**Main Talks**
1. **Agentic Workflows for Data Engineers: How AI Agents Are Changing Our Daily Work** - [Yusuf Ganiyu](airscholar@gmail.com)
Last month, I debugged a critical pipeline failure in 4 minutes that used to take 30. The difference? An AI agent that understands my data infrastructure.
This isn't about replacing data engineers, it's about eliminating the toil that keeps us from high-value work. In this talk, I'll share practical experiments with agentic workflows from my work at AstraZeneca and teaching 20,000+ students at DataMasteryLab.
We'll explore:
* What agentic workflows actually are (beyond the hype)
* Live demo: AI-assisted pipeline debugging with LangGraph
* Practical patterns: Schema evolution, data quality monitoring, self-healing pipelines
* The feature engineering bridge: Helping data scientists love you
* What AI still can't do (and why that matters)
Whether you're skeptical about AI hype or already experimenting, you'll leave with concrete patterns you can implement in your pipelines next week.
2. **Explore the Kingdom - Cursor the Data Engineer** - [Jethro Reeve](jethro.reeve@gmail.com)
I built [explorethekingdom.co.uk](http://explorethekingdom.co.uk/ "http://explorethekingdom.co.uk") over Christmas using Cursor with Opus-4.5 and GPT-5.2 for the data engineering and UI.
I've pulled \~15 Government data sources and have them represented on a map of the UK. This kind of data aggregation tool sells for thousands to niche consultancies. I built it while playing Minecraft on Boxing Day.
What would you use it for? (Why) Is the software world so slow to catch up with the capabilities of vibe coding?
**Lightning Talks**
1. **Github Codespaces for Data Analysis with Python - [Stelios Christodoulou](stelios.xristodoulou@gmail.com)**
2. **TBC**

Error-handling in C++26
This month we have a visiting speaker from think-cell, Sebastian Theophil, who will talk to us about error handling in C++26 (with sprinkles of C++23).
We also have space for a shorter talk, or lightning talks. If you would like to speak - even for just five minutes, please drop something into cppldn.uk/speak.
**think-cell** will also be supporting the group by providing pizza and drinks - thanks **think-cell**!
Thanks, also, to **Maven Securities** for hosting us again, this month.
**As usual we'll need your full name for the door list, so we'll be asking for this on registration** (as this may be different to your username).
This data will only be used for the door list/ registration and not published anywhere or used for other purposes.
If you'd like to speak at a future event please get in touch at [cppldn.uk/speak](http://cppldn.uk/speak).
**Here's the approximate schedule:**
**18:30** *Doors open*
**19:00** "Intro and news" - *Phil Nash*
**19:10** *"compile_assert - Compile time C++ assertions" - Jonathan Grant*
I present compile_assert(expression, message), a new C++ keyword proposal for enforcing assertions at compile time within ordinary (non-constexpr) functions.
compile_assert provides advanced asserts at compile time, not runtime. Used for bounds checking, parameter validation and data validation at compile time. All three major compilers (GCC, Clang, MSVC) are supported with a sample implementation. The example implementation does this by using GCCâs attribute error which works with Clang.
**19:25** "Compile-Time Data Layout Transformation with C++26 Reflection" - *Arturs Kalnins*
Weâll use C++26 static reflection and injection to convert an AoS into a SoA at compile time, live on the latest GCC, with zero macros and zero boilerplate.
**19:40** *break*
**20:00** "To Err is Human: Robust Error Handling in C++26" - *Sebastian Theophil*
A walk through the new error handling features in C++26 â including \`std::expected\`, \`std::stacktrace\`, contracts, and more â and how they can help us write more robust, maintainable code.
**21:00** *Conclusion, and moving on somewhere else*

Underwater Rugby training
You can expect a friendly introduction to the sport, but in all honesty you will dive in at the deep end to learn UWR.
Please bring swimwear and an open mind and expectation to have fun. We can lend an UWR hat, snorkle, mask and fins. Although if you have them already it is better to bring your own.
Expect to swim, dive to 4m depth, hold your breath longer than you thought you could, be involved in drills and games. It is full contact and you will be wrestling other players to take the ball and pass to your team or score a goal.
