如何仅使用5分钟的窥视锁定即可处理发布到服务总线的长期运行的作业

Question

What do people tend to do when they have a design that put jobs on a service queue or topic that takes longer then the 5min max of peeklock?

I have been using the OnMessage(...) async messagepump of service bus and is wondering if thats not such a good idea after also since if I start moving the jobs to a table while processing them, then the messagepump will just empty the queue and I just have the problem elsewhere of making sure my jobs are scheduled even between servers.

If you have a long running message processing workflow the you can check the lockedUntilUtc property of the message and call RenewLock at the appropriate time.

in the next release of SDK the OnMessage processing loop will automatically do that for you so that convenience API is always a good idea to use.
