Publisher-based message data cashing 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:
- evaluating a publication rate of messages pertaining to a set of topics;
identifying a set of data in a first message received on a broker system from a publisher system, the set of data having a potential to appear in at least one future message based on the set of data pertaining to at least one topic of the set of topics, the at least one topic of the set of topics having a higher publication rate than other topics of the set of topics;
sending a unique identifier corresponding to the set of data from the broker system to the publisher system and a subscriber system, the unique identifier identifying the set of data as cacheable;
receiving a second message on the broker system from the publisher system, the second message having the unique identifier;
sending the message with the identifier to the subscriber system;
retrieving the set of data from a cache at the subscriber system; and
replacing the unique identifier in the second message with the set of data to yield a completed message at the subscriber system.

Abstract
An approach for caching potentially repetitive message data in a publication/subscription messaging environment is provided. Specifically, when a message is received on a broker system from a publisher system, the broker system analyzes the message for potentially repetitive data. 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) for the set of data to yield an abbreviated/truncated message.
