Catalog support has been added to DSv2 along with a table catalog interface. Here I'd like to propose a view catalog interface, for the following benefit:
- Abstraction for view management thus allowing different view backends - Disassociation of view definition storage from Hive Metastore A catalog plugin can be both TableCatalog and ViewCatalog. Resolve an identifier as view first then table. More details in SPIP and PR if we decide to proceed. Here is a quick glance at the API: ViewCatalog interface: - loadView - listViews - createView - deleteView View interface: - name - originalSql - defaultCatalog - defaultNamespace - viewColumns - owner - createTime - softwareVersion - options (map) ViewColumn interface: - name - type Thanks, John Zhuge
