OMS allows you to download the configuration information of data synchronization projects and import project settings in batches. For more information, see Download and import the settings of synchronization objects.
View synchronization details
In the Synchronization Details section, you can view information about Schema Synchronization, Incremental Synchronization Log Pull, Full Synchronization, and Incremental Synchronization.
Schema Synchronization
Schema synchronization creates a topic. After a schema synchronization project is completed, you can query the new topic.
On the Schema Synchronization page, you can view the status, start time, end time, total duration, and progress of the schema synchronization project.
Incremental Synchronization Log Pulling
On the Incremental Synchronization Log Pulling page, you can view the status, start time, end time, total duration, and progress of log pulling for incremental synchronization.
Full Synchronization
A full synchronization migrates the existing data in the source database to the destination database. On the Full Synchronization page, you can view the status, start time, end time, total duration, and progress of a full synchronization project and the estimated total number of rows, completed number of rows, requests per second (RPS), and real-time traffic.
On the Full Synchronization Performance tab, you can view performance metrics in charts such as source RPS, destination RPS, synchronization traffic at the source and destination databases, average read time and sharding time at the source database, and average write time at the destination database. These metrics can help you identify performance issues effectively.
Incremental Synchronization
On the Incremental Synchronization page, you can view the status, latency, and the current timestamp of the incremental synchronization project. Based on this information, you can learn about the running status and performance of the data synchronization project.
When you create a data synchronization project, we recommend that you set the alert level and alert frequency to learn about the project running status in time. OMS provides low-level protection by default. You can modify the alert level based on your business requirements. For more information, see Alert settings.
When the incremental synchronization latency exceeds the specified alert threshold, the incremental synchronization project remains Running and the system does not trigger any alerts.
When the incremental synchronization latency is less than or equal to the specified alert threshold, the incremental synchronization status changes from Running to Monitoring. After the incremental synchronization status changes to Monitoring, it will not change back to Running when the latency exceeds the specified alert threshold.
The Incremental Synchronization Performance section displays the incremental synchronization information in real time. In the upper-right corner of the Incremental Synchronization Performance section, you can filter the incremental synchronization data of the last hour, last day, last week, or a custom period to view the changes in the synchronization performance in real time.
Parameter Description Latency The latency in synchronizing incremental data from the source database to the destination database, in seconds. Synchronization Traffic When incremental synchronization starts, the traffic may contain full-phase data traffic information. Average Write Duration The average write time during data synchronization. RPS The number of rows written to the destination database per second.
View the component monitoring metrics
On the details page of the data synchronization project, click View Component Monitoring in the upper-right corner to view information about the Store, Full-Import, and Incr-Sync components.
You can view the component ID, earliest pull timestamp, current pull timestamp, and status of the Store component. You can perform the following operations:
