Description

Distributed Database based on Lucene

Industrial-strength, open-source database solution built from the ground up for event sourcing.

RDBMS for high security requirements

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.
