Hi Nicholas, I think Gravitino and Polaris are complementary by addressing different use cases.
Gravitino is focusing on metadata lake with metadata features (metadata management, metadata governance, geo-distribution, AI asset management). Polaris is focusing on Apache Iceberg REST Catalog implementation, with associated features (RBAC, auth, etc). So, I see extensions from one to another (in both ways) but not the same use cases.
