We have cases where multiple, different subscriptions will match the same message. We would like to avoid multiple deliveries to the same client in cases like this. I've seen the options which allow you to specify a single delivery for multiple, identical subscriptions, but don't see anything for multiple, different subscriptions. Is there any configuration option that lets me do this?
A complicating factor is that we still need to know all of the subscriptions a message matched, even though we would prefer it was only delivered once. On the assumption that there isn't already a way to do this, my follow-up question is: How crazy is it for me to try to make this change? I was looking at TopicHandler.invokeCallbackAndHandleFailure() and wondering if I could replace the call to getSubscriptionInfoArr() with a routine to weed out multiple subscriptions to the same client. I would also have to monkey with the wrapper created in invokeCallback() so that the information about the multiple subscriptions is built into the message before going into the message queue. I shouldn't try this, right? Thanks, John Horner Open Roads Consulting (757) 546-3401 www.openroadsconsulting.com
