DescriptionIn-memory key-value store, originally intended for cachingWidely used open source RDBMSQpenQM is a high-performance, self-tuning, multi-value DBMSWidely used RDBMSIndustry 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.
