Title: EFFICIENTLY RECEIVING MESSAGES ACROSS A LARGE NUMBER OF MESSAGING ENTITIES
Abstract:
A messaging service is described that facilitates the efficient receipt of messages by a client from across a large number of messaging entities hosted by different messaging hosts within a distributed messaging system. A gateway in the distributed messaging system forwards a request for an available message or set of related messages from the client to each of the messaging hosts. Each messaging host provides a response to a request if a messaging entity hosted thereby includes at least one available message or set of related messages. The messaging host manages the order in which responses from different messaging entities are provided to ensure fairness. The gateway forwards a selected one of the responses to the consumer, while caching the other responses to service future requests from the consumer.
