US Patent 10891264 Distributed, scalable key-value store

Techniques for implementing a distributed, scalable key-value store (DSKVS) across a plurality of nodes are provided. In one embodiment, each node in the plurality of nodes can store: (1) a hash table in a nonvolatile storage of the node, where the hash table is configured to hold a partition of a total set of key-value data maintained by the DSKVS; (2) a logical log in the nonvolatile storage, where the logical log is configured to hold transaction log records corresponding to key-value update operations performed on the node; and (3) a cache in a volatile memory of the node, where the cache is configured to hold key-value data that has been recently updated on the node via one or more of the key-value update operations.
