Spring Cloud Task utilizes a datasource for storing the results of task executions. By default, we provide an in memory instance of H2 to provide a simple method of bootstrapping development. However, in a production environment, you’ll want to configure your own DataSource.

If your application utilizes only a single DataSource and that will serve as both your business schema as well as the task repository, all you need to do is provide any DataSource (via Spring Boot’s configuration conventions is the easiest way). This will be automatically used by Spring Cloud Task for the repository.

If your application utilizes more than one DataSource, you’ll need to configure the task repository with the appropriate DataSource. This customization can be done via an implementation of the TaskConfigurer.
