Abstract: A recovery consumer framework provides for execution of recovery actions by one or more recovery consumers to enable efficient recovery of information (e.g., data and metadata) in a storage system after a failure event (e.g., a power failure). The recovery consumer framework permits concurrent execution of recovery actions so as to reduce recovery time (i.e., duration) for the storage system. The recovery consumer framework may coordinate (e.g., notify) the recovery consumers to serialize execution of the recovery actions by those recovery consumers having a dependency while allowing concurrent execution between recovery consumers having no dependency relationship. Each recovery consumer may register with the framework to associate a dependency on one or more of the other recovery consumers. The dependency association may be represented as a directed graph where each vertex of the graph represents a recovery consumer and each directed edge of the graph represents a dependency. The framework may traverse (i.e., walk) the framework graph and for each vertex encountered, notify the associated recovery consumer to initiate its respective recovery actions.

Abstract translation: 恢复消费者框架提供了一个或多个恢复消费者执行恢复动作以使得能够在故障事件（例如电源故障）之后有效地恢复存储系统中的信息（例如，数据和元数据）。 恢复消费者框架允许并发执行恢复动作，以减少存储系统的恢复时间（即，持续时间）。 恢复消费者框架可以协调（例如，通知）恢复消费者以使具有依赖性的那些恢复消费者对恢复动作的执行进行序列化，同时允许没有依赖关系的恢复消费者之间的并发执行。 每个恢复消费者可以向框架注册以将依赖关系与一个或多个其他恢复消费者相关联。 依赖关联可以表示为有向图，其中图的每个顶点表示恢复消费者，并且图的每个有向边代表依赖性。 框架可以遍历（即，走）框架图，并且对于遇到的每个顶点，通知相关联的恢复消费者以启动其各自的恢复动作。

Abstract: One or more techniques and/or systems are provided for multicast transport configuration, for multicast transport, and/or for fault policy implementation. In an example, a multicast component may receive a data copy request from an application to copy data to multiple destinations. A scheduler component may create a transport schedule specifying an order with which to facilitate data copy operations across transports, such as heterogeneous transports, to the destinations. A dispatcher component may apply application specified transport modifiers to the data copy operations (e.g., a modification to a quality of service for a transport). The dispatcher component may facilitate the data copy operations and provide operation result information to a policy agent. The policy agent may provide notifications of data copy operation statuses from the operation result information and/or may implement a fault policy (e.g., a retry on a different transport) for a data copy operation that experienced a fault.

Abstract translation: 提供了一种或多种技术和/或系统用于多播传输配置，用于多播传输和/或用于故障策略实现。 在一个示例中，多播组件可以从应用程序接收数据复制请求，以将数据复制到多个目的地。 调度器组件可以创建指定顺序的传输调度，以便促进跨传输（诸如异构传输）到目的地的数据复制操作。 调度器组件可以将应用指定的传输修改器应用于数据复制操作（例如，对于传输的服务质量的修改）。 调度器组件可以促进数据复制操作，并向策略代理提供操作结果信息。 策略代理可以从运行结果信息提供数据复制操作状态的通知和/或可以对经历故障的数据复制操作实施故障策略（例如，在不同的传输上重试）。
