[rabbitmq-discuss] Support for distributed transactions (dtx).

Pardon me for hijacking this thread, but I have 2 transaction related questions.
1) If I am just sending one message per client invocation, does it
matter whether I use transactions ?
e.g. the server receives a request to create an account, I add that
request to a Q.
It seems to me that transactions are only useful if I want a group of
messages to appear (perhaps in an ordered fashion) in the queue. I'm
speaking from a one-phase commit viewpoint.
2) In one of the overload method signatures for Channel.basicPublish,
2 parameters "immediate" and "mandatory" confuse me. Are they in
anyway related to transactions ? Are they hints to control the
visibility of the message in the queue vis à vis database isolation
Thanks a lot.
