Ready to flex your architectural muscles… with a new twist? Join us for our first **AI-Enabled Architectural Kata**, where we'll tackle a real design challenge together, using generative AI as a collaborator in the architectural process. Small teams will work through a complex scenario, but this time each team gets a unique **AI collaboration role** that shapes how they interact with AI during the session. Expect lively debate, creative solutions, plus an honest reflection on where AI helps and where human judgement still reigns supreme. **Mark your calendars for Thu, Mar 5,** and join us at **Thoughtworks Event Space** for an engaging evening dedicated to software design and architecture. Whether you're a seasoned architect, an AI-curious developer, or just passionate about software design, this meetup is the perfect platform to share, learn, experiment with new ideas and meet passionate people. **Event Schedule** * **18:15** – Doors open for snacks, drinks, and socialization * **18:45** – Introduction * **19:00** – **AI-Enabled Architecture Kata**: Small teams' work session * **20:30** – Presentations by teams **❓ What is an Architectural Kata?** Inspired by the concept of “Code Kata,” Architectural Katas are exercises that allow architects to practice their skills in a real-world scenario. It's about honing our craft in software design through practical, hands-on challenges in small groups. Read more about Architectural Katas on [Neal Ford](https://nealford.com/katas/about.html)'s website or on the [original Katas site](https://www.architecturalkatas.com/) by Ted Neward. **What makes this one AI-Enabled?** Building on the classic Architectural Kata format, this edition adds a new dimension: **AI as a team member**. Each team receives a unique role card that defines how they collaborate with AI during the session. The goal isn't to see who can prompt the best. It's to explore together how AI changes the way we think about, discuss, and communicate software architecture. **What to bring** Please have access to at least one AI tool on your phone or laptop (Claude, ChatGPT, Gemini, or similar). We'll provide a short prompting cheat sheet for architectural AI collaboration to get you started. No prior experience with AI for architecture work is needed! **Venue** **Thoughtworks Event Space**, Revaler Str. 31, 10245 Berlin *(Please note that this is a different entrance from the Thoughtworks office located at Revaler Str. 29)* **Sponsored by Thoughtworks** A big shout-out to [Thoughtworks](https://www.thoughtworks.com/) for sponsoring our event and supporting our mission to foster a tight-knit community of software design practitioners. **Code of Conduct** We adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/) to ensure a welcoming and respectful environment for all participants. **Spread the Word** We believe the more, the merrier!

