[rules-users] Fusion - Why needs the stream time-ordered input

[Tina Vießmann]

Hi,

I'm restarting getting to know Drools (Fusion). Now I'm thinking about 
the stream processing mode.

The documentation says the events must be time-ordered - they must be 
insert into the stream in the order in which they are occur so. Am I 
correct that it has to be that way, because the timestamps given to the 
events when they are insert into the working memory shall represent the 
correct order?
My events already have an attribute representing their timestamp. I've 
told that the engine using the @timestamp(...) command.
In that case, is it important anyway that the events are insert 
time-ordered?

I'm thankful for any explanations and advises. Thank you :)
