I managed to encounter several times a scenario in which an application needed to execute several queries independent of each other, and then group them together somehow. However, each of these queries takes a while to execute. One might wonder: If only we could use some kind of multi-threading mechanism to execute them in parallel, and then the total running time will be that of the slowest query only and not the total of them. Well, it just so happens that our first sample will show how you can implement “multi-threading” in SQL Server using Service Broker queues!
