Over the last few years, we have been working on removing the dependency on ZooKeeper from Apache Kafka®. Instead of using an external system to store metadata, Kafka can now manage its own metadata. This new mode of operation is called Kafka Raft mode, or ""KRaft"" for short. It has many performance and scalability benefits.
This talk will discuss our efforts to get KRaft mode production-ready. We will talk about the old and new architectures, and how we adapted features to work in both worlds. We will also talk about our experiences with testing and deploying the new software. Finally, we'll talk about what's planned for the future.
