Description
This PR introduces
CatalogManagedSnapshotManager, the catalog-backed counterpart toPathBasedSnapshotManager, so Unity Catalog tables can route snapshot reconstruction through UC commit APIs while path tables keep existing behavior.SnapshotManagerFactorynow selects the appropriate implementation andSparkTableis wired to use the factory, enabling transparent switching based on catalog metadata. The manager loads ratified commits throughUCClient, builds Kernel snapshots with staged commit data, and delegates commit-range and history queries to UC-aware logic. New tests exercise the manager end-to-end using the sharedcatalog-owned-previewdataset to ensure streaming/time-travel semantics stay intact.How was this patch tested?
