Abstract

A key-value store for storing and retrieving user files based on key-value pairs, hereafter referred to as KVPs. For each user of the key-value store, each file of a set of files of said each user is stored as one or more pairs of KVPs. Each of said one or more pairs comprises a KVP of a first type and a KVP of a second type. The KVP of the first type comprises at least a part of contents of said each file, whereas the KVP of the second type comprises metadata (and possibly attributes) of said each file. Each KVP of the second type links to one or more KVPs of the first type. Further provided are related method and computer program products.
