Publisher-assisted, broker-based caching in a publish-subscription environment
First Claim
1. A method for caching potentially repetitive message data in a publish-subscription (pub/sub) messaging environment, comprising:
- identifying, on a publisher system, a set of data in a first message, the set of data scheduled to appear in a number of future messages above a predetermined threshold;
associating the set of data with a unique identifier;
sending the first message to a broker system;
locating the unique identifier in the first message;
storing the set of data associated with the unique identifier in a cache, the cache located in a set of subscriber systems;
generating a second message on the publisher system, the second message having the unique identifier in place of the set of data;
sending the second message to each of a plurality of subscribers through the broker system;
locating, by each of the plurality of subscriber systems, the unique identifier in the second message;
retrieving, by the each of the plurality of subscriber systems, the set of data from the cache; and
replacing, by the each of the plurality of subscriber systems, the unique identifier in the second message with the set of data.

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.
