Is it restricted by ignite to put elements into queue in closures

[fatality <fa...@gmail.com>]

Hi 

I have posted below question a while ago and still not received any response
yet. Could you please tell me what can be accessed or can not be from
closures that we send with remotelisteners.

Well, actually the question was answered on stackoverflow
<http://stackoverflow.com/questions/43891757/closures-stuck-in-2-0-when-try-to-add-an-element-into-the-queue>
with the following:

It's not allowed to invoke ignite.queue and ignite.affinity methods in
EventListener, because it may lead to deadlock.

All cache operations, including EventListeners are executed in system pool,
so it's not recommended to invoke inside EventListener operations, that
uses system pool too.

You could read more here at "Closures Execution and Thread Pools":
https://apacheignite.readme.io/docs/async-support#section-listeners-and-chaining-futures

And here
https://apacheignite.readme.io/docs/thread-pools#section-system-pool



Kind regards,
Alex.
