We're excited to be back and pleased to say this event is being sponsored by [pgMustard](https://pgmustard.com). On the talks front, we have **Anton Borisov and Vlad Bokov** from Fresha who will take us through how they recently upgraded their fleet with zero-downtime. We will then host our first ever debate, on a topic to be determined! WHERE Join us at **Doggett's Coat and Badge on 14 April from 18:30.** PROGRAM 18:30 Welcome 19:00 Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice (Anton Borisov and Vlad Bokov, Fresha) - abstract below 19:45 Sandwiches and bar snacks (paid for by our sponsor) 20:00 Debate — topic TBD ABSTRACT **Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice** Upgrading PostgreSQL across hundreds of production databases without downtime sounds impossible, especially when logical replication slots, Debezium CDC pipelines, and outbox event streams are in play. At Fresha, we faced exactly that: mission-critical workloads still on PostgreSQL 12, and no safe way to reach 17 without freezing the business. This talk walks through how we designed and automated a blue-green upgrade framework using logical decoding, controlled WAL overlap, and connector orchestration. We’ll dive into how Debezium connectors, replication origins, and PgBouncer pools were coordinated to guarantee continuity for both CDC and outbox topics, with rollback and dry-run modes built in. Attendees will learn practical techniques for: * Orchestrating zero-downtime Postgres major upgrades on RDS or self-managed clusters * Managing replication slots and Debezium connectors safely across clusters * Handling sequence alignment, WAL overlap, and connector state transitions * Designing reversible, testable database cutovers This is a practical session from real production experience: no magic tools, just PostgreSQL internals, Debezium, careful planning, and a few well-placed bash scripts. SPEAKERS **Anton Borisov** architects real-time data systems centered on PostgreSQL. At Fresha, he designs zero-downtime migrations, Debezium-based CDC pipelines, and overall data strategy integrating Postgres with Kafka and Flink. His work spans query planning analysis, partitioning and indexing, autovacuum and bloat optimization, and performance tuning under high-concurrency workloads. He also builds downstream lakehouse integrations with Iceberg, Paimon, and StarRocks. Anton publishes technical deep-dives on PostgreSQL internals, streaming infrastructure, and production reliability at medium.com/@borzoniusy **Vlad Bokov** is a Staff Engineer at Fresha working on systems behind activity feeds and communication between partners and customers. He deals with what breaks at scale: PostgreSQL under heavy write load, WAL bottlenecks, replication issues, Kafka pipelines, and zero-downtime migrations. Most of his work is about making production systems behave: fixing what is slow, unstable, or too expensive, and making trade-offs that hold up under pressure. He works across Snowflake, StarRocks, PostgreSQL, Elasticsearch, and Redis, and is currently exploring newer streaming approaches, including Apache Fluss, for real-world workloads. *** THE OFFICIAL BITS The meet-up abides by [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/).

**Bookable via our website ➡️** [https://www.thegoodlifecentre.co.uk/events/follow-on-woodwork-4/](https://www.thegoodlifecentre.co.uk/events/follow-on-woodwork-4/) ⋆⋆⋆ Directed at those people who have completed one of our longer woodwork courses, or those with confident woodwork skills, we offer an eleven-day week opportunity to build an individual project. During this course, run by experienced carpenter/joiner/furniture maker Ruth Thomson, you will learn how to manage a practical project from sketching it, making a technical drawing, writing a cutting list, costing, marking out and construction to produce a piece of wood furniture. The group will visit a timber yard to learn how to select lengths of soft woods. You will learn the safe use and versatility of a router, a biscuit jointer, a jigsaw and other power tools as needed and learn when and how to make jigs to help fabricate accurate shapes. Using basic workshop machines including a bandsaw and a belt sander, as well as classic hand tools, you will cut and assemble and then learn how to sand, glue and finish your project to completion. We are happy to discuss your personal project if you already have something in mind. There is a size limitation due to time constraints and project storage. Call Alison on 0207 7607613 or send a photo or sketch to info@thegoodlifecentre.co.uk Each learner will pay for their own materials. We can take delivery of timber if externally sourced. Please note that we cannot handle MDF in the workshop as the dust requires special extraction and respiratory equipment. Plywood or solid timber will be pre-machined for you on our planer thicknesser and table saw.

