Interface CatalogProvider

All Superinterfaces:

AutoCloseable

All Known Implementing Classes:

InMemoryCatalogProvider, ModelBackedCatalogProvider

public interface CatalogProvider
extends AutoCloseable

Lifecycle-bearing source of catalog metadata.

Plan §7.2 / §10.1. Static-file readers funnel through UnifiedCatalogModel into ModelBackedCatalogProvider; live sources (JDBC, Hive, Glue, Unity) implement this interface directly.

Phase 1A skeleton — implementations land in P1B (T1B.7).
