Join us at our first event of the year at [The Information Lab](https://www.theinformationlab.co.uk/) on the historic Watling Street in the City of London 🙌
We will be kicking off 2026 by delving into the topic of real-time data with our speakers - Sam, Nicoleta & Anton. We are running this event in collaboration with **[Confluent](https://www.confluent.io/)**.

**6pm:** Doors Open

**6:30pm:** Talks Start

🗣️The Speakers🗣️

***Load-In to Lights-Out: Data Engineering the World's Biggest Tours and Live Events***
***Sam Malcolm,*** ***Head of Architecture & Engineering at Centrus ([Sam's Linkedin](https://www.linkedin.com/in/sam-m-00b19a110/))***
**Sam’s** session dives into lessons from large-scale live event data systems—handling over **10 billion data points per second** for global tours like Beyoncé, Coldplay, and Glastonbury. He connects the extreme demands of real-time analytics and high-performance networking to modern cloud data practices, showing how the same principles of **speed, resilience, and precision** apply when designing reliable, scalable data platforms today.

***Should I Stream or Should I Join: From Regular to Delta Joins in Apache Flink***
***Nicoleta Lazar, Senior Data Engineer at Fresha & Anton Borisov, Principal Engineer at Fresha ([Niloceta's LinkedIn](https://www.linkedin.com/in/nicoleta-lazar-921a6864/) , [Anton's LinkedIn](https://www.linkedin.com/in/anton-s-borisov/))***
Joins in the streaming world are where the fun stops and the tradeoffs start. State that grows forever, latency that spikes unpredictably, watermarks that never quite behave, every Flink developer has war stories about this.
In this session, Anton Borisov and Nicoleta Lazar break down the join landscape in Apache Flink:

→ Regular joins and the state explosion problem
→ Interval joins: when they work, when they don't
→ Temporal joins and the versioned table dance
→ Lookup joins: the escape hatch and its hidden costs
→ Delta joins: the new kid and how Fluss enables them, and why it matters

Talks finish by **8pm** and there will be a break between the talks. Afterwards, we may head to a pub to continue chatting.
