DescriptionMicrosofts flagship relational DBMSOpen Source Operational and Transactional Enterprise NoSQL Document DatabasePopular 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 key-value store forked from RocksDB with advanced compression algorithms. It can be used standalone or as a storage engine for MySQL and MongoDBOLTP DBMS based on a distributed architecture and highly compatible with MySQL and Oracle
