While I run one-row-insert-sql or a-lot-rows-insert-sql(more than 1 second) in master, I execute SHOW FULL PROCESSLIST frequently in slave to catch the sql, but no sql is printed out.
And, the slow sql of slave sql thread is not logged in slow_query_log.
EXPLAIN is working well, but I doubt if the actual execution plan is different from EXPLAIN result.
