IIRC, you can’t perform a Selector operation on the messages’ Destination anyhow.
Right, here’s a page from our docs: Using Selectors pretty much every other message metadata though! I’m guessing this is due to old-school JMS behaviour, where if a message was in a queue, it was b/c it was published directly to that queue, and so every message in that queue would have the same Destination and filtering/selecting based on the message Destination wouldn’t make any sense. That’s not quite as true for modern Solace practices where a queue can attract multiple topics via subscriptions.
Anyhow, I agree with Andrew, I think 6 queues would be the way to go. ??
