Event-Driven API Callback Using Message Queues for Data Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face inefficiencies when clients continuously request information that is not yet available, leading to resource drain and frustration, as they typically time out or receive error messages.
Innovation Solution
Implement an asynchronous event-based callback system that transmits data to clients upon the occurrence of a predetermined event, using message queues with enhanced security through encryption and location-matched security keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clients continuously send requests for information that is not yet available, then the client can obtain the data once it becomes available, but system resources are drained and client experience deteriorates due to timeouts and error messages
Solution Approach 1:
The system performs preliminary actions by registering event subscriptions and setting up callback mechanisms in advance. When data becomes available, the pre-configured event handlers automatically trigger data transmission without requiring continuous client requests, thus ensuring reliable delivery while avoiding resource waste from repeated polling attempts
Solution Approach 2:
The system implements feedback mechanisms through event-driven architecture where the server notifies clients automatically when data becomes available. This feedback loop eliminates the need for continuous client requests and ensures that data is delivered reliably as soon as it is ready, optimizing both reliability and resource efficiency
2Productivity
If asynchronous event-based callback is implemented, then resource efficiency improves and client frustration reduces, but system complexity increases due to event registration and message queue management
Solution Approach 1:
The system introduces message queues as intermediary components between clients and data sources. These queues manage event subscriptions and data transmission asynchronously, decoupling the complexity of event handling from both clients and data providers while maintaining high system efficiency through standardized message passing protocols
3Reliability
If message encryption and security key matching are implemented, then communication security improves, but processing time and computational overhead increase
Solution Approach 1:
Security keys and encryption parameters are established in advance during event registration. This preliminary setup allows the system to use pre-configured security credentials for subsequent message transmissions, ensuring strong encryption and authentication while minimizing processing time during actual data exchange operations
Data Source
AI summary
A method, computer program product, and computer system for receiving, at a computing device, a request for data from a client electronic device. It may be determined that the data is not currently available upon receiving the request for the data. It may be determined that an event associated with the data has been triggered, wherein the event indicates availability of the data. A message containing the data may be transmitted to the client electronic device, wherein the message containing the data is asynchronously transmitted to the client electronic device based upon, at least in part, triggering of the event.
