### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Right now, we use `WorkflowExecuteRunnable` to handle the workflow event and task event, this make this class be huge if we need to add a new event, we need to modify this class, it will be hard to add new event. I have an idea, we can split the workflow event and task event into different event queue, and use different event handler to deal with different event, when we handle a target event, we may need to generate new workflow/task event. <img width="1598" alt="image" src="https://user-images.githubusercontent.com/22415594/173989139-6b5f68db-ab59-4330-8368-38fe9958d290.png";> The advantage is that, we can split the event handle logic, and when we need to add a new event type, we only need to add a new event handler. There is some problem need to deal, the task/workflow's events may need to have order, we may still need to create event queue for each workflow, or use state machine to implement the order. This is just an open discussion, welcome to discuss. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
