Overview

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.
  • The first in-memory NoSQL database optimized for flash (indexes in DRAM and data in DRAM or natively stored on flash devices) with dramatic price/performance benefits.
  • A distributed database with a shared-nothing, clustered architecture and single row ACID properties. Aerospike ensures high availability, replicating data synchronously within clusters and asynchronously across data centers.
  • The system of engagement for personalized and revenue critical user interactions, Aerospike was architected to scale with zero touch and zero downtime operations.
