Requests are not properly answered

[louiskirsch]

Requests are kept as pending and make http library return http code -1

How to reproduce:

• Use https://github.com/KDD-OpenSource/fexum-frontend/tree/feature/experiment-upstream
• set a target
• click on a few features
• refresh pretty soon afterwards
• Look into Chrome Network tab

Possible problem:
Maybe the celery queue blocks requests being answered?

[nikriek]

We should have some kind of real time queue

[louiskirsch]

Do you know the reason why it blocks entire requests?

[nikriek]

Yes, because it's a one queue. if other tasks are still running, the "real-time" calc has to wait. The solution would be to create another queue

[louiskirsch]

I think we shouldn't put blocking requests into queues at all.
If we do, we need some kind of guarantee that the item is quickly dealt with.

[louiskirsch]

Sooo... how do we deal with this? @nikriek @juliuskunze @Lichtso @marcuspappik @xasetl

Still an issue?
