Retry Proxy Component for Operation Retry Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in efficiently managing operation retries, particularly in scenarios like accessing remote servers, where network failures lead to high server pressure and complex code structures due to the need for multiple retry attempts.
Innovation Solution
A method and system for operation retry that includes a retry proxy component with a strategy to determine if a retry is allowed, execute the operation, check for exceptions, and decide on subsequent retries based on predefined conditions and sleep times, decoupling business logic from retry logic to simplify code and manage server pressure effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple retry attempts are implemented using loop statements, then the reliability of obtaining user information is improved, but the server pressure increases and code complexity increases
Solution Approach 1:
The patent extracts the retry logic from the business code by introducing a separate RetryProxy component. This component handles all retry-related decisions and executions independently, allowing the business logic to remain simple while the retry mechanism manages complexity externally. The RetryProxy acts as an intermediary that extracts retry responsibilities from the main application flow.
Solution Approach 2:
The RetryProxy serves as an intermediary component between the business logic and the actual operation execution. It receives operations from the business layer, applies retry strategies, executes the operations with appropriate retry logic, and returns results to the business layer. This intermediary structure separates concerns and simplifies the overall system architecture.
2Reliability
If multiple retry attempts are implemented using loop statements, then the reliability of obtaining user information is improved, but the server pressure increases
Solution Approach 1:
The patent implements dynamic retry strategies where the RetryProxy adjusts retry behavior based on real-time conditions. It can determine whether to retry based on exception types, apply different retry counts for different operations, and dynamically manage retry state. This dynamic approach allows the system to optimize server pressure by retrying only when necessary and avoiding unnecessary retry attempts.
Solution Approach 2:
The RetryProxy incorporates feedback mechanisms to monitor operation outcomes and adjust retry decisions accordingly. It tracks whether operations succeed or fail, records retry histories, and uses this information to make intelligent decisions about whether to attempt retries. This feedback loop prevents blind retrying and optimizes server resource utilization.
3Ease of operation
If retry logic is integrated into business code, then the ease of operation is maintained, but the device complexity increases
Solution Approach 1:
The RetryProxy is designed as a universal component that can handle multiple types of operations (database queries, API calls, file operations, etc.) with a single unified structure. It provides multi-functional capabilities including retry decision-making, retry execution, error handling, and performance monitoring. This universality reduces code complexity by eliminating the need for separate retry logic for each operation type while maintaining ease of operation through a consistent interface.

AI summary
The present disclosure relates to systems and methods for operation retry. The system may determine whether a retry is allowed for a target operation based on a retry strategy included in a retry proxy component. In response to determining that the retry is allowed for the target operation, the system may execute the target operation. The system may detect whether there is an exception associated with the execution of the target operation. In response to determining that there is the exception associated with the execution of the target operation, the system may determine whether a retry is needed for the target operation based on the retry strategy. In response to determining that the retry is unneeded for the target operation, the system may stop the target operation.
