August 2025 monthly summary for apache/brpc focused on delivering observability and control improvements that directly enhance reliability, performance management, and client-side SLA adherence. Key feature delivered: expose RPC reception time in microseconds and provide a timeout control API. Specifically, the changes add rpc_received_us recording during RPC processing and introduce new API methods Controller.set_rpc_received_us and Controller.get_rpc_received_us to expose precise timing to users. Major bugs fixed: none reported this month for this repo; effort concentrated on feature delivery with clear business value. Overall impact: improved observability, accurate timeout handling, and capacity to discard timed-out RPCs earlier, enabling more predictable performance and better resource utilization. Technologies/skills demonstrated: C++ code changes, API design for operational visibility, low-overhead instrumentation, and robust RPC processing path improvements.
