Worked on wundergraph/cosmo to deliver a configurable minimum response size for compression, enabling operators to fine-tune bandwidth and CPU usage per deployment. Implemented the response_compression_min_size option in the router’s traffic configuration, updating core backend logic in Go to honor this setting and adding comprehensive tests to ensure correct behavior across scenarios. Enhanced maintainability by documenting the new configuration in wundergraph/cosmo-docs using Markdown, clarifying supported units and default values for users. Focused on backend development, configuration management, and testing, this work improved performance flexibility and operator control without introducing new bugs, emphasizing reliability and clear knowledge transfer.
