摘要： Atomic multiple modifications of streams is provided. Streams are selected for the application of an atomic multiple modification. A lock is acquired on the meta-data associated with the streams. Each stream is de-coupled from its name. Multiple modifications are applied to the selected streams. After performing the modifications, names are coupled to the streams. The lock on the meta-data associated with each stream is released.
摘要翻译： 提供了流的原子多重修改。 选择流用于原子多重修改的应用。 在与流相关联的元数据上获取锁。 每个流从其名称中去耦合。 对所选择的流应用多个修改。 执行修改后，名称与流相连。 与每个流相关联的元数据的锁定被释放。

摘要： Replica placement in a network of nodes is provided. Nodes are selected for replica placement to satisfy location-based preferences. Additionally, nodes are selected for replica placement to spread replicas of the same data over different fault domains and upgrade domains. In some instances, nodes may be selected for replica placement based on load-based information for the nodes.
摘要翻译： 提供了节点网络中的副本放置。 为复制放置选择节点以满足基于位置的偏好。 另外，选择节点进行复制放置，以在不同的故障域和升级域上扩展相同数据的副本。 在一些情况下，可以基于用于节点的基于负载的信息来选择用于副本放置的节点。
