BUG#23300: Slow query log on slave does not log slow replicated statements NOTE: this is the backport to next-mr. When using replication, the slave will not log any slow query logs queries replicated from the master, even if the option "--log-slow-slave-statements" is set and these take more than "log_query_time" to execute. In order to log slow queries in replicated thread one needs to set the --log-slow-slave-statements, so that the SQL thread is initialized with the correct switch. Although setting this flag correctly configures the slave thread option to log slow queries, there is an issue with the condition that is used to check whether to log the slow query or not. When replaying binlog events the statement contains the SET TIMESTAMP clause which will force the slow logging condition check to fail. Consequently, the slow query logging will not take place. This patch addresses this issue by removing the second condition from the log_slow_statements as it prevents slow queries to be binlogged and seems to be deprecated.
