Talk:
Deep Dive into Kafka's Group Coordinator and the Coordinator Runtime Framework

Abstract:
Kafka's Group Coordinator is the unsung hero behind consumer group rebalancing, offset tracking, and now, evolving features like shared consumption models. But how does it all work under the hood?

In this talk, we’ll explore the internals of the Group Coordinator in Apache Kafka, with a strong emphasis on the Coordinator Runtime framework—a new abstraction introduced to unify and modularize coordinator implementations within brokers.
We’ll walk through:

• The lifecycle of a consumer group,
• How the Group Coordinator handles membership, heartbeats, and rebalances,
• The architecture of the CoordinatorRuntime and CoordinatorPartition classes,
• How metadata like group state and offsets is persisted in internal topics such as `__consumer_offsets`,
• And how these components ensure durability and fault tolerance at scale.

This session is ideal for engineers looking to deepen their understanding of Kafka internals, especially those interested in the mechanics of consumer group management and metadata persistence. Whether you’re running Kafka in production or contributing to its ecosystem, this talk will illuminate the critical coordinator paths that keep your clients connected and your data consistent.
