Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed suppressed parts of the database.

If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make a complete dump, pass --all-databases --triggers --routines --events.

原因：

此参数会创建一个包含create table语句的table_name.sql文件，和包含数据的tb1_name.txt文件。

（1）cat t1.sql:

(2)t1.txt是数据文件，内容较大。
