Message Broker Importance-Based Publication Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current publish/subscribe messaging systems lack flexibility in message publication control and feedback, failing to ensure that messages are delivered to a specific number of subscribers with required importance levels and do not provide adequate notification mechanisms for publishers when delivery criteria are not met.
Innovation Solution
A message broker system that receives messages with associated topics and classification criteria, selects subscribers based on registered subscriptions, and provides feedback to publishers on successful delivery, allowing for importance-level-based control and notification when delivery requirements are not met, using importance levels to determine successful publication and offering warn or fail modes for handling unsatisfied criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If message broker delivers messages to all registered subscribers without filtering, then message delivery speed is improved, but message delivery accuracy deteriorates
Solution Approach 1:
The message broker performs preliminary classification of subscribers based on importance levels before message delivery. Subscribers are pre-categorized into importance levels (e.g., high, medium, low), and the broker determines eligibility for delivery before actually sending messages. This preliminary sorting enables fast filtering without compromising delivery accuracy to the correct subscriber subset.
Solution Approach 2:
Different delivery rules are applied to different subscriber groups based on their importance levels. High-importance subscribers receive all messages, while medium and low-importance subscribers receive messages selectively based on classification criteria. This local differentiation of delivery quality resolves the contradiction by ensuring accuracy for each group while maintaining overall system speed.
2Reliability
If message broker implements classification criteria checking, then message delivery reliability is improved, but system complexity increases
Solution Approach 1:
Subscriber importance levels and classification criteria are established in advance during subscription registration. The message broker pre-configures delivery rules for each subscriber based on their importance level, so that during actual message delivery, the broker only needs to perform simple comparisons rather than complex real-time evaluations. This preliminary setup reduces runtime complexity while maintaining reliability.
Solution Approach 2:
The system uses importance level parameters (e.g., integer values or categorical levels) to represent subscriber priority. These parameters are assigned during subscription and used as simple comparison keys during message routing. By transforming complex subscriber requirements into simple parameter-based rules, the system achieves reliable delivery without excessive complexity.
3Loss of information
If message broker provides detailed delivery feedback to publishers, then information completeness is improved, but communication overhead increases
Solution Approach 1:
The feedback mechanism extracts only the essential delivery information and sends it back to the publisher. Instead of providing complete delivery logs for all subscribers, the broker extracts key metrics such as delivery status (success/failure), number of delivered messages, and criteria met/not met. This selective extraction provides sufficient information for publisher decision-making while minimizing communication overhead.
Solution Approach 2:
The system provides partial feedback by default (basic delivery status) and can provide additional detailed feedback only when needed. The publisher receives essential delivery information in all cases, with the option to request more detailed feedback for specific messages or situations. This partial feedback approach reduces routine communication overhead while maintaining information completeness when required.

AI summary
Control and/or feedback are provided for message publication in a publish/subscribe messaging environment. A number of different aspects are disclosed, and an embodiment may include one or more of these aspects. In each aspect, each subscribing application has an associated importance level for a subscription, and this importance level may vary among subscriptions for different message topics. Each published message has an associated topic. In some aspects, each published message also has associated criteria, where the criteria are specified with regard to message classification. In preferred embodiments, the message classification comprises importance criteria specifying requirements for importance level of subscribers registered for the topic of that message. Feedback can be provided regarding whether a message publication meets the importance criteria. Control over message publication can be based on whether a message publication meets the importance criteria.
