Cancel queue job and clear the queue. Also disable job

[niemyjski]

If you want to clear the queue you could call DeleteQueueAsync() but make sure you check the underlying implementation as it may completely delete the queue + configuration. We do this for our unit tests. Also you could always add a setting to your queue job and then look at that setting in dequeue to auto complete a queue entry.

The question was - how to cancel an already running job (queue entry). So, usually, I would use CancellationTokenSource, create a CancellationToken, link it with others if necessary and then, I'm able to monitor this token and stop the job if cancellation were requested.

[niemyjski]

I think what you are doing is the recommended way. @ejsmith, it might be nice to trigger the cancellation token we pass through to get cancelled from the passed in context?

[ejsmith]

Yeah, not sure exactly. When you call dequeue it takes a cancellationtoken that can be cancelled to stop the processing as long as you are checking in your long running code for it to be cancelled periodically.

[paulreicherdt]

Yes, sure, I need to check the cancellation token periodically. I do it. And using cancellation token I'm able to cancel my job on any place. Or even within .net library code.
I have seen, that there is a cancellation token within job context. So, it may be a nice solution - to cancel all queued jobs by cancelling from the queue.

Also, the possibility to disable a job would be nice. By e.g. instance count set to 0.
