The result is a configuration that is tested and supported by Microsoft.Microsoft provides a 99.9% Service Level Agreement (SLA) on Kafka uptime. Here is a description of a few of the popular use cases for Apache Kafka™. It builds upon important stream processing concepts such as properly distinguishing between event time and processing time, windowing support, and simple yet efficient management of application state.

Rebalancing partitions allows Kafka to take advantage of the new number of worker nodes.Azure Monitor logs can be used to monitor Kafka on HDInsight. durability guarantees Kafka provides. The following are specific characteristics of Kafka on HDInsight: For an overview of a number of these areas in action, see It combines the simplicity of writing and deploying standard Java and Scala applications on the client side with … Managed Disks can provide up to 16 TB of storage per Kafka broker.
