Understanding retry parameters of GCP cloud task queue
问题
GCP云任务文档没有详细解释重试参数。是否有人可以帮助理解重试参数，特别是MAX_INTERVAL、MIN_INTERVAL、MAX_DOUBLINGS和MAX_RETRY_DURATION。
考虑到我有一个HTTP目标，每当分派任务时都会调用它，如何决定这些参数的值应该是多少？
英文:
GCP cloud task document doesn't explain the retry parameters in much depth. Can someone help in understanding the retry parameters specifically MAX_INTERVAL, MIN_INTERVAL, MAX_DOUBLINGS and MAX_RETRY_DURATION.
Considering that I have an http target which gets invoked whenever a task is dispatched, how to decide what should be the values of these parameters?

那些参数是"重试参数"。这意味着它们仅在您的任务失败（或超时）时使用。
当发生错误时，Cloud Task 将等待最少时间，即MIN_INTERVAL。但这个等待时间永远不会超过MAX_INTERVAL。
为什么有MAX_INTERVAL？因为在每次失败时，您可以指定"等待时间"翻倍的次数。这是MAX_DOUBLINGS参数。
而且，因为您不希望永远等待/重试，最大处理持续时间，包括重试，不能超过MAX_RETRY_DURATION。
英文:
Those parameters are the "retry parameters". It means, they are used ONLY when your task fails (or timeout exceeded).
When an error occurs, Cloud Task will wait a minimum of time, the MIN_INTERVAL. But this wait will never exceed the MAX_INTERVAL.
Why a MAX_INTERVAL? Because at each failure, you can specify the number of time that the "wait time" is doubled. It's the MAX_DOUBLINGS parameter.
And because you won't wait/retry eternally, the max processing duration, retries included can't exceed the MAX_RETRY_DURATION