The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken). Example challenges for the coding dojo are listed on this website: http://www.londonclojurians.org/code-dojo/ Various past exercises have been loaded to [https://github.com/ldnclj](https://github.com/ldnclj/lisp1.5/blob/master/src/lisp1/5.clj) # Approximate schedule: 18:40 Doors open and start collecting suggestions 18.45 Pizza should have arrived 19:00 Quick intros and vote on suggestions 19:15 Break out into groups and start practising 20:45 Gather together for a quick show and tell # What should I bring? We organise into small groups, so if you have a laptop with a working Clojure environment please bring it along (there are lots of online Clojure environments, so you can just use your browser too). # How do I get in to the building? At the glass doors press the buzzer to inform the security guard you are here. Say you are here for the event on the first floor. Is there way to talk with the Clojure community? Why yes. The Clojurians Slack channel is full of friendly people who love to try and help. People based in London are often in the #clojure-uk channel. Sign up for a free account to the Clojurians Slack community via http://clojurians.net/ What is Clojure? Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

**Bookable via our website ➡️** [https://www.thegoodlifecentre.co.uk/events/woodwork-step-up-low-wood-stool-6-evenings-4/](https://www.thegoodlifecentre.co.uk/events/woodwork-step-up-low-wood-stool-6-evenings-4/) ⋆⋆⋆ This lovely six-week evening course is another charming project from our cherished Edwardian instructional woodwork manual, ‘Carpentry for Beginners’. The projects in the book are perfect for learning basic woodwork skills and we have refined the instructions to incorporate a modern craft construction. This classic ‘child’s stool’ is a handy ‘hop up’ you can use if you have shelves you can’t reach at home and small ones can reach the sink by standing on it. It measures 40cm x 22cm x 26cm high. We use a redwood pine wood that releases a heady and uplifting scent when cut, chiseled, and planed. Even if you have never used any tools, our expert makers will teach you the processes you will need to take home a future heirloom along with a very special sense of satisfaction that comes with crafting by hand. Over six evenings you will learn how to measure and mark timber accurately, use a chisel and a vintage ‘Granny’s tooth’ hand router to cut out grooves to house the legs into the sides of the stool. By the time you have finished your useful step-up stool, you will have become familiar with many of the basic woodworking hand tools and increased your confidence to go on and do more general woodwork at home. All use of tools and materials included.

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Haoyi Li, Martin Durchov and Adam Deegan. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Haoyi Li: Scripting on the JVM with Scala 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan, vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Martin Durchov: ScalaMeta: Treating Scala code as data 8:10pm - 🗣️ Adam Deegan: Practical Java Interop for Scala Effect Systems 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event may have a live stream** Watch this space for more details. **🗣️ Haoyi Li: Scripting on the JVM with Scala** This talk will explore the use of Scala as a scripting language, replacing the Bash and Python scripts common throughout the industry. ⭐ Haoyi Li ⭐ Li Haoyi graduated from MIT with a degree in Computer Science and Engineering, and since then has been a major contributor to the open source community. His projects have over 10,000 stars on Github, and are downloaded over 20,000,000 times a month. Haoyi professionally built distributed backend systems, programming languages, high-performance web applications, and much more. **🗣️ Martin Durchov: ScalaMeta: Treating Scala code as data** Scala source code is usually something we write and hand off to the compiler. But what if we could parse it, inspect it, build it, and transform it all from regular Scala code? ScalaMeta is the metaprogramming library that makes this possible, and it underpins a lot of modern Scala tooling ecosystems: Scalafmt, Scalafix, and Metals are all built on it. In this talk we'll look at what ScalaMeta is, how its AST models Scala programs, and the core operations it provides: parsing, quasiquotes, tree traversal and more. We'll then turn to how we use it at Quantexa, where it powers code generation for our clients. Along the way we'll cover practical patterns that make code generation manageable at scale, and the rough edges you should know about before adopting it yourself. ⭐ Martin Durchov ⭐ I graduated from UCL in 2019 with a MSci in Theoretic Physics and started work in TxOdds, a small company focused on ultra-fast data streaming and processing, where I first encountered Scala, working with Typelevel libraries. Since January 2025 I have been working at Quantexa in the team responsible for data ingestion and processing also relying heavily on the Scala functional libraries and ScalaMeta. **🗣️ Adam Deegan: Practical Java Interop for Scala Effect Systems** Interfacing with a highly autonomous Java library in a functional manner is difficult. In this talk we'll explore the ways in which we've approached this; issues we found along the way; and the trade-offs between purity and pragmatism when there's a runtime which isn't yours to control. ⭐ Adam Deegan ⭐ Adam Deegan graduated from the University of Bristol with a degree in Computer Science in 2021 and has worked at Quantexa ever since. He started off as a Data Engineer and moved into software engineering a couple of years ago, working on the addition of a case management capability. His first true programming love was making Minecraft mods. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?
