PROFILE

Meteorgan

Gan worked extensively on cloud storage and database infrastructure, contributing to the apache/opendal and tursodatabase/turso repositories. Over thirteen months, Gan delivered features such as recursive delete for ADLS and HDFS, batch versioned deletion, and SQL engine enhancements like VALUES, LIMIT, INTERSECT, and EXCEPT support. Using Rust and SQL, Gan focused on backend development, API design, and system programming, implementing robust error handling, metadata propagation, and integration with services like AWS S3 and Azure Blob. The work emphasized maintainability through documentation, CI/CD improvements, and code refactoring, resulting in more reliable storage operations and streamlined developer workflows across platforms.

During January 2026, delivered two priority features for the apache/opendal repository and tightened storage operations and deployment flexibility. Implemented Recursive Delete for Cloud Storage across ADLS (with Hierarchical Namespace support) and HDFS, enabling directory-and-contents deletion in a single operation with input-driven behavior and performance considerations. Also added Azurite Deployment Flexibility by configuring Docker Compose to skip API version checks to remove version-constraint friction. These changes improve data lifecycle management and local/dev deployment agility.

Feb 1, 2025

February 2025 focused on reliability and consistency across cloud storage integrations, delivering robust path handling, write metadata semantics, and safer S3 interactions. Key features were implemented across three repositories to improve data integrity and developer experience: (1) apache/opendal — Google Drive path normalization bug fix to remove trailing slashes in directory creation/querying, preventing Drive API inconsistencies; (2) apache/opendal — write operation metadata return and writer refactor to return Metadata (content length, ETag, version ID) and propagate it through bindings and tests; (3) apache/arrow-rs-object-store — enable default conditional put operations for Amazon S3 by introducing a Disabled variant and adjusting PutMode logic; (4) apache/arrow-rs — enable default conditional S3 puts by default using ETagMatch and reflect changes in PutMode Create/Update. These changes collectively improve data integrity, API consistency, and robustness of cloud storage interactions, reducing operational risk and improving bindings/test reliability.

Jan 1, 2025

January 2025 monthly recap for apache/opendal: Delivered a set of capabilities that improve data access correctness, performance, and data analytics workflows, while tightening CI reliability and test coverage. The work focused on making reads and stat operations cache-friendly via HTTP conditional requests, expanding object-store capabilities with Put/Get options and conditional GET, and returning authoritative metadata right after writes. An example workflow demonstrates DataFusion usage with OpenDAL’s object_store, and CI/test infrastructure was enhanced to enable robust, faster feedback on changes. Key business/value outcomes: reduced latency and unnecessary data transfer through conditional requests; safer, more flexible object store ops with PutMode and conditional GET; immediate visibility into write results via ETag/version_id, enabling stronger consistency guarantees; easier data analytics pipelines with an end-to-end DataFusion example; more reliable CI that speeds up releases and reduces wasted runs. Technologies/skills demonstrated: HTTP conditional headers (If-Match/If-None-Match/If-Modified-Since/If-Unmodified-Since), DataFusion integration, object_store Put/Get options, metadata semantics (ETag/version_id), GitHub Actions CI, integration testing, and documentation-for-ops alignment.
