> After the worker-server is down, should the backlog of task instances be run or not? If run it, it will cause excessive pressure on the worker-server, as you said. If it is not run, a large number of task statuses will be abnormal. But when running, you can reduce server pressure by configuring the number of concurrent threads in worker-server's exec-threads (default 100). worker should be executed, but the scene is a different case. I created a process, and only one task is created in this process. Normally, only one process_instance and a corresponding task_instance are generated. But now the situation is that a process_instance and multiple task_instances are generated, and before the worker is not restored, the task will be generated every 1 second. -- This is an automated message from the Apache Git Service.
