    Abstract: 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.

    Abstract: 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.

    Abstract: 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).

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。 更改（例如，插入，更新和删除操作）被一组触发器跟踪（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。

    Abstract: 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.
