DescriptionAn open source immutable (append-only) database with cryptographic verification which makes it tamper-resistant and fully auditable.QpenQM is a high-performance, self-tuning, multi-value DBMSWidely used in-process key-value storeIndustry 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.
