**Metrics Drilldown**
Grafana’s queryless solution that helps users explore massive amounts of observability data without writing complex queries. Sound familiar? As metrics become easier to collect, organizations face an even greater challenge: uncovering meaningful insights in ever-growing volumes of data.

In this talk, you’ll learn how Metrics Drilldown addresses that challenge with powerful new features for slicing, dicing, sorting, and correlating your metrics. We’ll showcase these capabilities in a live demo using OpenTelemetry data sources and show how this unified approach eliminates the usual back-and-forth between tools during troubleshooting. The result is a data exploration experience that is accessible to everyone on your team, regardless of their technical background.

**eBPF/Beyla**
Observability is essential, but adding it shouldn't mean rewriting your entire application. In this talk, we'll explore how Beyla, an open-source auto-instrumentation tool built by the Grafana Labs team and recently donated to the OpenTelemery Project leverages eBPF to provide zero-code, low-overhead observability for your services.

Whether you're working with Go, Java, or other languages, Beyla enables you to trace HTTP/gRPC traffic and export OpenTelemetry-compatible data all without touching your codebase. We'll dive into how Beyla works under the hood, what use cases it's best suited for, and how to get it running in minutes.

Expect a live demo, lessons learned from real-world adoption, and a practical look at how Beyla fits into modern Linux-based observability stacks. If you're ready to "auto-instrument all the things" and reduce friction between developers and observability teams, this session is for you.

We're thrilled to invite you to our next meetup, a joint event with the [Amsterdam Apache Kafka](https://www.meetup.com/amsterdam-apache-kafka-meetup/) community 💥

Many thanks to our great friends at [HCS Company](https://www.hcs-company.com/), who have kindly offered to host us at their Amsterdam office 🫶

📕 **Agenda**

**17:30** Open doors.
**18:00** Food & Drinks
**18:30** Meetup starts

1️⃣ **"Supercharging Grafana with Community Plugins"** by **[Imma Valls](https://www.linkedin.com/in/imma-valls/)**, Staff Developer Advocate at [Grafana Labs](https://grafana.com).
Grafana is powerful on its own, but its true potential lies in its vibrant community of plugin developers. In this talk, we'll dive into how community plugins extend Grafana's core functionality, enabling you to connect to a broader range of data sources and visualize your data in new ways. We'll introduce the **[Kafka Data Source plugin](https://grafana.com/grafana/plugins/hamedkarbasi93-kafka-datasource/)** as a practical example, demonstrating how it lets you directly query and visualize Kafka topic data in your dashboards, bypassing the need for intermediate storage or external services.
2️⃣ **"Which Data Format Should I Use in Apache Kafka?"** by **[Maria Berinde-Tâmpănariu](https://www.linkedin.com/in/maria-berinde-tampanariu/)**, Staff Solutions Engineer at [Confluent](https://www.confluent.io/).
You're just starting your data streaming journey or are extending it to include Schema Registry and you learned that multiple serialization formats are supported. How do you know which one(s) to choose? What if the choice is not yours? If you are offering the data streaming service as a platform to your internal customers, what kind of guidance should you offer them when choosing a data format? Is everything which is possible advisable? What implications does mixing data formats have? How do different formats differ from each other in terms of limitations, evolution and linking options? How does this affect consumers? In this talk I will share questions, answers and tradeoffs as identified while working with customers who were implementing Confluent Schema Registry.
3️⃣ **"Iced Kaf-fee: Chilling Kafka Data into Iceberg Tables"** by **[Danica Fine](https://www.linkedin.com/in/danica-fine/)**, Sr Manager, OSS Developer Relations at [Snowflake](https://www.snowflake.com/).
Have piping-hot, real-time data in Apache Kafka® but want to chill it down into Apache Iceberg™ tables? Let’s see how we can craft the perfect cup of “Iced Kaf-fee” for you and your needs!
We’ll start by grinding through the motivation for moving data from Kafka topics into Iceberg tables, exploring the benefits that doing so has to offer your analytics workflows. From there, we’ll open up the menu of options available to cool down your streams, including Apache Flink®, Apache Spark™, and Kafka Connect. Each brewing method has its own recipe, so we’ll compare their pros and cons, walk through use cases for each, and highlight when you might prefer a strong Spark roast over a smooth Flink blend—or maybe a Connect cold brew. Plus, we’ll share a sneak peek at future innovations percolating in the community to make sinking your Kafka data into Iceberg even easier.
By the end of the session, you’ll have everything you need to whip up the perfect pipeline and serve up your “Iced Kaf-fee” with confidence.

Ya estamos de vuelta tras el verano 🚀, y visitaremos las oficinas de [Kyndryl](https://www.kyndryl.com/es/es) en l'Illa Diagonal de Barcelona 💥

📍**Ubicación:**
c/ Numancia 164\, Barcelona \| [https://maps.app.goo.gl/NiFWVTa7URkSAgey9](https://maps.app.goo.gl/NiFWVTa7URkSAgey9)

**📅 Agenda:**

**18:00:** Bienvenida 👋
**18:30:** 🎙️ **"Detrás de las transacciones bancarias: Un vistazo a la observabilidad con Grafana en Kyndryl"**, [Alberto Cantero](https://www.linkedin.com/in/alberto-cantero-0754029b/) \- Observability Service Manager en Kyndryl \(charla en castellano 🇪🇸\)
¿Qué sucede detrás de un simple retiro de un cajero o una transacción en línea? En esta sesión, te daremos un tour por nuestros dashboards de Grafana y te mostraremos cómo monitorizamos en tiempo real las transacciones, la carga de los servicios y el rendimiento de la red. Una charla perfecta para quienes quieren ver cómo se aplica la observabilidad en escenarios del mundo real. Y cuales son nuestros planes de futuro.
**19:15:** 🎙️ "**What is Memberlist? Using a gossiped KV Store for Grafana Mimir’s HA Tracker**" [Nikos Angelopoulos](https://www.linkedin.com/in/nikos-angelopoulos-9611b018a/) \- Senior Site Reliability Engineer en Grafana Labs \(charla en inglés 🇬🇧\)
Memberlist is a Go library that implements a gossip-based protocol for cluster membership and messaging. It provides a lightweight way for nodes to discover each other, detect failures, and exchange state — all without relying on an external coordination service like etcd or Consul.
In this talk, we’ll explore how Memberlist works under the hood: its gossip protocol, failure detection and message propagation. Then, we’ll look at a real-world use case: Grafana’s HA Tracker. Originally dependent on etcd, the HA Tracker was migrated to a key-value store backed by Memberlist to remove external dependencies and simplify operations.
**20:00 - 21:00:** Networking con pizzas y bebidas 🍻🍕

¡Nos vemos allí! 👋
