Abstract: 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.

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.

Abstract: Architecture that defines a logical database that shares physical resources with a containing physical database. The architecture isolates the relational engine system metadata parts of a database in horizontal scopes to form separate namespaces, and shares the underlying storage engine system metadata. Sharing physical database resources enables efficient input/output (I/O) utilization and instantaneous database creation and growth. In addition, logical databases can be backed up as a single transactionally consistent unit.

Abstract: 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.

Abstract: Work item rules for a work item tracking system are provided. Work item rules may be accessible, usable and subject to interpretation by multiple software entities. Further, work item rules may be configured to be subject to creation and change by users, for example, by exposure to users through a user interface. A work item rule may specify an identifier by which the abstraction can be identified and/or a name, and may specify, or be indicative of, a condition and an action to be taken if the condition is satisfied. In response to a first user action affecting a first work item rule, one or more work item rules corresponding to the first user and/or the first work item may be determined. The one or more work item rules then may be interpreted, and the user action responded to based on the interpretation.

Abstract: Embodiments are directed to providing database access during database reconfiguration and to maintaining replication connections during database reconfiguration. In an embodiment, a computer system establishes multiple quorum sets of replicas to replicate the data of a data partition. The quorum sets of replicas ensure that at least a minimum number of replicas are operating to commit pending transactions during partition reconfiguration. The computer system determines that a data partition reconfiguration has been initiated and provides access to the data partition's data during reconfiguration of the data partition using at least a quorum of replicas in each of the quorum sets of replicas.

Abstract: Database management architecture for recovering from failures by building additional replicas and catching up replicas after a failure. A replica includes both the schema and the associated data. Modifications are captured, as performed by a primary replica (after the modifications have been performed), and sent asynchronously to secondary replicas. Acknowledgement by a quorum of the replicas (e.g., primary, secondaries) at transaction commit time is then awaited, and desired to be obtained. The logging of changes for recovery from failures is implemented, as well as online copying (e.g., accepting modifications during the copy) of the data when replica catch-up is not possible. Modifications can be sent asynchronously to the secondary replicas and in parallel.
