可以看到2569事务开始后，能看到GTID_NEXT= ‘ce856f95-5aa9-11ea-87f4-0050569348f5:41‘，如果想跳过该事务错误，可以通过该GTID来实现，当然在正常生产环境下，如果错误不是很多，可以根据begin后面的具体语句来补充slave中缺失的数据

### UPDATE `ty`.`pritab`
### WHERE
###   @1=11 /* INT meta=0 nullable=0 is_null=0 */
###   @2=‘aaaaa‘ /* VARSTRING(300) meta=300 nullable=0 is_null=0 */
### SET
###   @1=11 /* INT meta=0 nullable=0 is_null=0 */
###   @2=‘cccc‘ /* VARSTRING(300) meta=300 nullable=0 is_null=0 */

可以知道，缺失的数据变是ty.pritab中id=11,name=‘aaaaa‘的数据，变更后未id=11,name=‘cccc‘，回插到从库

insert into ty.pritab values (11,‘cccc‘);

再通过pt-slave-restart跳过错误即可
