Worked on expanding the Iceberg REST API within the apache/iceberg repository by introducing new endpoints for resource existence checks and operations related to table credentials and scan plans. Focused on API development using Java, the work emphasized an API-first approach, defining clear and traceable RESTful services to support automated resource management and safer data access. The implementation laid the groundwork for future integrations and governance by ensuring that namespaces, tables, and views could be programmatically verified and managed. This feature-driven contribution enhanced the API’s capabilities, enabling more robust interaction with Iceberg data resources while maintaining a strong focus on maintainability.
