Name

Description

Wide-column store based on ideas of BigTable and DynamoDB

Optimized for write access

Open-Source and Enterprise in-memory Key-Value Store

Time Series DBMS based on Cassandra

RDF4J is a Java framework for processing RDF data, supporting both memory-based and a disk-based storage.

MySQL wire-compliant distributed RDBMS that combines an in-memory row-oriented and a disc-based column-oriented storage with patented universal storage to handle transactional and analytical workloads in one single table type
