Creating your first Streams Messaging cluster
You can create a managed and secured Streams Messaging cluster in a CDP Public Cloud
environment by using one of the prescriptive streams messaging cluster definitions and following
these steps.
Meet the prerequisites Before you start creating your first Streams Messaging Data Hub Cluster, you need to ensure that you have set up the environment properly and have all the necessary accesses to use CDP Public Cloud. Use this checklist to make sure that you meet all the requirements before you start creating your first cluster.Create your cluster Once you have met the prerequisites, you are ready to create your Streams Messaging cluster in CDP Public Cloud using a default cluster definition. For this, you must select the cluster definition that matches your cloud provider for the environment and further choose from the light and heavy duty options available.Configure data directories for clusters with custom disk configurations Data Hub clusters provisioned with the default Streams Messaging cluster definitions that have non-identical volume numbers configured for the Broker and Core_brokers host groups require additional configuration after cluster provisioning. If configuration is not done, the Kafka service deployed on these clusters does not utilize all available volumes. Additionally, scaling the cluster might not be possible.Give users access to your cluster As an EnvironmentAdmin , you need provide the users access to your environment and to the new Streams Messaging cluster by assigning user roles and adding users to Ranger policies.
