Client-Controlled Workflow Job.

Provides methods for adding client-controlled swarm learning, cyclic, and cross-site evaluation workflows.

Parameters:

• name (name, optional) – name of the job. Defaults to “fed_job”

• min_clients (int, optional) – the minimum number of clients for the job. Defaults to 1.

• mandatory_clients (List[str], optional) – mandatory clients to run the job. Default None.

• executor_tasks (List[str], optional) – tasks for the executor

• external_resources (str, optional) – External resources directory or filename. Defaults to None.
