Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for setting feature flags are labor-consuming, time-consuming, and resource-intensive due to their limited support for multiple programming languages, making it difficult for developers to manage feature flags across different applications and locations.
Innovation Solution
A method and system for generating a target feature flag file with a predetermined data format, converting it into multiple target codes for various programming languages, and querying the corresponding code for a client's programming language to efficiently configure feature flags across different applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional solution is used for setting feature flags, then specific programming languages can be supported, but it becomes labor-consuming, time-consuming, and resource-consuming to set feature flags in different locations and programming languages for different applications
Solution Approach 1:
The patent creates a universal feature flag management system that generates code libraries supporting multiple programming languages (Java, C++, C#, Python, Go) from a single configuration source. This allows the same feature flag configuration to be used across different applications written in different languages, eliminating the need for separate configuration processes for each language and application, thereby resolving the contradiction between multi-language support and configuration efficiency
Solution Approach 2:
The system generates target code libraries by converting a single feature flag configuration into multiple language-specific implementations. Instead of manually creating feature flag settings for each programming language, the system automatically copies and adapts the configuration into appropriate code formats for different languages, significantly reducing the labor and time required while maintaining support for multiple programming languages
2Reliability
If separate solutions are created for each programming language, then each language can be properly supported, but the process becomes very labor-consuming, time-consuming, and resource-consuming
Solution Approach 1:
The system performs preliminary action by pre-generating language-specific code libraries from a single configuration file before deployment. The feature flag configurations are converted into ready-to-use code snippets for multiple programming languages in advance, so that when applications need feature flags, they can directly use the pre-generated code without manual configuration, thereby reducing time loss while ensuring language-specific accuracy
Solution Approach 2:
The patent introduces an intermediary conversion system that acts as a mediator between the single source configuration and multiple target programming languages. This intermediary automatically translates the configuration into language-appropriate code formats, ensuring each language receives properly formatted code while eliminating the need for manual time-consuming configuration for each language, thus resolving the contradiction between code accuracy and time consumption
Data Source
AI summary
Techniques for setting feature flags involve generating a target feature flag file with a predetermined data format, the target feature flag file indicating a name and a target state of a target feature. Such techniques further involve generating a feature state query library of the target feature flag by converting the target feature flag file into a plurality of target codes corresponding to a plurality of target programming languages. Such techniques further involve querying, from the feature state query library, a target code corresponding to a target programming language used by a client in the plurality of target programming languages. Such techniques further involve sending the queried target code to the client, the target code indicating the target state of the target feature.
