O&M and tuning of full and incremental synchronization tasks
A full and incremental synchronization task for full databases synchronizes the database and table schemas, historical data, and ongoing changes of a source database to a destination such as MaxCompute. This topic describes common O&M operations, troubleshooting methods, tuning recommendations, and alert configuration for these tasks.
This topic applies only to full and incremental synchronization tasks for full databases. For real-time incremental tasks, see Real-time full-database synchronization: Operations and tuning. For tasks that synchronize data only in scheduled batches, see O&M and tuning for offline database synchronization.
Choose Data Integration > Synchronization Task to open the synchronization task list. The task list shows the basic information and current running status of each task. You can filter tasks by task name, task status, creation time, data source type, and destination type.
Common changes to a full and incremental synchronization task for full databases include adding tables, removing tables, adjusting table mappings, adjusting resources, and modifying advanced parameters. To modify a task, choose More > Modify Configuration in the Operations column. After you make a change, submit the task and apply the update. The change takes effect only after you submit it.
Consider a rerun when destination data is corrupted, the real-time task has been failing for an extended period, source logs cannot be replayed, or the task must be initialized again. In the Operations column, choose More > Rerun to force a full and incremental re-initialization of all source tables.
