US Patent 12066998 Online updates to schema information in multi-tenant database system

Techniques are disclosed relating to updating schema information for multi-tenant databases. In some embodiments, a multi-tenant database system stores a standard schema for a database object, where the standard schema is shared by multiple tenants and a tenant-specific schema for the database object. The tenant-specific schema may include one or more tenant-specific custom elements for the database object. The system may enforce a naming scheme in which tenant-specific elements include a predetermined pattern that is not included in object elements of the standard schema. The system may, in response to detecting an update of the standard schema, automatically propagate the update to the tenant schema, while the tenant is online.
