  • DURABLE EXACTLY ONCE MESSAGE DELIVERY AT SCALE
    Publication number: 20090133039
    Abstract: The present invention extends to methods, systems, and computer program products for durable exactly once message delivery at scale. A message capture system uses a synchronous capture channel and transactions to provide durable exactly once message capture. Messages are sent from the message capture system to a message delivery system over a network using an at least once transfer protocol. The message delivery system implements a durable at most once messaging behavior, the combination of which results in durable exactly once transfer of messages from the message capture system to the message delivery system. The message delivery system uses a synchronous delivery channel and transactions to provide durable exactly once message delivery. Cursors maintaining message consumer state are collocated with message consumers, freeing up message log resources to process increased volumes of messages, such as, for example, in a queued or pub/sub environment.

  • Queued sessions for communicating correlated messages over a network
    Patent number: 7421501
    Abstract: Systems and methods in accordance with the present invention allow for messages to be delivered from one application to another over a network in discrete groupings or communication sessions. For example, a sending computer system sends a group of related messages to a queue at a recipient computer system. The recipient computer system identifies that the messages of the group are related, and initiates a session-oriented communication channel. The recipient computer passes the group of messages to an appropriate application, and opens a different, new session-oriented communication channel for a new group of messages that are not necessarily related to the first group of messages. In one implementation, an order identifier in each of the received messages instructs the recipient computer system on what order, if any, the messages in a group are to be processed by the specific application.
