Worked on the apache/brpc repository to improve the accuracy and reliability of timing and latency measurements in backend systems. Focused on correcting sampler interval handling by switching from nanoseconds to microseconds, ensuring stable 1 Hz sampling and preventing erratic high-frequency events. Addressed inconsistencies in latency calculations by reverting the LocalityAwareLoadBalancer to use wall-clock time, aligning with caller expectations and eliminating silent failures. Added automated unit tests in C++ to validate consistent time source usage and accurate latency reporting. Collaborated on documentation and code changes, emphasizing performance optimization, system programming, and robust unit testing to enhance monitoring and load balancing stability.
