摘要： Architecture that provides the capability to automatically (e.g., dynamically) reorganize (repartition) an existing partition by dividing (splitting) or recombining (merging) logical databases. This reorganization can be performed to logical databases belonging to the same customer, and based on the partitioning of the tables in these databases. This can include not only splitting secondary replicas of a partition or merging secondary replicas of the partition, but also splitting off secondary replicas of the partition to create a new partition and merging two partitions into one partition. Moreover, these operations can occur while the logical databases are accepting workload (online).
摘要翻译：提供通过划分（分割）或重组（合并）逻辑数据库来自动（例如，动态地）重新组织（重新分配）现有分区的能力的架构。可以对属于同一客户的逻辑数据库执行此重组，并且基于这些数据库中的表的分区。这不仅可以分割分区的次要副本或合并分区的副副本，还可以分割分区的辅助副本，以创建新分区，并将两个分区合并成一个分区。而且，当逻辑数据库接受工作负载（在线）时，可能会发生这些操作。

摘要： Architecture that eliminates the need for on-disk full backups of data retaining only changes that have occurred, in a separate table. Thus, the architecture provides for incremental recovery of incremental changes in a relational database (e.g., SQL). The architecture provides improved recovery time and recovery point objectives. By using the incremental capture of changed data (e.g., in an XML format), the capability is provided to capture schema changes, query the incremental change data and efficiently restore user data to an earlier point-in-time state. Changes (e.g., insert, update and delete operations) are tracked (e.g., continuously) by a set of triggers and the incrementally captured changed rows are inserted in a data capture table (a differential change “delta” table) in a human-readable format (e.g., XML). Rollback is also provided.
摘要翻译：架构，消除了在单独的表中仅保留已发生的更改的数据的磁盘完全备份的数据。因此，架构提供了关系数据库（例如，SQL）中增量更改的增量恢复。该架构提供了改进的恢复时间和恢复点目标。通过使用改变的数据的增量捕获（例如，以XML格式），提供能力来捕获模式改变，查询增量变化数据并有效地将用户数据恢复到较早的时间点状态。通过一组触发器跟踪（例如，插入，更新和删除操作）更改（例如，连续地），并且增量捕获的改变的行被插入到人类可读的数据捕获表（差分变化“delta”表）中格式（例如，XML）。还提供回滚。

摘要： Embodiments are directed to providing distributed database service upgrades of database server instances in a computer cluster using multiple database server instances and to monitoring and maintaining a distributed database service during upgrade. In an embodiment, each computer system in a computer cluster instantiates at least two different database server instances on each of the nodes in the cluster. The first database server instances are configured to operate using a current distributed database version and the second instances are configured to operate using a new, updated distributed database service version. The computer system receives an indication that the distributed database service is to be upgraded. Then, based on the received indication, the computer system migrates database replicas from the first database server instances to the second database server instances which operate the new, updated service version, substantially without user-visible downtime.
摘要翻译：实施例旨在使用多个数据库服务器实例在计算机集群中提供数据库服务器实例的分布式数据库服务升级，并在升级期间监视和维护分布式数据库服务。在一个实施例中，计算机集群中的每个计算机系统在群集中的每个节点上实例化至少两个不同的数据库服务器实例。第一个数据库服务器实例被配置为使用当前分布式数据库版本进行操作，第二个实例被配置为使用新的更新的分布式数据库服务版本进行操作。计算机系统接收到分布式数据库服务将被升级的指示。然后，基于收到的指示，计算机系统将数据库副本从第一数据库服务器实例迁移到操作新的更新服务版本的第二数据库服务器实例，基本上没有用户可见的停机时间。

