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)

Namaste, healer. It's time to light up the fifth chakra. It's our energetic voice box — the place where authentic expression, clear communication, and truth all come together. And when it's humming, life just flows better. Hence, our Reiki Throat Chakra Healing Night. Come along and we'll do powerful meditations and group healing to strengthen it. Among other things, the throat chakra is essential for: * Authentic self-expression (so you can speak your truth and be genuinely heard) * Clear communication (so you can express yourself with confidence and ease) * Healthy boundaries (so you can say yes and no from a place of inner alignment) * Creative expression (so your unique voice — in words, art, or any medium — can flow freely) * Living in integrity (so your outer words match your inner truth) So come and join us for a powerful practice night and leave feeling energetically open and authentically expressed. This session will be taken by Reiki master Greg Riddell. Hope you can make it, Jeremy

Your ability to work and live with others is crucial to your survival. To survive well one needs ability. Today meetup topic: Creating and Improving Ability And if you think you already have all the ability one needs to survive well then it is important for you to learn how to KEEP IT FROM GOING AWAY. Attend our Free Meetup! Definition for Ability: One's power to observe, to make decisions and to act. A man is as free, as well-off, as he is able. A family is as happy as it has ability. A business is as well-off as it has able people in it. A country is as well-off as it has able workers, foremen and executives. At today's meetup learn what constitutes ability and more importantly how to develop and improve it so that it does not go away. Fact's are that one's ability is never the same. It either goes up or it will go down. Your natural as well as learned abilities are constantly subject to many of life's pressures. One can therefore simply not rest on one's laurels regarding your current abilities and simply assume they will always be available for use. The time to protect and enhance ability is when you are still able. Any loss of ability will result in less confidence followed by problems resulting in unhappiness. This is called the dwindling spiral. Not just for you, it will impact all others you associate with as well. Today's topic applies to all aspects of life but will focus on how your abilities or lack of abilities or a sudden or gradual lowering of ability relates to work and family life. On your arrival you will be asked to complete a Oxford Personality Test. From this you will learn what ability it is that needs attention and improving. Whilst at our meetup you will also learn about some of the different technologies are that you find here which actively create, protect or enhance ability in key areas of life. The world cries out for better people (More Able People) that will lead happier life's with better better jobs, stronger families as well as community and businesses groups. Get The Know-How for life, attend our meetup or ask me for a time that is better suited to your schedule.

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.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!

We're bringing the community together for a casual happy hour with ServiceNow-themed trivia, food and drinks, and great conversation. Details coming soon - for now, save the date and plan to join us for connection and fun.

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
