multiple people often found at crime scenes. Scientific investigation of a crime involves a multidisciplinary team, and through the use of intricate recreation crime scenes and demonstrations, this event will explore how these individuals can come together to uncover crucial evidence. Ranging from DNA analysis to soil science, you'll have the chance to discover real forensic science used to solve crimes. **This event will cover sensitive material which some may find upsetting, including physical violence, sexual assault, death and suicide. It is suitable for those aged 16+.** This is a theatre and livestream event for an adult audience, where the speakers and audience in our Theatre are joined by our audience online. **The livestream will go live around 7.25pm, and the talk will begin at 7.30pm. If you register but miss the livestream, the video will be available to you via the same link for two weeks after the event date.** For more information on livestreams, see the information below, or [visit our FAQs page](https://www.rigb.org/whats/faqs-ri-livestreams).
