摘要： A script is run on a database to transform the metadata and produce an upgraded database. A new database corresponding to the upgraded database is initialized, and the metadata in the new database catalog is verified by comparing it to the upgraded database metadata. A fast verification is performed on a partial upgrade by dumping the catalogs of master nodes and comparing the results, and a thorough verification is performed on a full upgrade by querying and comparing both master node catalogs and segment node catalogs.

摘要： A process for upgrading a mirrored shared-nothing database system comprises a sequence of short well-defined idempotent steps, and at least one non-idempotent step involving transforming a master catalog. The upgrade process is managed and controlled by a state machine that has a persistent memory running on the master node. In the event of a failure or crash during an idempotent step, the process stops the database in the current state and repeats the step. If a failure or crash occurs during a non-idempotent step, the upgrade process is rolled back to the beginning and repeated.

摘要： A catalog of one or more metadata objects associated with metadata is stored in a persistent manner. The data objects are stored at least in part on a user node included in a data management system. A request associated with accessing a metadata object included in the persistent catalog is received. In response to receiving the request, access to the requested metadata object is provided.

摘要： Coarse-grained system-wide database privileges are transformed into new finer-grained database object privileges that are user-centric and specific to particular objects by creating an object class defining certain generic operations on objects, and defining within the object class a new object that embodies permissible actions on a particular database object. The new object is stored in a catalog table that comprises an object privilege table and is associated in the object privilege table with a consolidated grouping of object privileges of users relative to the new object.
摘要翻译： 粗粒度全系统的数据库权限通过创建一个定义对象的某些通用操作的对象类来转换为以用户为中心和特定于特定对象的新的更细粒度的数据库对象特权，并在对象类中定义一个新对象 体现了对特定数据库对象的允许操作。 新对象存储在包含对象特权表的目录表中，并且在对象特权表中与用户相对于新对象的对象特权的合并分组相关联。
