Sebastian Łaskawiec commented on JGRP-2224:
-------------------------------------------

Ok looks good to me.

Could you please explain how it works in details? I'm especially interested in:
* What is the order of invoked discovery protocols? Is {{FILE_PING}} invoked before {{MPING}} in your example or it's the other way around?
* What happens if all discovery protocols return different results? Can I merge them somehow?

> Allow for multiple discovery protocols. This would allow us to use a single configuration which includes discovery protocols for multiple cloud providers.
> The discovery protocols could be queried sequentially (return on result), or in parallel.
> Investigate whether we need a super discovery protocol which instantiates the individual protocols, or whether each protocol should be changed e.g. to forward events down the stack.
