Glassdoor has decreased latency overhead and improved data monitoring by integrating with WhyLabs. The challenge of integration latency was addressed by optimizing the whylogs open-source data logging library, which resulted in a significant reduction of latency overhead from 68 ms to 8 ms. This case study highlights the importance of examining the implementation of functions being integrated into services and demonstrates that ML observability can be lightweight while still providing valuable insights for Glassdoor's ML systems.
