摘要:
Optimistic concurrency is effectuated to manage constraints in a synchronization environment at multiple computing device endpoints in a consistent fashion without utilizing concentrated centralized constraint logic. Implemented data synchronization constraints that identify false violation scenarios may be automatically resolved without user intervention by using an etag system directed by a master component to assist computing device endpoints to maintain data synchronization among them. Data entries defining each file hierarchy component to be synched are generated and shared with the master component and each computing device endpoint in a synchronization environment. Individual computing device endpoints can use the data entries generated locally with those generated by other computing device endpoints to locally resolve identified false violation scenarios.

A user interface for building a componentized workflow model. Each step of the workflow is modeled as an activity that has metadata to describe design time aspects, compile time aspects, and runtime aspects of the workflow step. A user selects and arranges the activities to create the workflow via the user interface. The metadata associated with each of the activities in the workflow is collected to create a persistent representation of the workflow. Users extend the workflow model by authoring custom activities.
摘要:
Systems and methods for synchronizing data between endpoints, including the modification of data on an endpoint without necessarily modifying data that is communicated between endpoints are disclosed. In such systems and methods the representation of data on an endpoint may be modified so that constraints on that particular endpoint are enforced, without requiring a similar or the same modification to the data when it is synchronized to other endpoints.

Asynchronous fault handling for a workflow. A state automaton for an activity in the workflow is defined. The state automaton includes at least an executing state, a faulting state, and a closed state and classifies an execution lifetime of the activity. The activity is defined to include work items and includes an execution hierarchy for the work items. Each work item includes an operation for executing a portion of the activity. Each work item is transitioned to the executing state. The included operation of transitioned work items is executed in the executing state. One or more of the transitioned work items are identified in response to the faulting event as a function of the execution hierarchy and the included operation. The faulting event is asynchronously handled by transitioning the one or more identified work items to the faulting state while executing the included operation of the remaining transitioned work items.

Building a componentized workflow model via an application programming interface. Each step of the workflow is modeled as an activity that has metadata to describe design time aspects, compile time aspects, and runtime aspects of the workflow step. A user selects and arranges the activities to create the workflow via the application programming interfaces. The metadata associated with each of the activities in the workflow is collected to create a persistent representation of the workflow. Users extend the workflow model by authoring custom activities. Users also compile the workflow via the application programming interface.

Data files, applications and/or corresponding user interfaces may be accessed at a device that collaborates in a mesh. The mesh may include any number or type of devices that collaborate in a network. Data, applications and/or corresponding user interfaces may be stored within a core object that may be shared over the mesh. Information in the core object may be identified with a corresponding user such that a user may use any collaborating device in the mesh to access the information. In one example, the information is stored remotely from a device used to access the information. A remote source may store the desired information or may determine the storage location of the desired information in the mesh and may further provide the desired information to a corresponding user.

摘要:
The present invention provides a novel technique for Web-based asynchronous processing of synchronous requests. The systems and methods of the present invention utilize a synchronous interface in order to couple with systems that synchronously communicate (e.g., to submit queries and receive results). The interface enables reception of synchronous requests, which are queued and parsed amongst subscribed processing servers within a server farm. Respective servers can serially and/or concurrently process the request and/or portions thereof via a dynamic balancing approach. Such approach distributes the request to servers based on server load, wherein respective portions can be re-allocated as server load changes. Results can be correlated with the request, aggregated, and returned such that it appears to the requester that the request was synchronously serviced. The foregoing mitigates the need for clients to perform client-side aggregation of asynchronous results.

Systems and methods of distributed storage are disclosed herein. A request to store data in a client computer is received. A request is sent from the client computer to a storage service to create a core object such that the core object can be created with a member entry to a member feed in the core object. The member feed can be indicative of one or more entities that are permitted to access to the core object. A message is received at the client computer with the core object. A replica of the core object on the client computer is created. The client computer can add the data as a data entry to a data feed in the core object. An updating message is sent to the storage service. The message can include a copy of the replica of the core object including the data entry.
