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.
