[Feature][Server] Let dependent nodes wait for a while before the pre-process starts #3633
Description
description
The dependent node is used when the dependent task is executed periodically. In the original design, if the dependent node starts execution first, but the process instance of a task does not exist, the dependent node will be directly judged as a failure. Now, with the addition of new features, dependent nodes can choose to wait for a period of time before starting execution.
To realize the idea, this feature adds a new timeout data structure, which mainly contains two attribute members: timeout and check interval. When the dependent node is running, if this function is turned on, it will check whether the pre-process instances have started at regular intervals according to the check interval. If all pre-process instances have started within the timeout period, then run directly. Otherwise, the timeout fails.
