As organizations increasingly rely on Apache Kafka for mission-critical workloads, ensuring high availability across Kubernetes clusters is a key challenge. What if Strimzi could support Kafka deployments that span multiple clusters, improving fault tolerance and resilience?

In this talk, we’ll explore the concept of Stretch Clusters, a proposed enhancement to Strimzi that enables Kafka brokers to be distributed across Kubernetes clusters while maintaining a unified deployment model.

We’ll discuss:

- The motivation behind Stretch Clusters and real world scenarios where they could be beneficial.
- The current prototype and how it leverages Cloud Native Network solutions like Submariner, Cilium.
- The technical challenges, including state consistency, networking, and failover handling.
- Key considerations for the Strimzi community, what it would take to make this a viable feature in Strimzi.

This session is not just about a feature proposal. it’s an opportunity to spark discussion within the community about how Strimzi could evolve to support multi cluster Kafka deployments. Whether you’re a Strimzi contributor, Kafka operator, or cloud-native architect, join us to share your thoughts and help shape the future of Strimzi!
