根据提示信息我在MysqlReader中的jdbcUrl后添加了net_write_timeout参数，但是再次执行发现并没有什么效果，求助！！

Start with MysqlReader$Task.startRead and CommonRdbmsReader$Task.startRead, then trace the JDBC URL handling and the reported MySQL streaming exception. Compare the reader configuration with the connector behavior shown in the stack trace; done should be a reproducible diagnosis and a clearly verified resolution or documented limitation.
