speed of queue browsing to see if an item is already enqueued…
I have the need to check if a given item, with a specific key, is already
in the queue, or scheduled for future execution.
What’s the performance of this like? Is it relativity efficient? My
requirements for this aren’t very high… I may be doing maybe 1-5% of my
load with this type of query.

ok.. that’s reasonable. Thanks for the reply.. I think what I’ll do is
have some basic sanity assertions run periodically.

It will depend on the queue depth b/c it is a linear search to find a
match. But all messages will be in memory so it will be quick.
