Over seven months, Shuxu Li developed core features for the apache/iceberg-cpp repository, focusing on catalog management, authentication systems, and metadata access. Li implemented table metadata accessors and a refresh API to ensure reliable, up-to-date in-memory state, using C++ and CMake for robust integration and test coverage. They designed and refactored catalog interfaces to support table renaming and registration, improving maintainability and extensibility. Li also built authentication workflows for the REST catalog, including OAuth2 and Basic Auth, emphasizing secure, scalable access. Their work demonstrated depth in backend development, memory management, and system design, addressing both immediate functionality and long-term maintainability.

Mar 1, 2026March 2026: Delivered OAuth2-based authentication for the REST catalog in apache/iceberg-cpp, enabling secure, standards-based access via static tokens and the client_credentials flow. Implemented initial OAuth2Manager and established groundwork for token refresh and token exchange to support scalable integrations. This work is tracked under commit 72d3831e7be25b86f04c508d70c3e17029e77d68 (#577).

Nov 1, 2025Month 2025-11: Focused on architectural improvements in the iceberg-cpp catalog to strengthen table identity management and reduce maintenance burden. Delivered two key items: a Catalog Rename Tables Interface with in-memory implementation, and a refactor removing TableBuilder from the Catalog interface to reduce coupling. These changes enhance catalog reliability, enable safer table renames, and improve code maintainability for faster future iterations. No major user-facing bugs fixed this month; emphasis on long-term business value through robust APIs and cleaner code.

Aug 1, 2025August 2025: Delivered the Table Refresh API for metadata synchronization in apache/iceberg-cpp. Implemented a Refresh method on the Table class to reload metadata from the catalog, ensuring in-memory state reflects the latest catalog state. Added tests validating the refresh flow. This work improves metadata coherence, reduces stale reads, and strengthens reliability for metadata-heavy workloads.
