Handler read first	11.9 k 11908	The number of times the first entry was read from an index. If this is high, it suggests that the server is doing a lot of full index scans; for example, SELECT col1 FROM foo, assuming that col1 is indexed.
Handler read key	778.9 k 778925	The number of requests to read a row based on a key. If this is high, it is a good indication that your queries and tables are properly indexed.
Handler read last	0 0

Handler read retry	0 0
Handler read rnd	227 k 227023	The 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 deleted	9.4 k 9385
Handler read rnd next	8.4 M 8360598	The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.

Handler mrr init

Handler mrr key refills

Handler mrr rowid refills

Handler read retry

Handler read rnd

227 k

The 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 deleted

9.4 k

Handler read rnd next

8.4 M

The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.
