Event Producer System for Real-Time Message Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing social media messaging platforms face challenges in efficiently processing and delivering real-time messages over large message streams while managing computer resources and ensuring security, particularly in handling fluctuating query subscriptions and maintaining user privacy.
Innovation Solution
The system employs a modular approach with a subscription executor and a transport engine to manage query subscriptions separately from message delivery, utilizing event producers and a collector service to control resource allocation and streaming rates, and applies visibility rules to ensure secure message delivery based on user permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single integrated system is used to manage query subscriptions and deliver messages, then device complexity is reduced, but message delivery speed and resource management efficiency deteriorate
Solution Approach 1:
The system is divided into distinct modules: a subscription manager module that handles query subscription management and an event delivery module that handles message delivery. This segmentation allows each module to specialize in its function, improving processing efficiency and message delivery speed while maintaining manageable system complexity through clear separation of concerns.
2Productivity
If resource allocation is tightly controlled to manage fluctuating query subscriptions, then computer resource management efficiency is improved, but message delivery speed deteriorates
Solution Approach 1:
The system implements dynamic resource allocation where the subscription manager can adjust resource allocation based on the current number of active query subscriptions and system load conditions. This allows the system to efficiently manage fluctuating query subscriptions while maintaining adequate message delivery speed by adapting resource allocation in real-time rather than using fixed allocation.
3Reliability
If security checks are performed on all messages from all users, then security is improved, but processing speed deteriorates
Solution Approach 1:
The system performs preliminary security configuration by establishing visibility rules and user restrictions in advance. The subscription manager configures security parameters before message delivery occurs, allowing the event delivery module to quickly filter messages based on pre-established security criteria rather than performing comprehensive security checks on every message in real-time, thus maintaining both security and processing speed.

AI summary
This disclosure relates to streaming real-time messages over time to client applications according to query subscriptions that match content from a large stream of messages exchanged on a messaging platform in a manner that increases the speed of message delivery, effectively controls the management of computer resources to handle the fluctuation of the number of active query subscriptions, and/or increases the security of matching the query subscriptions against messages generated from the perspective of the authors while delivering those messages in real-time from the perspective of the users that initiated the query subscriptions.
