Aerospike is the company behind the Aerospike open source NoSQL distributed database which has a horizontally scalable high-speed lightweight data layer. Citrusleaf, a Mountain View, California based company which rebranded to Aerospike in August 2012, launched the database in 2011.〔(【引用サイトリンク】title=AeroSpike, the former Citrusleaf )〕〔(【引用サイトリンク】title=Citrusleaf used for Real-time Attribution )〕 The company purpose-built the database for developers to deploy real-time big data applications.〔 According to a study by Wikibon in 2012, Aerospike is the leading data-in-flash database for transactional analytic applications, and it can answer over 200 thousand transactions per second per node.〔 Additionally, with automatic fail-over, replication, and cross data center synchronization, the Aerospike database can store terabytes of data.〔〔(【引用サイトリンク】url=http://www.thumbtack.net/solutions/documents/Ultra-HighPerformanceNoSQLBenchmarking.pdf )〕〔(【引用サイトリンク】url=http://siliconangle.com/blog/2013/04/02/aerospike-beats-out-cassandra-couchbase-mongodb-handles-node-failure-like-a-champ/ )〕〔(【引用サイトリンク】url=http://wikibon.org/wiki/v/Flash_and_Hyperscale_Changing_Database_and_System_Design_Forever )〕 The database is primarily used in advertising as a server-side cookie store, where read and write performance is paramount.〔〔 It forms the core user data storage for adMarketplace and several other advertising companies including BlueKai, Tapad, The Trade Desk, Sony's So-net, and eXelate. The database is also used in gaming, security, and e-commerce industries.〔 ==History== Aerospike, formerly known as Citrusleaf, was founded in 2009 by database and networking industry veterans CTO Brian Bulkowski and Vice President of Engineering & Operations Srini V. Srinivasan.〔〔〔 The company rebranded to Aerospike in 2012.〔 In August 2012, Aerospike acquired the database AlchemyDB. AlchemyDB, led by Russell Sullivan, is a hybrid RDBMS/NoSQL-datastore that has been optimized for memory efficiency.〔〔 Aerospike made the acquisition with funding from New Enterprise Associates|NEA, Draper Associates, Columbus Nova Technology Partners, and Alsop Louie Partners.〔 In December 2012, online ad broker Tapad bought an Aerospike flash-based NoSQL database running on SSDs with indices held in RAM.〔〔 The Aerospike database allowed Tapad the cost benefit of dealing with memory as a "single level store" by utilizing flash as a memory extension.〔 In June 2014. Aerospike raised $20 million in a Series C round of funding. The company also announced that it had open sourced its technology. The company also partnered with Adform, InMobi, and Vizury in 2014.
