### 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 **I think we should check to see if there are identical events that are unique in the queue before adding events. In some cases, repeating a completed event may raise an exception** **WorkflowExecuteRunnable.java**  **In addition, I think we should use poll() instead of peek() for fetch events, and add exception events to the end of the queue if they need to be processed repeatedly, otherwise they will always block processing of other events in the queue** **WorkflowExecuteRunnable.java**  ### 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.
