The new service description is similar to old broker publish, Message provider can be found in the IS messageing configuration or specified in the publishable document. There are some new exceptions documented in the new description, which were not in old publish and have to be handled in the interface.
Publish and Wait is not supported. Usual triggers will work.
Regarding the performance issues - hope it shouldn’t be a problem, given the performance of UM with guaranteed delivery is supposed to be better than broker. And yes, there will be some performance difference between (two/three different versions of UM??)
- Full feature version (pay more) with very low latency
- Broker equivalent with increased latency, still better than Broker. This does nots upport active-active clustering and other extended features of UM
- Broker Equivalent with active-active clustering enabled?? - No idea on this.
