Tasks

A Speedwagon job contains one or more tasks that do some kind of work.

To perform work as part of a job, the Workflow needs to take input provided by the user and turn it into tasks. This is done in two steps. First with discover_task_metadata() method and then with the create_new_task() method.

The discover_task_metadata() method is for generating a list of serializable metadata that could be used to generate a task.

The create_new_task() method uses the information generate by discover_task_metadata() to generate tasks.

The initial_task() method is simular to create_new_task() but the execution of these tasks after the job is submitted but before get_additional_info() and discover_task_metadata() methods. It is useful for gathering information about potential tasks will be run. For example: This could run a task that is traversing a path with many items.
