Event Queues - Comments on Pros & Cons?

[Rankin, Andrew AJ]

Hi all,
 
>From what I have read, event queues are available to assist with performance where there is a likelihood of a large number of the same event being created in a very short space of time. To date, I haven't used them and haven't had problems, and I don't expect that to change. However the other thing that also interests me is that you can use the event queue to manage the case where event linkages end in an error, so that with the correct settings in the event linkage, if necessary these events can be resubmitted once the problem is fixed.
 
We had the situation a while ago where a small number of event linkage instances went into error because a table space was filled. Fortunately it was picked up early, and I only had to recreate a small number of these events by hand. If the number was large, I don't know how I would manage to kick off all the worklfows required without spending many tedious hours doing it manually. Perhaps this was a freak occurrence, but it makes me think that I should switch on the event queue for everything, to cover this risk in the future. So what is the downside to using the event queue, if any?
 
The other thing I'm wondering though is if I do switch it on, will it see event linkages that end with exception due to a start condition killing it (which we want to happen)? What else do I need to consider?
 
I thank you for any expert advice.
 
Andrew Rankin.
