I'm going back and forth as to whether to use a static or dynamic queue for a simple request / reply setup.
What are the +'s and -'s to creating a dynamic queue on the fly and putting a message, then putting a response on that dynamic queue, and getting the response from the queue... as opposed to doing the same thing, but on a statically defined local queue? |

It has to do with the lifetime of the requesting application.
If the requesting application is going to start and stop infrequently and only be running for a small amount of time, it's reasonable to use dynamic queues.
If the requesting application is going to start and stay running for a long time, or is going to start and stop on a frequent basis - or at least open and close it's queue on a frequent basis, then you absolutely always want to use a predefined queue.
You then make the decision on whether or not that predefined queue is shared with other instances of an application based on the volume of messages coming into it. |
