摘要： A protocol for replicating replicas in a sync community. Each replica maintains a knowledge that represents changes that the replica is aware of. Each replica does not typically maintain knowledge about other replicas. The protocol includes messages that include knowledge about changes on the various replicas. Using the knowledge, the replicas can enumerate changes and send the changes using asynchronous messages that do not need to be received in any particular order. The protocol enables filters to ensure that a valid replication is possible using a minimum knowledge argument. The protocol also enables replicas to partially replicate using filtered knowledge.

摘要： Various embodiments of the present invention are directed to conflict handling for conflicts that occur in a peer-to-peer synchronization system, where the ability to correctly and efficiently handle conflicts minimizes data loss while retaining good usability and reduces the need for user intervention during synchronization. Conflict handling in the synchronization service is divided into three stages: (1) conflict detection; (2) automatic conflict resolution and logging; and (3) conflict inspection and resolution. Certain embodiments are directed to a conflict handling schema comprising one or more of the follow conflict handling elements: (a) schematized representation of conflicts; (b) detection of conflicts; (c) logging of conflicts into a durable store; (d) automatic resolution of conflicts according to a flexible and configurable azqsxqxwdconflict resolution policy; (e) composable and extensible conflict handlers to filter and resolve conflicts; (f) automatic detection and removal of obsolete conflicts; and (g) programmatic conflict resolutions.

摘要： Various embodiments of the present invention are directed to systems and method for detecting conflicts and applying conflict resolutions during manual and automatic conflict resolution operations. Several embodiments are directed to preventing both: (a) non-convergence of conflict resolutions, where partners can end up in a divergent steady state (i.e. have different data in the absence of outstanding conflicts); and (b) a non-terminating ping-pong of conflict resolutions between partners (which can occur with certain inefficient solutions that continuously update metadata for each conflict resolution without end). Certain specific embodiments of the present invention are directed to a method for maintaining knowledge that guarantees convergence of data, even when different partners apply different conflict resolutions.
摘要翻译：本发明的各种实施例涉及用于在手动和自动冲突解决操作期间检测冲突和应用冲突解决方案的系统和方法。若干实施方案的目的在于防止：（a）冲突解决的不一致性，其中合作伙伴最终可能处于不同的稳定状态（即在没有未决冲突的情况下具有不同的数据）; （b）合作伙伴之间的冲突解决方案不能终止乒乓球（可能会出现某些无效解决方案，不间断地更新每个冲突解决方案的元数据而无需结束）。本发明的某些具体实施例涉及一种用于维护知识的方法，以保证数据的收敛，即使当不同的合作伙伴应用不同的冲突解决方案时。

摘要： A system and method for synchronizing a database comprising raw data and metadata derived from the raw data, but when the metadata has not yet been updated. The raw data and the metadata are first synchronized, with the raw data having been assigned a version number. After synchronization, any stale metadata will be updated and assigned the same version number as the raw data.

摘要： Various embodiments of the present invention are directed to systems and methods for synchronizing mixed elements (MEs) comprising structure data and unstructured filestreams between peer computer systems in a hardware/software interface system environment that does not permit snapshotting of large unstructured ME filestreams during synchronization. For several such embodiments, the method comprises synchronizing the ME in two steps, one for snapshotting the structured data component of the ME (as well as the cv of the filestream but not the filestream itself) and one for locking and transmitting the filestream to the receiving sync peer if and only if, after being locked, it is determined that the filestream is unchanged from the time of the ME data component snapshot.

摘要： Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.

摘要： Several embodiments of the present invention employ synchronization adapters for synchronizing information between “WinFS” and non-“WinFS” data sources. Examples of adapters include an adapter that synchronizes address book information between a “WinFS” contacts folder and a non-WinFS mailbox. In these instances, adapter developers might use the “WinFS” synchronization core services API described herein for accessing services provided by the “WinFS” synchronization platform in order to develop schema transformation code between the “WinFS” schema and the non-“WinFS” data source schema. Additionally, the adapter developer provides protocol support for communicating changes with the non-“WinFS” data source. A synchronization adapter is invoked and controlled by using the synchronization controller API and reports progress and errors using this API.

摘要： Systems and methods for synchronizing data stores. A framework including a sync runtime enables consistent and manageable synchronization between a data store and multiple, diverse back end data stores. The sync runtime provides services such as change enumeration, conflict detection, metadata management, item ID matching, sync interruptability, and the like that are accessible to configurable adapters over an application programming interface. Each synchronizing data store can uses a sync controller to initialize an adapter that can access the services provided by the sync runtime. The sync controller can use a profile to configure each adapter. The profile can identify conflict resolution policies, synchronization filters, source and destination folders, sync direction, and the like.

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.
