DescriptionFlash-optimized In-memory NoSQL DatabaseDatomic builds on immutable values, supports point-in-time queries and uses 3rd party systems for durabilityHarperDB takes the "stack" out of "tech stack" by combining an ultra-fast document-style data store, in-memory cache, real-time message broker, and your application components into a single distributed technology.Popular 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.
