NewSQL

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\. In my free time\, I'm a handball\, agility and movement coach for various ages and teams\, next to spending time with the family and on the house\. **Note** We will again take notes who signs up and does not show up. This information will be used to provide seats to others at future events. Plain and simple: please only sign up if you plan to attend.

**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** *[Qase](https://qase.io) is presenting the **eleventh** Meetup on Quality Engineering in Berlin.* *This time, we’re bringing you three deep-dive talks — all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Mitesh Patel\, Technical Consultant \- Scientific Instruments @ Altum Solutions: *Food QA: Testing Tasting*** On this fine evening, we shall enjoy some food … and also learn why we enjoy it. Because tasting is really a form of testing for our brains — wetware QA in essence. But how do we reformulate this wetware testing into those familiar realms of software and hardware testing? It is not as simple as exchanging taste buds for test suites and bites for bytes. Just ask Big Food which spends billions on this same question: How can computers do taste tests like humans? Guided by the example of an ML/AI-powered scientific instrument for chemical analyses, namely, a spectrometer, this session addresses this question and explores the broader topic of QA in the food industry. Discover how food companies scale testing across scientific software, device hardware, and food/human wetware. So grab a spoon for this insider scoop on QA for food. **2\. Vitaly Sharovatov\, developer advocate @ Qase: *QA Myths Busting: A Practical Guide to Higher Quality*** Have you ever felt the urge to increase the amount of testing or hire more testers, thinking it would improve product quality? As a tester, have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers? Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. In this talk, I will present the myths I once believed, explain the dangers they pose to both teams and products, and demonstrate how they should be debunked and overcome. **3\. Asya Isakova\, Co\-Founder @ TECH_Connect: 𝘌𝘢𝘳𝘯 𝘛𝘳𝘶𝘴𝘵\, 𝘒𝘦𝘦𝘱 𝘠𝘰𝘶𝘳 𝘑𝘰𝘣** The job market is wild: it’s hard to get hired, and sometimes even harder to stay hired. In a new role (or a new team), one of the fastest ways to reduce uncertainty and accelerate collaboration is to build trust quickly. But how do colleagues and managers decide you’re trustworthy? It’s rarely just about closing Jira tickets or moving cards on a Kanban board. People assess trust through patterns of behavior: what you do, how consistently you do it, and how do you act towards others. In this talk, you’ll learn an evidence-based approach to building trust at work using three practical components: integrity, reliability, and benevolence. We’ll unpack what shapes people’s trust judgments (including context, risk, and prior experiences) and translate research into concrete behaviors you can apply immediately: especially in multicultural and cross-functional teams.

All are welcome. Whether you are new to Berlin, have lived here for a long time or are just passing through. Come on a Thursday, enjoy a drink and have a good time, meet new people and have interesting conversations with us. The place is wonderful, the first cocktail bar in Prenzlauer Berg. The offer only for Meetup members is Aperol Spritz for 6 € the whole evening. Now takes place on Thursday again. :)

In March we welcome [Valentin Churavy](https://github.com/vchuravy) to talk about the [Julia frontend](https://julialang.org) for LLVM.

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.

Actual Wine from glass bottles with corks and everything. **Wine**: Tastings will be $15 for four samples as always. And you are welcome to bring a bottle of your favorite wine to share with others. Participation in the wine tastings is optional. But since you’re going, I will buy enough wine to cover you. If you bring your own wine and do not participate in the tasting you will only pay $10 to cover the door charge. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. **Glasses**: …will be provided. Please note that after the wine tasting, the glasses need to be returned to the boxes at the service table. Please be gentle, our glasses are fragile. Uh, they are made of glass! **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **Extra Wine**: After everyone has had their samples, we remove the pouring spouts and any remaining wine is poured freely to whomever wants it. I hate having leftover wine. **Queen of Hearts**: The Queen of Hearts raffle is a fundraiser for the club and a Barnum and Bailey type extravaganza - minus the dancing ponies, clowns, and actual circus. Bring your ***cash*** as the Queen does not accept American Express or other plastic. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host*
