Any chance to get mysql.GTIDSet after full dump ?

[jianhaiqing]

As you know, file-position will be stopped after master-slave switch, and it's hard to find the corresponding file-position of binlog after master-slave switch.
go-mysql-elasticsearch will exit after master-slave switch.
if mysql.GTIDSet can be recorded before mysqldump is emitted , we might have chances to continue binlog dump gtid .
Any idea ?

Is it possible to add "--set-gtid-purged=auto" for mysqldump, and try to parse

mysqldump output including gtid:
SET @@GLOBAL.GTID_PURGED='c0977f88-3104-11e9-81e1-00505690245b:1-274559';

gtidExp = regexp.MustCompile("SET @@GLOBAL.GTID_PURGED='(.+)';")

1. mysqldump should larger than 5.6

Any suggestion about this solution ?
