Name

Description

Real-time database for speed, scale, and savings. Millisecond latency for mixed read/write workloads. Highly distributed. Proven strong consistency. Distributed ACID Transactions. Flash optimized for low cost of ownership and scalability. Aerospike Database is a shared-nothing, multi-threaded, multi-model data platform designed to operate efficiently on a cluster of server nodes, exploiting modern hardware and network technologies to drive reliably fast performance, at sub-millisecond speeds across petabytes of data.

A high-performance, column-oriented SQL DBMS for online analytical processing (OLAP) that uses all available system resources to their full potential to process each analytical query as fast as possible. It is available as both an open-source software and a cloud offering.
