Log4j uses a hierarchical model for configuring loggers within an application. KIP-684 allows you to enable mutual TLS on SASL_SSL listeners, improving their ability to secure their environments. Historically, you could only configure this authentication mechanism broker-wide, despite the fact that KIP-103 introduced the ability to independently configure different network listeners on the broker. Kafka brokers support TLS client authentication (also known as mutual TLS authentication) to secure the client-broker system. KIP-684: Support mutual TLS authentication on SASL_SSL listeners This change enables the addition of new admin features in the future without disruption to the producer and consumer.

KIP-700 decouples the AdminClient from the Metadata API by adding a new API to directly query the brokers for information about the cluster. However, the Metadata API is primarily focused on supporting the consumer and producer client, which follow different patterns than the AdminClient. The Kafka AdminClient has historically used the broker’s Metadata API to get information about the cluster. KIP-590: specifies a new protocol to allow forwarding client requests from brokers to the controller.KIP-631: specifies the event-driven controller model, including the new broker lifecycle and the metadata record schemas.KIP-595: specifies the Raft protocol, which is used for the topic.KIP-500: lays out the vision for an event-driven model for managing metadata with a replicated log managed with the Raft protocol.Here is a quick look at the most significant KIPs that have been We expect significant improvements when it comes to feature completeness and hardening by the mid-year and end of year releases. This release has been a massive effort by the community over the past year, and this will continue over the course of this year. See the README for quickstart instructions and additional details. A node in the KIP-500 world can serve as a controller, a broker, or both, depending on the new process.roles configuration. The leader of the Raft quorum serves the same role as the controller in clusters today. We are excited to announce that 2.8 introduces an early-access look at Kafka without ZooKeeper! The implementation is not yet feature complete and should not be used in production, but it is possible to start new clusters without ZooKeeper and go through basic produce and consume use cases.Īt a high level, KIP-500 works by moving topic metadata and configurations out of ZooKeeper and into a new internal topic named This topic is managed by an internal Raft quorum of “controllers” and is replicated to all brokers in the cluster. Kafka broker, producer, and consumer KIP-500: Replace ZooKeeper with a self-managed quorum This highly anticipated architectural improvement enables support for more partitions per cluster, simpler operation, and tighter security. This release offers an early access version of KIP-500, which allows you to run Kafka brokers without Apache ZooKeeper, instead depending on an internal Raft implementation.
