Wuyanxing focused on backend development and bug fixing in the crossoverJie/starrocks repository, addressing a memory management issue within the CatalogRecycleBin component. By analyzing the root cause of high memory usage during deletion tasks, Wuyanxing implemented a Java-based solution that removed completed table and partition deletion tasks from internal tracking maps, effectively reducing the memory footprint during cleanup operations. To ensure reliability, they expanded test coverage and introduced helper methods for verifying proper task removal, emphasizing robust testing practices. This work improved the stability of memory management during bulk deletions and laid a foundation for safer, more maintainable future changes.
