Abstract
An approach for a publisher-assisted, broker-based cache that can be utilized to reduce a volume of data delivered between a publisher and broker is provided. Specifically, when a message is being generated on a publisher system, the publisher system will determine if the message includes a set of data that has a potential to be repeated in subsequent messages. An identified set of data will be associated/marked/tagged with a unique identifier corresponding thereto. The modified message will be sent to a broker system, which will detect/locate the unique identifier, cache the corresponding data, and send the message along to any applicable subscriber systems. When a subsequent message that is supposed to contain the cached set of data is generated, the publisher system will substitute the unique identifier for the set of data to yield an abbreviated message and send the abbreviated message to the broker system.
