我创建一个hangfire作业为`BackgroundJob.Enqueue(x => x.Recalculate(itemID));排队工作。当我尝试连续几次保存时,我收到来自Hangfire的错误。
这是堆栈跟踪,

异常消息:后台作业创建失败。有关详细信息,请参阅内部异常。(BackgroundJobClientException)
内部Ex:执行超时已过期。操作完成之前经过的超时时间或服务器没有响应。
有没有人遇到过这个问题?这在本地工作正常。但是在Azure部署中会出现问题。我正在使用v12数据库。感谢任何帮助。我注意到我的所有hangfire作业创建平均需要20秒来排队后台作业。当我试图一次又一次地创造工作时,它会超时。超时似乎是30秒。
我试图增加连接超时但是我在连接字符串中放置了什么值,它似乎在30秒后超时。但是,增加时间无论如何都无法解决潜在的问题。
答案 0 :(得分:0)
我发现大多数时候DTU的使用率都是100%,这是不可接受的,因为测试环境中没有发生任何事情我正在测试它。然后我查看了Azure数据库中的性能数据,这给我提供了性能最差的查询,这非常方便。 Handfire删除作业查询导致此性能问题。这是我们使用的Hangfire版本的一个问题。解决方案是将Hangfire升级到最新版本。