Please get on touch with questions or intent to attend prior to session so that we can support with kit etc.
Cloud Native London, March 2026
Hi folks!
Welcome to our March Cloud Native London meetup! Join us to hear from our three great speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube!
6:00 Pizza and drinks
6:30 Welcome
6:45 Predictable Systems in an Unpredictable World (Behrad Babaee, Aerospike)
7:15 Observability with HAProxy: detecting what is not working and why (Baptiste Assmann, HAProxy Technologies)
7:45 Break
8:00 eBPF: Revolutionizing Cloud-Native Security (Alam Ahmed)
8:30 Wrap up
See you there!
Cheryl (@oicheryl)
**Predictable Systems in an Unpredictable World (Behrad Babaee, Aerospike)**
Modern systems are challenged by volatility. Traffic patterns shift without warning, workloads evolve continuously, and failures are no longer exceptional events. In this environment, average performance is meaningless. What matters is whether systems behave predictably when conditions change.
This session explores how system design choices determine behavior under volatility. We will discuss why many modern architectures rely on fragile assumptions about steady-state workloads, cache locality, or predictable growth, and how those assumptions break down in real production environments. Through concrete examples and architectural discussion, we will examine what it means to design systems that remain predictable as load, access patterns, and scale evolve.
The goal is not to showcase tools or benchmarks, but to build a shared mental model for thinking about predictability as a first-class system property.
*Behrad Babaee is a software engineer who leads Product Marketing at Aerospike, shaping positioning and go-to-market strategy for real-time data systems in the AI era.*
*He began his career building scalable, distributed applications for organisations including Barclays and Credit Suisse, before moving into architecture and field leadership roles at Aerospike and DataStax.*
*Today, he combines deep engineering expertise with strategic product leadership, focusing on how organisations design systems that remain predictable, resilient and performant under real-world volatility.*
**Observability with HAProxy: detecting what is not working and why (Baptiste Assmann, HAProxy Technologies)**
Is it the network, the app, or the database? In complex microservices environments, "mean time to innocence" is a critical metric for platform engineers. HAProxy sits at the convergence of these traffic flows, providing a unique vantage point to answer the ultimate observability question: "WTF is going on?".
We'll do a deep dive into the metrics that matter, so you can detect anomalies before users complain. You will learn:
* The difference between monitoring and observability in a reverse proxy context.
* How to access HAProxyâs detailed logs, stats, and stick-tables.
* How to analyze the "life of a request" using precise timers to pinpoint latency sources.
* How to use HAProxyâs observability features to fix real-world issues (demo)
* How HAProxy Fusion provides centralized observability and automation for enterprise deployments at scale.
*Baptiste Assmann is Director of Product at HAProxy Technlogoes. He spent his carreer on networking and high performance architecture. Today, he plays a key role on HAProxy's ecosystem evolution: from bare metal to Kubernetes and from load balancing to advanced security at scale and always looking forward for what's next!*
**eBPF: Revolutionizing Cloud-Native Security (Alam Ahmed)**
eBPF: Revolutionizing Cloud-Native Security from the Kernel Up
Cloud-native architectures have fundamentally broken traditional security models. While 67% of organizations now delay deployments due to Kubernetes security concerns, conventional tools remain blind to the dynamic, ephemeral nature of containersâoperating from the outside looking in, missing critical kernel-level threats until it's too late.
This session reveals how eBPF (extended Berkeley Packet Filter) is transforming cloud-native security by moving visibility and enforcement directly into the Linux kernel. Through real-world case studies from Meta, Google, and Cloudflareâwhere eBPF processes billions of packets per second and mitigates multi-terabit DDoS attacksâyou'll discover how this technology delivers 10x performance improvements with <1% CPU overhead.
We'll explore the production-ready CNCF ecosystem (Falco, Tetragon, Cilium) and demonstrate practical security observability patterns: process execution monitoring, network correlation with Kubernetes context, file integrity tracking, and syscall anomaly detection. No kernel modules. No code changes. Complete visibility.
Whether you're battling container escapes, cryptojacking, or compliance gaps, this talk provides the architectural blueprint for security that matches the speed and scale of cloud-nativeâwithout sacrificing agility.
