英文:
Azure data factory - Concurrence problem in the child pipeline
问题
我有一个父管道和子管道。父管道在foreach活动中触发子管道。数组中总共有6个项目，所以foreach触发子管道6次。我通过取消勾选顺序复选框来使foreach触发子管道并行。我还为子管道提供了6个并发。目前，6个子管道的实例同时运行并在同一时间结束。我希望子管道并行运行，但希望每个实例延迟30或40秒开始，或以30-40秒的差异结束。我有一个下一个活动来检查标志。
我在子管道的末尾添加了延迟，但等待时间确切地在6个实例的同一时间结束。我还尝试添加设置计数器并增加计数器，但由于管道的两个实例在同一时间结束，计数器两次初始化为相同的值。
英文:
i have a parent and child pipelines. Parent pipeline triggers the child pipeline inside the foreach activity. I have totally 6 items in the array so foreach triggers the child pipeline 6 times. I made foreach to trigger child pipeline parallel by unchecking the sequential check box. I have also have given 6 concurrence to the child pipeline. Currently 6 instances of the child pipeline is running at the same and ends at the same time. I want the child pipeline run parallel but i want start each instance by 30 or 40 secs delay or end by 30-40 secs difference. I have next activity which check the flag.
I added the delay at the end of the child pipeline but the wait exactly ends on the same time for 6 instances. I also tried adding set counter and increase the counter but two times counters are intialized with the same value as the 2 instances of the pipeline ends at the same time.

你可以使用 rand 函数来生成指定范围内的随机数，并将该数字用于等待活动中，以便在子流程的执行中创建间隔。
英文:
You many use rand function to generate random number in between range and use that number in wait activity so that you will have gap in execution of child pipelines.
