Key Value Database Example. Databases supporting key-value stores persist the data to a disk serving the database files while a key-value cache implementation will mostly keep the data loaded in memoryIn case of a server fault or restart the data needs to be preloaded into the cache as it was not persistent. The basic data structure is a dictionary or map. A key-value database stores data as a collection of key-value pairs in which a key serves as a unique identifier. The key-value pair concept is also commonly known as Entity Attribute Value EAV.
