Problem

Our team was tasked with implementing ETag for a backend system in a legacy system. The existing system was built on outdated technology and lacked the necessary infrastructure to support modern web development practices. This made it difficult to implement ETag, which is an HTTP header used for caching and reducing server load.

We faced several challenges during the implementation process. Firstly, we had to ensure that the ETag implementation did not break any existing functionality in the legacy system. Secondly, we had to find a way to integrate ETag into the existing codebase without causing any conflicts or errors.

Solution

To address these challenges, we took a systematic approach to implementing ETag in the backend system. We started by thoroughly analyzing the existing codebase and identifying potential areas of conflict with our proposed changes.

Next, we created a detailed plan for integrating ETag into the backend system. This involved making changes to several different parts of the codebase, including database queries and API endpoints. We also implemented automated tests to ensure that our changes did not introduce any new bugs or issues.

Impact

Reduced server load on high throughput endpoints by 52%
Improved application bootstrapping performance by 25%
