DescriptionReal-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.An ultra-fast, open source Key-value store fully compatible with Redis API, modules, and protocolsPopular in-memory data platform used as a cache, message broker, and database that can be deployed on-premises, across clouds, and hybrid environments infoRedis focuses on performance so most of its design decisions prioritize high performance and very low latencies.
