Catalog replication preserves table definitions across regions or environments as part of Iceberg disaster recovery. It must coordinate with data-file replication because copied metadata may still reference the original storage location. section 11.3.3
A reliable replication workflow must account for:
- Replicating catalog state or version history alongside object-storage data files, manifests, and snapshot metadata. section 11.3.3
- Rewriting absolute metadata paths so the replicated table points to storage in the destination region. section 11.3.3
- Planning isolation across development, staging, and production to prevent recovery operations from damaging shared catalogs. section 11.3.3
Cross-region Iceberg recovery
Amazon S3, Azure, and Google Cloud can replicate files across regions, but the resulting Iceberg backup needs coordinated catalog preservation and metadata rewriting before it becomes usable. section 11.3.3
