Quick Purchase of a Kafka Streaming Cluster

Updated at: Oct 21, 2021 GMT+08:00

This section describes how to quickly purchase a Kafka streaming cluster. The Kafka cluster uses the Kafka and Storm components to provide an open-source messaging system with high throughput and scalability. It is widely used in scenarios such as log collection and monitoring data aggregation to implement efficient streaming data collection and real-time data processing and storage.

The Kafka streaming cluster consists of the following components:

  • MRS 1.9.2: Kafka 1.1.0, Storm 1.2.1, and Ranger 1.0.1
  • MRS 3.1.0: Kafka 2.11-2.4.0, ZooKeeper 3.5.6, and Ranger 2.0.0
