Veli.yang

Over a three-month period, this developer enhanced cloud storage integration and backend reliability across the apache/amoro and apache/celeborn repositories. They delivered Alibaba Cloud OSS catalog support for Iceberg tables in amoro, updating configuration and build systems using Java and Scala. In celeborn, they improved S3 compatibility by refining schema recognition and restructured the multipart uploader for modular backend extensibility. Their work culminated in implementing Aliyun OSS multipart upload support, extending the MPU interface and adding a dedicated module to mirror AWS S3 integration. The developer demonstrated depth in backend development, configuration management, and distributed systems, addressing stability and extensibility challenges.

April 2025 monthly delivery focused on expanding cloud storage interoperability by delivering Aliyun OSS Multipart Upload Support for Celeborn (apache/celeborn). The feature extends the existing Multipart Uploader (MPU) interface and introduces a dedicated Aliyun OSS module with required configurations and dependencies to enable multipart uploads, mirroring the AWS S3 integration. This work is anchored by commit 7d0ba7f9b8f10f3e71b9356267ef00d7d7fc9771 ([CELEBORN-1916]). No major bugs were fixed this month; instead, the team progressed core capabilities and prepared for broader provider coverage. The overall impact includes increased storage provider flexibility, reduced vendor lock-in for customers, and a stronger value proposition for enterprise deployments in Alibaba Cloud regions.

March 2025 monthly summary for apache/celeborn: Focused work on reliability and modularity, delivering targeted improvements to S3 integration and backend extensibility. The month culminated in two critical landed changes: (1) bug fix in the Celeborn Shuffle Service to correctly recognize S3 storage types (s3a:// and s3://) improving compatibility and reliability, and (2) a refactor that relocates the multipart-uploader into multipart-uploader/multipart-uploader-s3, laying groundwork for supporting multiple object storage backends and cleaner module boundaries.
