Abstract
Embodiments of the present invention provide an approach for a broker-assisted, publisher side cache that can be utilized to reduce a volume of data (e.g., network traffic) delivered between a publisher and broker in a publication/subscription (pub/sub) environment. Specifically, in a typical embodiment, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. Such data can be determined from historical messages (e.g., determining that a certain set of data appeared in multiple messages and is thus flagged in a database or the like), a set of rules (e.g., if data set “Y” appears, flag it as potentially repetitive), etc. Regardless, once such a set of data has been identified, a unique identifier/key corresponding thereto will be sent back to the publisher system and the set of data will be stored in a (data) cache. Upon receipt, the publisher system will cache/store the unique identifier in a (key) cache. Then, when the publisher system generates a future message that would contain the same set of data, the publisher system will substitute the unique identifier (as retrieved from the key cache) fo…
