Key-value store with internal key-value storage interface

A distributed key-value store, comprising:

• a plurality of compute nodes connected by a network, wherein at least one of said compute nodes comprises a partitioned key-value store server;
• wherein the partitioned key-value store server is configured to store key-value data using a local key-value store, wherein keys in said key-value data comprise semantic information, said local key-value store comprising an abstract storage interface comprising a software interface module that communicates with at least one persistent storage device providing a key-value interface for persistent storage of one or more key-value pairs, wherein said software interface module provides said one or more key-value pairs to said at least one persistent storage device in a key-value format that maintains said semantic information of said keys in said key-value pairs.

A method comprising:

• providing a key-value store server on at least one compute node of a distributed storage system for storing a plurality of key-value pairs, wherein keys in said key-value pairs comprise semantic information;
• and
• communicating with at least one persistent storage device providing a key-value interface for persistent storage of one or more of said plurality of key-value pairs using an abstract storage interface comprising a software interface module, wherein said software interface module provides said one or more key-value pairs to said at least one persistent storage device in a key-value format that maintains said semantic information of said keys in said key-value pairs.
