Aerospike is a flash-optimized in-memory open source NoSQL database and the name of the company that produces it.[1]

History

Aerospike Database was first known as Citrusleaf 2.0. In August 2012, the company rebranded both the company and software name to Aerospike.[2] The name Aerospike is derived from a type of rocket nozzle that is able to maintain its output efficiency over a large range of altitudes, and is intended to refer to the software's ability to scale up.[3] In 2012, Aerospike acquired AlchemyDB, and integrated the two databases' functions, including the addition of a relational data management system.[4] On June 24, 2014, Aerospike was opensourced under the AGPL 3.0 license for the Aerospike database server and the Apache License Version 2.0 for its Aerospike client software development kit.[5][6][7] In February 2015, Aerospike named John Dillon, previously of Salesforce.com, as its new CEO.[8]

Features

Aerospike Database is written in C, and operates in three layers: a flash optimized data layer, a self-managed distribution layer and a cluster-aware client layer.[9] The distribution layer is replicated across data centers to ensure consistency.[9] The replication also allows the database to remain operational when an individual server node fails or is removed from the cluster.[9] The smart client layer is used to track the cluster configuration in the database, and manages communications in the server node.[9]

The data layer in Aerospike Database is optimized to store data in solid state drives, RAM, or traditional rotational media.[2] The database indices are stored in RAM for quick availability, and data writes are optimized through large block writes to reduce latency.[9] The software also employs two sub-programs that are codenamed Defragmenter and Evictor.[9][10] Defragmenter removes data blocks that have been deleted, and Evictor frees RAM space by removing references to expired records.[9]
