Hi @sakuraime ,
The Scheduler is responsible for creating and destroying Workers according to requirements. Workers use Scheduler directly. Each Worker can only be associated with one Scheduler. Workers cannot be transferred from one Scheduler to another.
The unit of work processed by the Worker can be a Request or a Task. For example, batch processing Request may be decomposed into multiple Tasks. When the Scheduler receives a new Request or Task request, if there is no idle Worker (Idle Worker) currently, it will start to create a new Worker according to the configuration, and the Request or Task will be bound to the Worker.
I find a blog explain this, but the blog is in Chinese, please refer to SQL Server scheduler.
