List unique Property value is also used by my colleague for his case.
He has about 1000 users but is only allowed to create about 10 thread of messages consumer
to serve them due to resource available.
When a user logs in, the system should check whether there is a message for them or not.
if there is, than the messages will be consumed and forwarded to the user.
When the number of user is more than the number of thread available, users will be served
one after another using a scheduler algorithm (round robin, FIFO, etc).
His plan was using message consumer with message selector, but he needed to change the
selector often. With list unique property, he can see directly which user has messages and
change messages selector efficiently.
