Key-value Store
Key-value store (KVS) is a method for storing and managing data in a memory device. The stored data (i.e., the "value") and the key information for identifying that data (i.e., the "key") are stored as a pair. When the data is retrieved, the key (defined when the data was stored) is assigned and invoked.
Since KVS is a simple storage and management method specialized for storage and retrieval of data, it features a high degree of system expandability.
Furthermore, from the viewpoint of high reliability, KVS (which can store and manage data with multiply distributed storage locations) is specifically known as "distributed KVS".
