zhongjiajie opened a new issue #6658: URL: https://github.com/apache/dolphinscheduler/issues/6658
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar issues. ### What happened When I define workflow by code using python, it failed with not exists task. My code definitions as below: ```py from pydolphinscheduler.core.process_definition import ProcessDefinition from pydolphinscheduler.tasks.shell import Shell # make sure your tenant exists tenant = "zhongjiajie" num_workflows = 100 num_tasks = 10 # Whether task should dependent or not, if True would create dependent like `pre-task -> task -> next-task` is_chain = True for wf in range(0, num_workflows): with ProcessDefinition(name=f"wf:{wf}", tenant=tenant) as pd: for t in range(0, num_tasks): task = Shell(name=f"task:{t}-wf:{wf}", command=f"echo task {t}") if is_chain and t > 0: pre_task_name = f"task:{t-1}-wf:{wf}" pd.get_one_task_by_name(pre_task_name) >> task pd.submit() ``` It would sometime failed with error ```log ValueError: Can not find task with name task:1-wf:0 ``` or something like that. I debug and find it due to https://github.com/apache/dolphinscheduler/blob/dev/dolphinscheduler-python/src/main/java/org/apache/dolphinscheduler/server/PythonGatewayServer.java#L132-L135. Python code run so fast, then we get same `code` and in https://github.com/apache/dolphinscheduler/blob/daca3baf6662b9bcf3de856722ece79aad753773/dolphinscheduler-python/pydolphinscheduler/src/pydolphinscheduler/core/task.py?_pjax=%23js-repo-pjax-container#L149-L150 task do not add to workflow ### What you expected to happen Should not get error ### How to reproduce run what I paste above ### Anything else _No response_ ### Are you willing to submit 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.
