Kafka Cluster

Create a Kafka cluster for real-time streaming data pipelines and apps

Apache Kafka is a distributed streaming platform that enables the development of real-time, event-driven applications. It is commonly used to build streaming data pipelines and streaming applications that process and move data between systems in real time. Kafka allows applications to consume and process streams of data at high speed and with high accuracy.

Refer to the AWS documentation for detailed information on using Apache Kafka within the AWS ecosystem.

When creating a Kafka cluster in DuploCloud, if you want to choose a specific cluster configuration or configuration revision, you must first create or define that configuration/revision in the AWS Console before you can select it in DuploCloud.
