Hi Thank you for reading my post I know that i can use a pub/sub model to send a message to several subscriber , and a point-to-point to send message to a queue and then a client will fetch the message .
now i need to have :
Messages should stay in the queue until a clinet come and fetch them , even if it tale several days.
how i should configure the queue for this kind on requirement ? how i should make sure that message will not lose on a server failure ?
