Abstract: A data storage system may be configured to allocate replica-sets in a balanced manner and mark some of these balanced replica-sets as being spares. As one or more drives or machines fail, the data storage system may move all copies of an affected replica-set to a marked spare replica-set and mark the affected replica-set as being inactive or invalid. As the failed drives are replaced, the data storage system may reconfigure those inactive replica-sets and use them as new spares. The data storage system may implement a coordinator module that handles the balancing and allocation of spares within a sub-cluster. The coordinator may also reallocate entire replica-sets across sub-clusters to maintain balance at the cluster level.

Abstract: Methods and systems for simulating a search, for the purpose of evaluating one or more scoring functions used in ordering item listings for presentation in a search results page are described. Consistent with some embodiments, a simulation platform includes a real-time simulation module that receives search result sets for search queries that result in the conclusion of a transaction. The result set is then processed by the simulation platform with one or more test scoring functions, such that the resulting position of the item listing that has resulted in the transaction can be compared with the actual position at which the item listing was displayed in the actual search results. For each test scoring function, an average rank shift metric is determined, and displayed, thereby providing a metric with which to base decisions about which scoring functions to use in the production system.

Abstract: In various example embodiments, a system and method for managing a server cluster are provided. An example method may include scheduling a first job on a first node, using a first resource manager, establishing a service for a second resource manager on a second node, wherein the service is allocated node resources of the second node, and attempting to schedule a second job on the first node, using the first resource manager. The method may include preempting the service on the second node, using the second resource manager, in response to the attempt to schedule the second job on the first node, and deallocating the node resources of the second node from the service. The method may include advertising, using a node manager of the first resource manager, available node resources of the second node, and scheduling the second job on the second node, using the first resource manager.

Abstract translation: 数据存储系统可以被配置为以平衡的方式分配副本集，并将这些平衡副本集中的一些标记为备用。 当一个或多个驱动器或计算机出现故障时，数据存储系统可将受影响的副本集的所有副本移动到标记的备用副本集，并将受影响的副本集标记为不活动或无效。 当更换失败的驱动器时，数据存储系统可以重新配置那些不活动的副本集并将其用作新的备件。 数据存储系统可以实现一个协调器模块，该协调器模块处理子集群内备件的平衡和分配。 协调器还可以跨子群集重新分配整个副本集，以在群集级别保持平衡。
