 ### max_open_conn
 The maximum number of open connections to the database.
 
+### conn_max_lifetime
+
+Sets the maximum amount of time a connection may be reused. The default is 14400 (which means 14400 seconds or 4 hours). For MySQL, this setting should be shorter than the [`wait_timeout`](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_wait_timeout) variable.
