in skelta help  was described abut queue but i don't understand end use of it, please describe for  me by using simple sample that when  i can use from queue ?

best regards.

Use of Queue will depend on your business requirement. Say, if you want to allocate an item to an actor based on the no of items allocated to the user or on a round robin basis etc, you can use queue. You can define multiple participants in a queue, it will be allocated to one actor among the participants based on the dispatch pattern you set to the queue.
