Hi all again, my apologies for all these questions.
I am trying to clarify my understanding around transactions support within qpid and here is my current understanding (based on documentation & JIRA). I have to say I did not test anything yet. My use cases all go into the same pattern : (1) writes into a DB & publishes messages or (2) consumes messages and updates a DB, all of this being "atomic" (e.g. if the DB writings fail, messages are not sent etc...), with Java & C++ clients and I am figuring out if I can rely on XA / DTX or if I need to find another implementation. Here is my current understanding, any comments are welcomed.

Can you help ? Cheers. oliv/
