DescriptionNatively in-memory DBMS with options for persistency, high-availability and clusteringIn-memory key-value store, originally intended for cachingAn open source graph database built for real-time streaming and compatible with Neo4jIndustry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database. infoThe data is stored in a circular buffer, thus the system storage footprint remains constant over time.