*Alam Ahmed is a Junior Cloud & DevOps Engineer with NOC operations experience and a focus on cloud security. He has spoken at Elastic London and Yorkshire DevOps on Security as Code practices, contributes to open-source projects including Envoy AI Gateway, and is passionate about kernel-level observability and cloud-native defense.*

Hackathon: Agents & Knowledge Graphs (LangChain x SurrealDB)
## \*Please note - to be admitted to this event you must register for approval here: [https://luma.com/lcsqwmf3](https://luma.com/lcsqwmf3)
This weekend hackathon brings together LangChain and SurrealDB to explore how agents can move beyond demos by grounding themselves in structured, persistent context.
As agentic systems become more autonomous, their biggest failure mode isnât model capability - itâs context. Agents struggle with accuracy, consistency, and reasoning when memory is shallow or unstructured. Knowledge graphs provide a powerful way to represent relationships, state, and history, enabling agents to reason over how things connect, not just what text is retrieved.
Over the weekend, youâll build practical agent projects using the LangChain ecosystem, with a strong emphasis on knowledge graphs and real-world retrieval workflows, using SurrealDB as a unified data layer for graph, document, vector, and temporal data.
Youâll also have plenty of time to connect with both the LangChain and SurrealDB communities in London, collaborate with other builders, and get hands-on support from mentors.
***
## Schedule
**Friday**
* 18:00 - Doors open, check-in, pizza & drinks
* Hackathon kickoff, team formation & briefing (time TBC)
**Saturday**
* All day - Build, iterate, mentor support (details TBC)
**Sunday**
* Final build, demos & judging (details TBC)
* 15:30 - Closing, winners & wrap-up
Full challenge details and rules will be shared ahead of the event.
***
## What youâll work on
* Agent workflows built with LangChain
* Knowledge graphâdriven context and memory
* Hybrid retrieval patterns (vector + graph)
* Persistent agent state and evolving context
* Practical, production-oriented agent use cases
***
## Prizes
* Swag and LangSmith credits from LangChain
* Swag from SurrealDB
***
## Why attend?
This is a hands-on opportunity to build credible agent projects in a single weekend, learn production-oriented patterns, and explore how structured context improves agent accuracy and reliability. Youâll collaborate with experienced builders, get direct support from the LangChain and SurrealDB teams, and connect with the wider London agent and AI engineering community.

"The Enchanted Greenhouse" by Sarah Beth Durst
Come join us for coffee at Matari Coffee to discuss our March book, "The Enchanted Greenhouse"!
Book description:
Terlu Perna broke the law because she was lonely. She cast a spell and created a magically sentient spider plant. As punishment, she was turned into a wooden statue and tucked away into an alcove in the North Reading Room of the Great Library of Alyssium.
This should have been the end of her story . . . Yet one day, Terlu wakes in the cold of winter on a nearly-deserted island full of hundreds of magical greenhouses. Sheâs starving and freezing, and the only other human on the island is a grumpy gardener. To her surprise, he offers Terlu a place to sleep, clean clothes, and freshly baked honey cakesâat least until sheâs ready to sail home.
But Terlu canât return home and doesnât want toâthe greenhouses are a dream come true, each more wondrous than the next. When she learns that the magic that sustains them is failingâcausing the death of everything within themâTerlu knows she must help. Even if that means breaking the law again.
This time, though, she isnât alone. Assisted by the gardener and a sentient rose, Terlu must unravel the secrets of a long-dead sorcerer if she wants to save the islandâand have a fresh chance at happiness and love.
CBusData - Discover the Power of Window Functions
Window functions have nothing to do with the Windows operating system but provide a âwindowâ to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems:
* Using running totals
* Performing operations in intervals
* Identifying data gaps and islands
* Performing aggregates without losing detail
Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
Go Build & Learn
Meeting @ Improving's office in Downtown Columbus, near Cosi. Parking is paid, food & drink are free!
This time we're hanging out after the long winter break. We are going to look at a group-member's project used to help learn the fundamentals of Go, and if time allows, we can take a look at how we like to build Go projects using AI.
