Handler read lastDocumentation2.7 k2680
Handler read nextDocumentation98.2 M98179020The number of requests to read the next row in key order. This is incremented if you are querying an index column with a range constraint or if you are doing an index scan.

Handler read retryDocumentation00
Handler read rndDocumentation227.7 k227657The 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 deletedDocumentation1.7 k1715
Handler read rnd nextDocumentation2.9 G2913824556The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans.

Innodb buffer pool readsDocumentation29.8 k29759The number of logical reads that InnoDB could not satisfy from buffer pool and had to do a single-page read.
