Round Robin Database is a database that typically holds cyclical data points and remains a constant size over time.

A Round Robin Database is primarily used for monitoring purposes and usually contains time-series data such as network bandwidth, temperatures, and CPU load. The data is stored in the way that system storage footprint remains constant over time as newer data overwrites similar older data. This avoids resource expensive purge jobs and reduces complexity.
