Hi,
1. I have a basic question about transactions in AMQP. What exactly does a transaction include/mean? For example, does it include the administrative features like creation of queues, exchanges, etc that will be auto-deleted if the client aborts the transaction. I'm not entirely clear about this, so I'm just trying to understand and figure out possibilities. The spec says that messages and acknowledgments are covered in a transaction. What would happen if the publisher sends a message to the broker/queue, consumer receives (reads it from the queue) and processes it, sends an ack to the broker and then the publisher decides to abort the transaction? How can this transaction be atomic and/or rolled-back since the message is already gone? Please help me understand this. I'm trying to understand the scope of a transaction. 2. Is the protocol currently assuming a reliable transport layer (TCP, SCTP, etc) and no unreliable connection (say, UDP)? If yes, will the later releases work on including unreliable transport layer protocols? Thanks, Tanmay
