Linwb developed JVM memory metrics collection for the crossoverJie/starrocks repository, focusing on backend observability and system monitoring. They designed and implemented new C++ modules to gather JVM memory data, integrating this logic into the existing StarRocks metrics framework. The solution included a configuration option to enable or disable JVM metrics, allowing teams to balance observability needs with system overhead. By leveraging C++, Java, and JNI, Linwb enabled more effective JVM troubleshooting, incident diagnosis, and capacity planning. The work demonstrated depth in backend development and metrics instrumentation, aligning with StarRocks’ strategy for improved system visibility and operational efficiency.