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

Zalando is graciously hosting us for our first Meetup in 2026. And we are doing it a bit different: we have two rooms, and two talks in parallel. This gives you the opportunity to choose between two talks, for a total of four talks. This year, we’re especially happy to welcome Amazon Web Services as the food sponsor for our meet-up. Thanks to their support, our community can enjoy great conversations over great food — making the evening not only insightful, but also delicious. Meet the AWS experts Sikandra Chaudhary, Daria Aleshkova, and Narendra Tawar. Narendra will be delivering a talk on PostgreSQL and AI, sharing practical insights and real-world experience. We truly appreciate AWS’s commitment to supporting local tech communities and helping us create a warm, welcoming atmosphere for everyone. **PLEASE BRING YOUR PHOTO ID** **USE THE MAIN ENTRANCE TO BHW ON THE SIDE OF UBER ARENA** **Agenda** Two sessions run in parallel in rooms codenamed "Auditorium" and "Festival" **18:30** \- doors open: registration\, networking\, and drinks **19:00 - 19:05** Auditorium, "Event intro" by Sergey Dudoladov, Senior Database Engineer in Zalando. **Auditorium: Track A** **19:10 - 19:55** "How we made WarehousePG Open Source (again)" by Andreas 'ads' Scherbaum, a WarehousePG Principal Engineer at EDB and a Founding Member of PostgreSQL Europe **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups" by Tudor Golubenco, CTO of Xata **Festival: Track B** **19:10 - 19:55** "The Role of PostgreSQL in the AI World" by Narendra Tawar, Sr Database Specialist SA, AWS **19:55 - 20:15** Networking, Q&A, and pizza **20:15 - 21:00** "Modernizing Postgres Communication with Hackorum", by Kai Wagner, Percona **21:00 - 22:00 Networking, Q&A, and pizza** **22:00 - The End** **Abstracts** **How we made WarehousePG Open Source (again)** WarehousePG is an Open Source fork of Greenplum Database, which by itself is a fork of PostgreSQL. The project was born after the upstream project was made closed source. This talk gives a quick overview of the history of both projects, which already spans more than two decades. We then dive into the reasons for creating a fork, and all the stumbling stones we had to pass in order to make this project open source again. We also talk about the challenges of CLAs (Contributor License Agreements) and what implications the PostgreSQL and Apache Licenses have for the project. Speaker: Andreas 'ads' Scherbaum **The Role of PostgreSQL in the AI World** As artificial intelligence (AI) continues to revolutionize industries, the need for robust, scalable, and efficient data management solutions has never been greater. PostgreSQL, with its extensibility, performance, and advanced data capabilities, plays a crucial role in enabling AI-driven applications. This talk explores how PostgreSQL supports AI workloads, from managing vast datasets and integrating with machine learning frameworks to leveraging extensions like PostgreSQL ML, TimescaleDB, and JSONB for AI-ready storage and querying. Attendees will gain insights into best practices for using PostgreSQL in AI pipelines, optimizing performance for AI inference, and harnessing the power of open-source innovation to drive intelligent decision-making. Whether you're a data engineer, AI researcher, or PostgreSQL enthusiast, this session will showcase why PostgreSQL is an essential component in the AI ecosystem. **From 20 seconds to sub-second: Speeding up CloudNativePG wake-ups** CloudNativePG (CNPG) is a popular and battle-tested operator for running Postgres on top of Kubernetes. At Xata, we’ve been using CNPG and extending it in several different directions. One of them is implementing a scale-to-zero plugin: clusters hibernate when inactive and they wake up automatically when new connections are created. After adding scale-to-zero, we’ve faced the challenge that the CNPG wake-up from hibernation is rather slow.This is an optimization story about how we reduced the wake-up times from 20+ seconds to under one second. Speaker: Tudor Golubenco **Modernizing Postgres Communication with Hackorum** In 2026, the debate over whether mailing lists are still "state of the art" continues to divide developers. While some view them as relics, we cannot neglect the unique benefits of their decentralized, archival nature. Rather than fighting over platforms or ignoring the friction, Hackorum asks a simpler question: Why not just improve the user experience? Hackorum transforms the daunting mailing list "firehose" into a modern, forum-style interface without breaking the underlying email culture. It is designed to lower the barrier for new contributors while providing power tools for veterans: Seamless Integration: Real-time sync between mailing lists and daily sync of the Commitfest status. Modern UX: Per-message read tracking, tagging, and contributor profiles. Enhanced Coordination: Shared notes and mentions to streamline complex reviews. We have to stay open minded and willing to expand our horizon and as such Hackorum is rapidly evolving. While our roots are in development, we are currently expanding to include broader mailing lists like -general and -docs. Our goal is to make the entire Postgres ecosystem more accessible and usable for everyone. Join us for a demo of the latest updates and help us shape the future of Postgres communication. Speaker: Kai Wagner **About the speakers** **Andreas Scherbaum** has been working with PostgreSQL since 1997. He is involved in several PostgreSQL related community projects, member of the Board of Directors of the European PostgreSQL User Group and also wrote a PostgreSQL book (in German). Since 2011 he was working for EMC/Greenplum/Pivotal and tackled very big databases. Until 2024 he was doing the same - but with maybe even more and bigger databases - for Adjust GmbH in Berlin. Now he's working at EDB as WarehousePG Principal Engineer and is helping customers with even larger databases. **Tudor Golubenco** is the CTO of Xata, a Postgres platform with branches and zero-downtime, reversible schema changes. Before Xata, Tudor worked as a tech lead at companies like Elastic and Oracle. **Narendra Tawar** \- Sr Database Specialist SA I am accomplished database professional with 21 years of comprehensive experience across Oracle, PostgreSQL, Microsoft SQL Server, and MySQL environments, with specialised PostgreSQL expertise since a decade. Currently serving as a Senior Data Migration Specialist at AWS, I architect and execute complex enterprise migration strategies while actively expanding into Generative AI technologies to enhance migration efficiency and optimize data workflows. My core competencies include database architecture, performance optimization, migration planning, and cross-platform data integration, combining decades of hands-on experience with modern cloud methodologies to deliver scalable, reliable data solutions that bridge traditional database principles with emerging AI capabilities. **Kai Wagner** \- I’m Kai\, a Senior Engineering Manager at Percona with almost two decades of "bleeding" open source in my DNA\. From the Linux Kernel and Ceph at SUSE to leading PostgreSQL development today\, my career is built on a foundation of transparent communication and community\-driven innovation\.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.

Window functions have nothing to do with the Windows operating system but provide a “window” 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.

Join other experienced and aspiring agile coaches and professionals to: * develop and practice your coaching skills in a peer-to-peer environment * share current successes and challenges in your work environment and get support from each other * learn from each other, build better relationships and experiment with new ideas
