报错信息
# mysqldump --default-character-set=utf8 --set-gtid-purged=on -uxx -pxx -hx.x.x.x --triggers --routines --events --single-transaction --databases xx >./bak_xx_$(date +%F).sql
mysqldump: [Warning] Using a password on the command line interface can be insecure.
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.
mysqldump: Couldn‘t execute ‘SAVEPOINT sp‘:
The MySQL server is running with the --transaction-write-set-extraction!=OFF option so it cannot execute this statement (1290)
2.处理方法
> set global transaction_write_set_extraction=off; --Reserved for future use.
Query OK, 0 rows affected (0.00 sec)
3.总结
数据库版本5.7.15 ，备份的时候报错，根据报错信息到官网查看相关参数含义。以上参数未来使用预留，默认是为Off，可以动态修改，未来组复制特性需要使用此参数。
