Developed a Unified Remote Storage Configuration API for the apache/celeborn repository, introducing a centralized remoteStorageDirs method to streamline configuration across HDFS, S3, and OSS backends. This refactor reduced duplication and simplified the process of adding new storage types, enhancing both scalability and maintainability. The work focused on backend development and configuration management, leveraging Java and Scala to abstract multi-storage integration and improve configuration governance. By consolidating remote storage configuration logic, the changes enabled faster delivery of new cloud storage features and laid the groundwork for future extensibility, addressing the needs of distributed systems without introducing new bugs.
