Developed a configurable tap sampling feature for the envoyproxy/envoy repository, focusing on enhancing observability while minimizing system overhead. The work introduced tap_enabled sampling for both HTTP and transport socket taps, allowing users to specify a sample rate that determines the fraction of requests or connections evaluated for tapping. By recording the configured sample rate in the TraceWrapper, the implementation provided improved visibility into the sampling process, supporting more effective debugging and performance analysis. This feature was built using C++ and leveraged skills in API and backend development, balancing the need for detailed observability with the goal of reducing unnecessary tapping activity.
