In fact, with RBR there is a binlog event for each modified row, thus the mutex is acquired for every row.
row *************************** Id: 7929352 User: system user Host: db: NULL Command: Connect Time: 69899 State: invalidating query cache entries (table) Info: NULL replication shows Seconds_Behind_Master: 70429 Once the invalidating query cache entries (table) process has finished the slave catches up.
Rows: ~49,917,839 Inno DB latin1_swedish_ci Size: 28.7 Gi B I've now yet been able to repeat with 100% accuracy.
What I'm trying to determine is whether or not there is any benefit at all to allowing the query cache to be used for SELECT statements that are being run against these tables.
Since they get invalidated so quickly, it seems to me the best thing would be to just use SQL_NO_CACHE on SELECT statements with these tables.
It often happens to see and hear of replication SQL thread almost always in state “invalidating query cache entries (table)” .
While sometime this works, others don’t; the query cache is “disabled” and you still see the SQL thread in state “invalidating query cache entries (table)”.
