Amazon MSK Express brokers now support Intelligent Rebalancing on existing clusters

Amazon MSK Provisioned clusters with Express brokers now support Intelligent Rebalancing across all existing clusters at no additional cost. Previously limited to newly created clusters, Intelligent Rebalancing is now available for all MSK Provisioned clusters running Express brokers, enabling customers to effortlessly benefit from automatic partition balancing when scaling their Express-based clusters up or down. Intelligent Rebalancing maximizes capacity utilization of MSK Express-based clusters by optimally rebalancing Kafka resources for improved performance, eliminating the need for customers to manage partitions themselves or through third-party tools. It performs these operations up to 180 times faster compared to Standard brokers. Clusters are continuously monitored for resource imbalance or overload based on intelligent Amazon MSK defaults to maximize cluster performance. When required, brokers are efficiently scaled without affecting cluster availability for clients producing and consuming data. Intelligent Rebalancing is now available on all MSK Provisioned clusters with Express brokers in all AWS Regions where Express brokers are offered.
