Confluent Cloud Is Now 100% KRaft and You Should Be Too

The latest development in Apache Kafka's migration to self-managed metadata in KRaft is now production-ready. The new consensus protocol replaces ZooKeeper for metadata management and cluster consensus, allowing for improved scalability, stability, and security. Confluent has successfully migrated thousands of clusters to KRaft without downtime, demonstrating its readiness for production use. With KRaft, Kafka can handle millions of partitions across a fleet of clusters with increased efficiency, reducing complexity and improving overall system stability. The migration process is now available through various tools, including Confluent's CFK and Ansible Playbooks, making it straightforward for experienced operators to transition to KRaft.
