Cymen's Blog : MySQL and Round Robin Database (RRD) While looking for a MySQL RRD storage engine, I came across Round-Robin Database Storage Engine (RRD) (pdf) which describes how to setup a MySQL table to act as a RRD. The PDF appears to have been created in February of 2007 but the benchmark result at the end of 600 inserts/second says this was achieved on a 1350 MHz AMD CPU which suggests the article may be older. I replicated the configuration and tested it on my laptop (5400 RPM disk, 2.4 GHz Intel T7700 CPU). With the MyISAM database, a brieft test of about 50k inserts resulted in ~7000 inserts/second. But the 25m max rows means the trigger functionality (the part that makes the table behave like an RRD) wasn’t really tested. By henrikin Developmentwith databasemysqlround-robinrrd
