Yes. In general, I don't like comparisons between RDBMSs and messaging, but I think here there are some parallels. Most RDBMSs don't have transactional DDL and it is the same with AMQP (the edge cases tend to be quite troublesome). Also any design involving a lot of DDL at runtime doesn't feel quite right when using an RDBMS. It would be useful I think if you could outline what you are trying to achieve - I think there are almost certainly other ways of designing the solution. For example, have you considered using message selectors? Thanks, Robert
