Worked on the apache/gravitino repository to deliver a cross-schema Hive table renaming feature, enabling tables to be moved between databases or schemas within the Hive catalog. This involved updating APIs and catalog logic in Java to support explicit new schema handling and ensure metadata was correctly transferred to the target location. The implementation included compilation-safe integration with the Hive Metastore client pool and comprehensive end-to-end validation through new integration tests. By focusing on backend development and testing, this work enhanced data lifecycle flexibility, streamlined multi-tenant catalog management, and reduced the need for manual reconfiguration when organizing Hive tables across schemas.
