Amazon MSK Adds Apache Kafka 4.1 with Queues Preview
📣 Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports Apache Kafka 4.1, introducing Queues as a preview feature, a new Streams Rebalance Protocol in early access, and Eligible Leader Replicas (ELR) enabled by default. These features target improved parallelism, optimized Kafka Streams task rebalancing, and stronger availability. To adopt 4.1, select 4.1.x when creating a cluster or perform an in-place rolling update; MSK orchestrates broker restarts to maintain availability. Kafka 4.1 support is available today across all AWS regions where MSK is offered.
