Aerospike is an open source, distributed NoSQL database and key-value store built to achieve speed at scale out on commodity hardware. Aerospike is commonly used as a key-value store, cache replacement, user profile store, recommendation engine, and fraud detection use cases.

Features

  • An operational NoSQL database with simple real-time analytics capabilities built in.
  • A fast key value store with support for complex objects, user defined functions and distributed queries.
