MariaDB ColumnStore provides a column-oriented storage engine and MariaDB Xpand supports distributed SQL.Industry 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.
