Does DRS Support Resumable Uploads?¶
In database migration scenarios, if a migration task fails due to unavoidable problems (such as network fluctuation), DRS records the current parsing and replay point (which is the basis of database internal consistency) and then resumes data transfer from the point to ensure data integrity.
For incremental migration, DRS automatically retries for multiple times. For full migration of MySQL databases, the system automatically resumes the migration for three times by default. After the number of automatic retry failures reaches a specified value, the task becomes abnormal. You need to analyze the cause based on logs and try to rectify the blocking point (for example, the database password is changed). If the environment cannot be restored and the required logs have been eliminated, you can use the reset the task.
