摘要： An episodic execution of program instances and a coordinated message exchange protocol are combined to achieve eventual consistency in the communication between nodes of a distributed system. Program instances run in episodic loops that are triggered by defined input events and that generate checkpoints. The checkpoints indicate when messages are to be sent from the one instance to another instance or other device. The coordinated message exchange protocol allows the instance to send a message to a receiver, to acknowledge that the message has been received, and to confirm the acknowledgement to the receiver.

摘要： Enabling creation of control flow patterns in a workflow via continuations. Each continuation represents an activity execution context for an activity executing in the workflow by a workflow engine virtualizing a managed execution environment. Responsive to a request, the activity execution context is recreated via the continuation and the activity is executed within the recreated context.

摘要： 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.

摘要： A distributed instance system manages instances and communications between the instances. The distributed instance system provides a restricted set of communication methods to the instances. Based on the type of communication method used, the distributed instance system has knowledge of the messages sent by instances and can make decisions on how to handle the messages. When one of the instances involved in a message exchange ends, the host uses its knowledge of the message exchange type to determine whether to drop the message, drop a reply to the message, and/or send an error message to the surviving instance. An instance may create one or more child instances in a tree-like configuration. Status data is passed up the tree from children instances and aggregated in the parent instances. Monitoring data may be generated from the aggregated status data.
摘要翻译：分布式实例系统管理实例之间的实例和通信。分布式实例系统为实例提供了一组有限的通信方法。基于所使用的通信方式的类型，分布式实例系统知道实例发送的消息，并且可以对如何处理消息做出决定。当消息交换涉及的实例之一结束时，主机利用其对消息交换类型的知识来确定是否删除消息，丢弃对消息的回复和/或向幸存的实例发送错误消息。实例可以以类似树的配置创建一个或多个子实例。状态数据从树实例传递给子实例，并在父实例中聚合。可以从聚合状态数据生成监视数据。

摘要： Declaratively canceling execution of an activity. A state automaton for an activity is defined, and the state automaton includes an executing state, a canceling state, and a closed state and classifies an execution lifetime of the activity. The activity includes work items and organizes the work items in an execution hierarchical structure. The work items are transitioned from the executing state to the closed state indicating a completion of executing the each work item of the activity. Upon having one of the work items being transitioned to the closed state, a cancellation request is transmitted to the work items currently in the executing state. The executing work items are identified as a function of the transmitted cancellation request and the execution hierarchical structure of the defined activity. The execution lifetime of the activity is canceled by transitioning the identified work items from the executing state to the canceling state.
摘要翻译：声明地取消活动的执行。定义用于活动的状态自动机，并且状态自动机包括执行状态，取消状态和关闭状态，并对活动的执行寿命进行分类。活动包括工作项目，并以执行层次结构组织工作项目。工作项目从执行状态转换到关闭状态，指示执行活动的每个工作项目的完成。当一个工作项目被转换到关闭状态时，将取消请求发送到当前处于执行状态的工作项目。执行的工作项目被确定为所发送的取消请求和定义的活动的执行分层结构的函数。通过将识别的工作项从执行状态转换到取消状态来消除活动的执行寿命。