摘要： The present invention extends to methods, systems, and computer program products for partitioning online databases. Online database operations, such as, for example, SPLIT, MERGE, and DROP, are used to alter the arrangement of partitions in a federated database. A SPLIT operation splits rows at one partition across a plurality of other partitions. A MERGE operation merges rows at a plurality of partitions in to one partition. A DROP operation shifts responsibility for rows of data from one partition to another partition and then drops the rows from the one partition.
摘要翻译：本发明扩展到用于分割在线数据库的方法，系统和计算机程序产品。在线数据库操作（例如SPLIT，MERGE和DROP）用于更改联合数据库中分区的排列。 SPLIT操作分割跨越多个其他分区的一个分区的行。 MERGE操作将多个分区中的行合并到一个分区。 DROP操作将从一个分区的数据行的责任转移到另一个分区，然后从一个分区中删除行。

摘要： A method for work-item tracking, in a computer system that includes client computers and at least one server maintaining a database, includes defining at least one work item, associating version identifiers with corresponding versions of at least one work item, and storing, in the database, work-item data. The work-item data can include the current version of the work item, one or more prior versions of the work item, and the version identifiers. A computer readable medium is encoded with a program that, when executed, can perform the method for work-item tracking.

摘要： A database is queried as of any wall-clock time within a retention period, via undo that uses database snapshots and a list of page level modifications. The snapshot is user-identified, automatically generated, or extracted from a backup. The list is maintained in a transaction log by persisting page content before a page is re-used, persisting deleted rows before they are moved, persisting compensation log record undo information, and/or logging a full page. To rewind an entire database, the undo scans the transaction log in reverse LSN order and undoes all page modifications. Undo reverses reallocated pages, table truncation, and/or table deletion, as well as page-level modifications of a schema, metadata values, and/or system tables. An as-of query is handled using as-of page(s) from a sparse page file. If the sparse page file does not already contain the responsive page(s), they are created and added to it.
摘要翻译：通过使用数据库快照和页面级修改列表的撤销，在保留期内的任何挂钟时间查询数据库。快照是用户标识，自动生成或从备份中提取的。该列表通过在重新使用页面之前持久页面内容来维护事务日志，在删除的行移动之前保留已删除的行，持久化补偿日志记录撤消信息和/或记录完整页面。要倒退整个数据库，undo以反向LSN顺序扫描事务日志，并撤消所有页面修改。撤消反转重新分配的页面，表截断和/或表删除，以及模式，元数据值和/或系统表的页面级修改。使用从稀疏页面文件中的页面处理一个查询。如果稀疏页面文件尚未包含响应页面，则会创建它们并将其添加到其中。

摘要： The subject invention relates to systems and/or methods that perform an authoritative and/or a non-authoritative restore of items in a data store. Backups are provided that include data associated with items and metadata related to the items that can include a history of operations and previous synchronizations to enable replications to converge after restoration. The operations that can be performed on the items include, for example, create, delete, update, move, etc. The items in the backups can be restored along with the metadata, which can be utilized to enable synchronization partners to converge based on a desired type of restoration.

摘要： Extending hierarchical synchronization (sync) scopes to non-hierarchical scenarios may involve a method for synchronizing differently organized data stores comprising mapping different physical organizations to similar logical organizations and utilizing an organization-based synchronization algorithm to synchronize the differently organized stores. Also, the uniqueness constraints of the organizations may be preserved as well as the parent-child ordering constraints of the organizations.

摘要： Disclosed are systems and methods pertaining to data synchronization and move handling support. In particular, a move log is maintained that identifies data that has moved in, out, and within a synchronization scope. Furthermore, the log comprises times associated with when data moves in and out of the synchronization scope. Systems and methods can interact easily with the generated and updated move log to facilitate determining data versions and identifying new data that may need to be synchronized.
摘要翻译：公开了与数据同步和移动处理支持有关的系统和方法。特别地，维护移动日志，其标识已移入，移出和在同步范围内的数据。此外，日志包括当数据移入和移出同步范围时相关联的时间。系统和方法可以与生成和更新的移动日志轻松交互，以便于确定数据版本并识别可能需要同步的新数据。
