Created as commercial project in 2013, FoundationDB has been acquired by Apple in March 2015 and was withdrawn from the market. As a consequence, the product was removed from the DB-Engines ranking. In April 2018, Apple open-sourced FoundationDB and it therefore reappears in the ranking.
DescriptionFlash-optimized In-memory NoSQL DatabaseOrdered key-value store. Core features are complimented by layers.Distributed Event Store optimized for Internet of Things use casesPopular 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.a GPU-based, columnar RDBMS for big data analytics workloads
