    • Methods, systems, and apparatus, including computer programs encoded on computer storage media, for handling faults in a distributed key-value storage system. One of the methods includes receiving an indication that a machine storing a primary replica of a first replication chain is inactive, in response to receiving the indication, generating a concatenated replica comprising a first replica of the first replication chain and a second replica of a second replication chain, the second replication chain comprising replicas of a second key segment, the second key segment being adjacent to the first key segment in the multiple key segments of the plurality of keys, and providing, to another machine in the ordered sequence of machines, a notification of availability of the concatenated replica.
    • 方法,系统和装置,包括在计算机存储介质上编码的计算机程序,用于处理分布式键值存储系统中的故障。 响应于接收到该指示,接收指示,存储第一复制链的主副本的机器是不活动的,生成包括第一复制链的第一副本和第二副本的第二副本的级联副本 复制链,所述第二复制链包括第二密钥段的副本,所述第二密钥段与所述多个密钥的所述多个密钥段中的所述第一密钥段相邻,并且以所述有序顺序的机器提供给另一个机器, 通知连接的副本的可用性。
