Abstract
The present invention extends to methods, systems, and computer program products for maintaining message state at a message log. Messages are accumulated at a message log in accordance with a message retention policy. Any of a variety of message capture assurances can be used when capturing a message from a message producer within a message log. A message becomes visible to message consumers after the outcome of writing the message is known (either failure or success). Messages are requested using (e.g., monotonically increasing) sequence numbers. Messages are also dropped from the message log in accordance with the message retention policy.
