- Reduced memory consumption within the database by 4% by identifying patterns and creating rules for storing specific utility fields.
- Rewrote over 80% of the logic in the high-load administrative microservice to achieve improved performance. This was accomplished by rethinking the data processing logic, resulting in significant performance enhancements. The optimization efforts allowed for the launch pods to be allocated up to 60% of the initial memory capacity.
- Improved the performance of the information retrieval algorithm by reducing the number of database queries from microservices from N*3 to 4 queries, resulting in information processing time decreasing from 40-70 seconds to <5 seconds.
