Key-Value stores: a practical overview Marc Seeger Computer Science and Media Ultra-Large-Sites SS09 Stuttgart, Germany September 21, 2009 Abstract Key-Value stores provide a high performance alternative to rela- tional database systems when it comes to storing and acessing data. FASTER is a single-node shared memory key-value store library that makes two important technical innovations: It proposes a cache-friendly and concurrent latch-free hash index designed to grow and shrink dynamically while maintaining logical pointers to records in a log. The basic operations are Put(key,value), Get(key), Delete(key). It is used as default storage subsystem of H2, but it can also be used directly within an application, without using JDBC or SQL. Managing large application state easily, resiliently, and with high performance is one of the hardest Writing data at the speed of 160 MB/s and reading it at 80 MB/s, Badger is the fastest LSM Tree-based Key-Value Store written in Go. These are simple examples, but the aim is to provide an idea of the how a key-value database works. I need to store simple key-value string/string pairs (not documents or JSON, just strings). . A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.Dictionaries contain a collection of objects, or records, which in turn have many different fields within them, each containing data. KV databases save data as a group of key-value pairs, which are made up of two linked data items. What's the fastest key-value store that can read without locks that can be shared among processes.Redis is slow (only 2M ops), hashmaps are better but not really multi-processes friendly.
