Data sovereignty makes stored and processed data subject to the laws and governance requirements of its jurisdiction. In an Iceberg lakehouse, this often means distributing catalogs across regions, clouds, or business units while preserving a unified discovery and access experience. section 7.2.6
A sovereignty-aware catalog mesh should:
- Keep local control over data residency, encryption, auditability, namespaces, access policies, and metadata operations. section 7.2.6
- Provide consistent metadata APIs, namespace resolution, identity propagation, and change synchronization across catalog boundaries. section 7.2.6
- Pair compliant storage with operational safeguards such as encryption, retention, access controls, and audit logging. section 5.4.10
Regional government deployment
A government agency can use AWS GovCloud or Azure Government for regulated cloud workloads, or deploy Ceph, MinIO, or Dell ECS on premises when infrastructure control and residency requirements dominate. section 5.5.4
