Materializable database objects in multitenant environments

Techniques and solutions are described for facilitating the distribution of tables and table data between a shared container and one or more tenant containers. The tables can include a sharing indicator that can designate a table (or a view on a table) as having a materializable type. Materializable types can initially be deployed in the shared container, and a tenant container can have read access to the table via a view. If the tenant attempts to modify the materializable table, the table can be materialized in the tenant container. Metadata for a materializable table can include materialization instructions. Techniques and solutions are also provided for converting between sharing types, and for updating shared containers or table schemas.
