Abstract
Disclosed are a distributed storage system, a cluster node, and a range management method thereof, including: partitioning, by the cluster node according to a configuration parameter, a range corresponding to a first routing table entry in a local routing table into at least two subranges, where the first routing table entry refers to a routing table entry in which information that indicates the cluster node is recorded in replica information; separately establishing, by the cluster node, a log queue for each of the subranges; determining, by the cluster node, a corresponding subrange according to a key field of a data operation request from a client; executing a corresponding data read/write operation according to the determined subrange; and updating, according to the data read/write operation, a log queue corresponding to the determined subrange.
