Review Comment:
   The name here doesn't quite seem right. The "Metastore" part of the catalog this extends indicates it is for building Hive or similar catalogs -- and it's been around long enough that people generally know what it is so keeping that part would make sense to me. This name only tells me that this is used for views, without the relevant information that it is based on the `BaseMetastoreCatalog` for tables.
   
   I'd recommend something like `BaseMetastoreViewCatalog`.
