Name

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

An enterprise-class RDBMS compatible with PostgreSQL and Oracle and widely used in China.

Popular in-memory data platform used as a cache, message broker, and database that can be deployed on-premises, across clouds, and hybrid environments

Redis focuses on performance so most of its design decisions prioritize high performance and very low latencies.
