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： Described is a technology in which an anchor value is determined, for example to synchronize a destination database or data store with modifications made to a source database. The new anchor value is determined in a manner that excludes modifications corresponding to any uncommitted transactions. The new anchor value may be based on a counter value or a date and time value stored with each modification. The new anchor value may be determined by comparing a first set of committed modifications that do not include uncommitted modifications against a second set of modifications that includes committed modifications and uncommitted modifications. Alternatively, the new anchor value may be determined from the earliest start date and time among the modifications that are part of any uncommitted transactions. The anchor may be used (e.g., via queries) to enumerate modifications for synchronization, and also for detecting conflicts between the source and destination databases.
摘要翻译：描述了一种技术，其中确定锚值，例如使目标数据库或数据存储与对源数据库的修改同步。新的锚点值以排除与任何未提交交易相对应的修改的方式确定。新的锚值可以基于每个修改存储的计数器值或日期和时间值。可以通过将不包括未提交的修改的第一组提交的修改与包括已提交的修改和未提交的修改的第二组修改进行比较来确定新的锚值。或者，可以从作为任何未提交事务的一部分的修改中的最早开始日期和时间来确定新的锚点值。可以使用锚点（例如，经由查询）来枚举用于同步的修改，并且还用于检测源数据库和目的地数据库之间的冲突。

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： Various embodiments of the present invention are directed to synchronization utilizing one or more optimizations through the utilization of metadata. For several embodiments of the present invention, one method for optimizing synchronization is to reduce the overhead required for said synchronization by having each peer only tracking changes for itself and other peers within its change community (or communities) (a.k.a., “Intra-Community-Only Change Tracking Optimization”). For certain embodiments of the present invention, another method for optimizing synchronization is to not create synchronization overhead until required. For numerous embodiments of the present invention, yet another method for optimizing synchronization is to minimize redundant use of a partner's unique global ID—a large and cumbersome number—and to instead maintain a table that cross-references each partner (and its unique global ID) with a smaller and much less cumbersome partner key.

摘要： The subject invention pertains to data synchronization across replicas. Disclosed are systems and methods of detecting and handling constraint-based conflicts that occur during a synchronization session. In accordance with one particular aspect of the invention, name-constraint violations can be detected. These violations can be resolved by generating a single merged identity that can be utilized to refer to data units, for example on different replicas that had the same name. A property of the merged identity can be merge history, which specifies the identifiers subsumed by the merge.

摘要： Systems, methods, and computer program products for synchronizing items at replicas within a topology is disclosed. Items are stored in physical tables at the replicas. The physical table layouts at each replica can differ but are mapped to a common logical view. When a replica receives an indication that synchronization should be performed, the replica determines if changes have been made at the replica that should be mapped to the logical views. Replicas can facilitate this by comparing local change enumerations for changes made in physical tables to synchronization local change enumerations for changes in the logical views. Any changes that need to be synchronized are sent through the logical views to other replicas in the topology.

摘要： A computer operated apparatus estimates values needed by an optimizer in a database management system (DBMS). The DBMS has one or more tables for storing data, each table having zero or more columns of user-definable data types and zero or more associated user-defined routines (UDRs). The apparatus has a feature vector extractor connected to the database tables for converting the UDR inputs into a base type representation. A neural network receives the feature vector and generates estimated values which are provided to the optimizer of the DBMS. The neural network can be trained periodically using randomly generated queries, or it can be trained dynamically by capturing data generated during a query. During operation, the optimizer dynamically invokes the neural network to generate estimates such as selectivity and cost per call for determining optimum query search sequence.
