Variable Sections Overview

default

This section defines default values for common properties such as the Flink version and the Kubernetes service account. These default values are applicable across all Flink deployments, with the flexibility to override them based on your custom requirements.

sessionMode

Defines the properties for Session Mode Flink setup. Only one instance of Flink can be deployed in this mode. This setup does not include job definitions—it's focused solely on the server part.

sessionJobs

This section depends on the Session Mode configuration. It can be expanded to leverage external Flink clusters without needing to deploy a separate cluster for each job.

applicationMode

Recommended for production environments, the applicationMode section is designed as a list of jobs, each with its independent configuration. This mode offers a more scalable approach for managing multiple Flink jobs within the same deployment.
