Hello everyone! Join us for an Apache Kafka® x Apache Flink® meetup on **Apr 9th from 5:30pm**, in Melbourne! The address, agenda, and speaker information can be found below. See you there! **📍Venue**: 394 High Street Northcote, Victoria 3070 \*\*\* **🗓 Agenda:** * 5:30pm: Doors open * 5:30pm - 6:00pm: Pizza, Drinks, and Networking * 6:00pm - 6:30pm: Chad Harris, Solutions Architect, Factor House * 6:30pm - 7:00pm: Stephen Ermann, Senior Customer Success Technical Architect * 7:00pm - 7:30pm: Additional Networking \*\*\* **💡 Speaker:** Chad Harris, Solutions Architect, Factor House **Talk:** Things that go bump in the night: Kafka Operational Issues and How to Survive Them **Abstract:** Most Kafka talks focus on how things should work—this one is about what actually happens in production. We’ll walk through real-world operational issues encountered with Apache Kafka and its clients, from subtle misconfigurations to full “why is everything on fire?” moments. Along the way, we’ll break down how to identify what’s going wrong, which signals actually matter, and how to approach debugging when the system doesn’t behave the way you expect. This talk will also touch on observability, common failure patterns, and practical mitigation strategies you can apply immediately. Expect a mix of technical deep dives, debugging workflows, and a few war stories (including some questionable decisions and log-staring sessions). If you’ve ever wondered whether it’s just you? It's not! **Bio:** Chad Harris is a streaming data specialist and Solutions Architect at Factor House, where he helps organisations design, scale, and operate Apache Kafka platforms using industry-leading tooling. With experience scaling Kafka across organisations ranging from small startups to some of Silicon Valley's largest companies, Chad has been working with Kafka since its early days. He brings deep expertise across both real-time streaming and data-at-rest systems, with a strong focus on practical, production-ready architectures. \-\-\-\-\- **💡 Speaker:** Stephen Ermann, Senior Customer Success Technical Architect **Talk:** From Lag to Smooth Sailing: How Queues for Kafka (KIP-932) Fix Slow Consumers **Abstract:** Slow or bursty consumers are one of the most common reasons Kafka applications end up fighting lag, over-provisioning, and operational fire drills. Traditional Kafka consumer groups work brilliantly for high-throughput stream processing, but they can make it hard to serve heterogeneous consumers, apply backpressure cleanly, or guarantee fair access when some consumers fall behind. In this talk, we’ll explore **Queues for Kafka**, the new KIP-932 feature that introduces native queue semantics on top of Kafka’s battle-tested log foundation. We’ll look at how queues decouple producer and consumer throughput, isolate slow consumers without penalising fast ones, and provide more predictable delivery and scaling behaviour for “task” and “work queue” style workloads. You’ll walk away with: * A clear mental model of how Kafka queues differ from topics and consumer groups * Concrete design patterns for handling slow and spiky consumers * Migration tips for evolving existing Kafka-based services to use queues safely If you’ve ever stared at a lag graph wondering whether to add more consumers, more partitions, or more coffee, this session will show you a cleaner path to smooth sailing with Kafka. **Bio:** Stephen Ermann is a **Senior Customer Success Technical Architect at Confluent**, working with leading financial institutions across APAC to design and operate mission-critical, real-time data platforms. With deep experience in **Apache Kafka**, **Confluent Cloud and Platform**, and surrounding ecosystems like **Kafka Connect** and **Apache Flink**, Stephen helps customers solve hard problems around scalability, reliability, and security in production. They are particularly focused on **RBAC, OAuth, mTLS, and container image security**, as well as emerging **agentic AI** patterns built on streaming data. Outside day-to-day architecture work, Stephen regularly shares practical patterns and lessons learned at meetups and user groups across the region. \*\*\* If you would like to speak or host our next event please let us know! community@[confluent.io](http://confluent.io/)

Hi Gophers! Join us this April for an evening of Go talks exploring real-world systems, from building a BitTorrent client to running Go on legacy architectures. We are looking forward to connecting with you. * **Agenda** **6:00pm — Food & Networking** **6:30pm — Intro + Go News** **6:45pm — Talks** **8.00pm — Wrap up then head out for kick ons** **🎤 Tom Clancy** **Building a BitTorrent client in Go** BitTorrent, first released in 2001 is a peer-to-peer protocol for file sharing. Its decentralised approach, where pieces of files are exchanged with peers (rather than a central server), is a natural fit for Go's concurrency model. This talk looks at the inner workings of the protocol, how to build your own client, and concurrency patterns for performance. Bio: Tom is a Software Engineer at Megaport, working on their edge networking functions platform (written in Go). **🎤 Sam Hobson** **Compiling Go for Ancient Architectures** Some customers approached Knocknoc asking if we can get our Go agent to run on their old HPUX PA-RISC and Solaris SPARC machines, both unsupported by Go, and we took on the challenge of finding a way to make it work Bio: "I'm Sam, I'm a software engineer of a couple of years working at a startup called Knocknoc on Just-in-time network layer access control software. Please come talk to me about cool stuff you're working on!" * **Interested in speaking at an upcoming event?** We will aim to have a mix of short (\~10min) and in-depth (20-30min) talks. If you’re keen to give a talk on a topic, share a project, or idea, please let us know [bit.ly/GolangMelbourneSpeakersForm](https://bit.ly/GolangMelbourneSpeakersForm)

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.
