PROFILE
Wangshisan
Gangge Wang contributed backend enhancements to the pinterest/starrocks and crossoverJie/starrocks repositories, focusing on performance and reliability. He refactored the SystemInfoService in Java to use streams for backend ID filtering, reducing redundant calls and improving the efficiency of SHOW PROC statistics, which supports scalability in large clusters. Additionally, he addressed concurrency issues in the User Function Cache by implementing a guard to prevent race conditions during shared UDF loading, thereby increasing the reliability of analytics workloads. His work demonstrated depth in backend development, concurrency control, and caching, with careful attention to system performance and robust bug-fix practices in C++ and Java.
