The Truth About ZooKeeper Removal and the KIP-500 Release in Apache Kafka ft. Jason Gustafson and Colin McCabe

  • Transcript
  • Notes

Jason Gustafson and Colin McCabe, Apache Kafka® developers, discuss the project to remove ZooKeeper—now known as the KRaft (Kafka on Raft) project. A previous episode of Streaming Audio featured both developers on the podcast before the release of Apache Kafka 2.8. Now they’re back to share their progress.

The KRraft code has been merged (and continues to be merged) in phases. Both developers talk about the foundational Kafka Improvement Proposals (KIPs), such as KIP-595: a Raft protocol for Kafka, and KIP-631: the quorum-based Kafka controller. The idea going into this new release was to give users a chance to try out no-ZooKeeper mode for themselves. 

There are a lot of exciting milestones on the way for KRaft. The next release will feature Raft snapshot support, as well as support for running with security authorizers enabled.

Engaging Database Partials with Apache Kafka for Distributed System Consistency ft. Pat Helland

When compiling database reports using a variety of data from different systems, obtaining the right data when you need it in real time can be difficult.

Adopting OpenTelemetry in Confluent and Beyond ft. Xavier Léauté

Collecting internal, operational telemetry from Confluent Cloud services and thousands of clusters is no small feat. Traditionally, this data needs to be collected in multiple ways to satisfy all the different requirements. However, this sometimes leads to discrepancies between various systems. With OpenTelemetry, we can collect data in a vendor-agnostic way. Many vendors already integrate with OpenTelemetry, which gives us the flexibility to try out different observability solutions with minimal effort, without the need to rewrite applications or deploy new agents.
