Application Synchronization Service Delivery Guarantee
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing application synchronization services face challenges in ensuring reliable and efficient delivery of notifications about data modifications to subscribers without impacting end-to-end message delivery latency or throughput, and with minimal operational overhead, while maintaining quality of service and avoiding message failures.
Innovation Solution
A hierarchical distributed system utilizing parallelization and memory queues to manage notifications, coupled with a push notification service as a centralized failure queue, ensures level one quality of service compliance by reducing thread and memory contention and mitigating dependent service outages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a push notification service is implemented to ensure reliable message delivery, then message delivery reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a push notification service as an intermediary component between the application synchronization service and subscribers. This mediator handles the complexity of reliable message delivery (including retry logic, failure queues, and quality of service guarantees) independently, allowing the core application synchronization service to remain simple while achieving high reliability through the specialized notification service infrastructure.
2Reliability
If quality of service guarantees are implemented for message delivery, then message delivery success is improved, but message delivery latency increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring quality of service levels and failure queue mechanisms before message delivery is needed. The push notification service is pre-established with retry logic and failure handling protocols in place, allowing messages to be delivered quickly when conditions permit while having backup mechanisms ready but not actively consuming time during successful deliveries.
3Ease of operation
If a hierarchical distributed system with parallelization is used to manage notifications, then operational overhead is reduced, but system complexity increases
Solution Approach 1:
The notification management system is segmented into a hierarchical distributed architecture with multiple independent components operating in parallel. Each node in the distributed system handles specific notification tasks independently, allowing the system to scale horizontally and reduce operational overhead through parallel processing while the modular segmentation manages complexity by isolating functions into discrete, manageable units.
Data Source
AI summary
Techniques for delivery guarantee compliance for an application synchronization service are described. In certain embodiments, a publishing service utilizes its memory queue to receive a request to publish a notification of a modification of a monitored data source from an application synchronization service, and then sends a success code to the application synchronization service based at least in part on the storing of the request to publish the notification in the memory queue. Embodiments herein are directed to a publishing service that delivers messages with a level one Quality of Service (QOS) that indicates that a message will be delivered one time at least.
