Handler read lastDocumentation00

Handler read retryDocumentation00
Handler read rndDocumentation30.5 M30461634The number of requests to read a row based on a fixed position. This is high if you are doing a lot of queries that require sorting of the result. You probably have a lot of queries that require MySQL to scan whole tables or you have joins that don't use keys properly.
Handler read rnd deletedDocumentation289.7 k289709
Handler read rnd nextDocumentation4.4 G4366877091The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans.
