队列触发的Azure Webjob的时间限制

Question

azure Web作业中的队列触发功能是否有时间限制？ 我的函数大约需要20-30分钟，因为它需要遍历数据库中的许多记录。 最后的功能状态为“永不结束”。 我将{。“ stopping_wait_time”：1800}放入settings.job文件-没有任何效果。 但是在五分钟左右的时间内，其状态将设置为“永不结束”。 我搜索了，是的，发现有人问类似的问题-没有明确的答案。 我在日志中发现了一些异常，这些异常似乎是从Azure存储生成的。 我搜索发现日志记录存在一些问题，因此我注释掉了函数中的日志记录代码-仍然行不通。 我也发现了一个提到一些连接字符串的问题-现在我有了这些。 AzureWebJobsStorage，AzureWebJobsDashboard，AzureJobsRuntime，AzureJobsData-都指向同一个存储帐户-仍然无法使用。

我尝试进行调试，看看超时发生在哪里，甚至在我的函数真正被执行之前，它似乎正在发生，

输出如下所示；

System.TimeoutException：客户端无法在指定的超时时间内完成操作。

我为此使用了一个S1 Web应用程序和一个标准GRS存储帐户。

问题是；
1.队列触发功能花费的时间是否有时间限制？
2.如果有时间限制，有什么方法可以克服这些限制？
3.我必须使用队列触发的函数，因为我需要将一些参数传递给该函数-这些参数是从另一个计划的Web作业传递的。 我可以按需制作Webjob并在命令行上传递参数-但是有没有办法从计划的webjob调用按需Webjob？

谢谢你的帮助！

队列触发的作业功能的执行时间没有限制。 但是，您需要确保设置正确，以便JobHost继续运行。 使用Azure WebJobs SDK时，需要将JobHost Console exe部署为连续运行的WebJob ，并启用Always On 。 在本文档页面的“创建连续运行的WebJob”部分下对此都有详细说明。

有关在免费层中运行的超时限制（20分钟超时）的相关详细信息，请参阅该页面的“注释”部分，可以通过移至基本或标准层来删除超时限制。
