Gary Brown commented on RTGOV-393:
----------------------------------

The reason for the change was due to some dependency issues with the new api, which may have been resolved now.

Wanted to get your thoughts on the benefit of cloud vs stream mode, and whether it is beneficial for the user to be able to select between them - or is it better to just use stream?

My main problem with supporting any correlation of events within a drools cep session is that they are not clustered - so if events are handled by different servers in a cluster, then the rule will fail.

> When attempting to using sliding window rules, see[1]. Results in a runtime exception as the DroolsEventprocessor does not support a Stream of events. 
> Recommend fix is making the DroolsEventprocessor configurable from the EPN to use either stream or cloud.
