########## format/view-spec.md: ########## @@ -82,9 +97,12 @@ Each version in `versions` is a struct with the following fields: | _required_ | `representations` | A list of [representations](#representations) for the view definition | | _optional_ | `default-catalog` | Catalog name to use when a reference in the SELECT does not contain a catalog | | _required_ | `default-namespace` | Namespace to use when a reference in the SELECT is a single identifier | +| _optional_ | `storage-table` | A [storage table identifier](#storage-table-identifier) of the storage table | When `default-catalog` is `null` or not set, the catalog in which the view is stored must be used as the default catalog. +When `storage-table` is `null` or not set, the entity is a common view, otherwise it is a materialized view. The storage table must be in the same catalog as the materialized view. Review Comment: If we allow other catalogs, we need to store their names. And if we include the "catalog" name, we get the issue that different query engines might resolve it differently. That's why we restrict it to the same catalog and avoid storing catalog identifiers in the metadata. -- This is an automated message from the Apache Git Service.
