📋 Agenda

🎉 18:30 Introductions & snacking time
Kick off the evening with a warm welcome, even warmer 🍕 pizzas and some 🍺 cold drinks!

🎙️ 19:00 Talks
💣 Rate my Pizza: Cooking custom metrics and traces with OpenTelemetry

Talk Description: OpenTelemetry auto-instrumentation is a great start for observability, but the default metrics and traces don't always answer the real questions. In this interactive session, we'll explore custom instrumentation through a live pizza rating application, with audience data visualised in Grafana.
We'll look at metric types like Gauge, Counter and Histogram, and learn how to enrich traces with the context that really matters.
By the end of the session, we'll settle the ultimate question: what pizza does the audience prefer?

Speakers: Enis Spahi, Architect Consultant at OpenValue

💣 Breaking Kubernetes for fun and profit

Talk Description: Kubernetes is complex, powerful… and surprisingly easy to mess up. In this talk, we’ll take a guided tour through the dark alleys of Kubernetes misconfigurations, privilege escalations, and real-world attack vectors. You’ll see live demos of how attackers exploit innocent-looking setups — and more importantly, how you can detect, prevent, and recover from them.

Speakers: Ali Alp, Distinguished Software Architect @ Brainlab

💣 Grafana Drilldown – queryless satisfaction

In this talk Basti will cover the drilldown features that help you navigating your metrics, logs, traces and profiles without learning to write queries.

* Metrics Drilldown is the way of browsing Prometheus-compatible Datasources without the need of writing PromQL
* Logs Drilldown lets you automatically visualize and explore your Loki Logs
* Traces Drilldown helps fetching insights from Tempo traces data
* Profiles Drilldown assists you in exploring your profile data that is stored in Pyroscope

Learn some tricks that help you managing your observability data faster and more efficient.

Speakers: Basti Schubert, Solutions Engineer @ Grafana Labs

The event is well-suited for DevOps and Site-Reliability engineers, and we welcome people who are new to Grafana or observability. We look forward to seeing you all there!

Get ready for an unforgettable pre-Durga Puja celebration where technology meets tradition! This **CNCF Mega Meetup x Grafana Kolkata** is not just another tech gathering — it’s a high-energy fusion of **cutting-edge cloud-native innovations** and the festive spirit of the season.

We’re bringing together **developers, architects, DevOps engineers, open-source contributors, and cloud enthusiasts** under one roof to share knowledge, showcase projects, and explore the latest in Kubernetes, container orchestration, microservices, and CNCF technologies.

Expect **inspiring talks from industry leaders, lightning sessions from the community, live demos, and open networking** that can spark your next big collaboration.

And because it’s the season of joy, we’re adding a splash of celebration — think **Puja-themed quiz contests, fun games, swags, stickers, and cool giveaways** for our most engaged participants. You’ll leave not only with fresh ideas for your next deployment but also with **memories of a festive evening well spent with your tech tribe**.

Whether you come to **scale your knowledge, share your expertise, or just soak in the culture and camaraderie**, this is the place to be before the Puja lights take over the city. Let’s celebrate innovation and tradition, side by side.

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.

**HCS Company**: Anthony Fokkerweg 61\, Amsterdam \| [https://maps.app.goo.gl/LPMZKBzB7MutGrZb6](https://maps.app.goo.gl/LPMZKBzB7MutGrZb6)

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! 👋
