问题描述
如果我有一个每隔5分钟运行一次计时器触发器的Azure函数，如果一次运行花费5分钟以上会发生什么?
If i have an Azure Function which runs on a timer trigger every 5 minutes, what happens if one run takes more than 5 minutes?
无论当前正在执行任何触发器，下一个计时器触发器都将启动吗?
Will the next timer trigger kick off, regardless of any currently executing triggers?
原因，我问:我需要确保一次仅运行1个Azure Function(是的，我知道这种做法违背了功能的概念).如果一次运行< 5分钟(大多数情况下应该如此)，太好了-在接下来的5分钟窗口内开始下一个.如果没有完成，请不要开始.
Reason i ask: I need to ensure only 1 Azure Function is running at a time (yes, i know this kind of goes against the concept of functions). If one run takes < 5 minutes (most of the time it should), great - kick off next one at the next 5 minute window. If it doesn't finish, don't kick off.
我更喜欢使用Azure函数，但是在这种情况下-我应该不打扰，而只是使用连续运行的Azure WebJob吗?
I'd prefer to use Azure Functions, but in this case - should i just not bother and simply use a continuously running Azure WebJob instead?
谢谢！
推荐答案
如TimerTrigger 维基页面:
As described in the TimerTrigger wiki page:
因此，您应该已经在寻找所需的行为-在任何给定时间仅运行一个函数调用.
So you should be getting the behavior you're looking for already - only a single function invocation running at any given time.
