Could you please explain why in DM version 5.3, when migrating MySQL data to TiDB, if the upstream MySQL/MariaDB servers form a master-slave replication structure, the MySQL version needs to be higher than 5.7.1 or the MariaDB version needs to be equal to or higher than 10.1.3? If it is a single machine architecture, is MySQL version > 5.5 sufficient?

It is a bit strange. Are there any bugs with the master-slave setup in version 5.5?
