The Basic Information section displays the basic information of the current data subscription task.
| Parameter | Description |
|---|---|
| Connection Details | Click Connection Details to view detailed information about the source cloud service provider, database type, instance type, and region of the data subscription task. |
| Task ID | The unique identifier of the data subscription task. |
| Subscription Type | The type of subscription selected when creating the data subscription task. |
| Billing Method | The current billing method is limited-time free. |
| Created At | The creation time of the current data subscription task. |
| Incremental Data Time Range | The timestamp range of incremental data stored in the data subscription task, indicating the time when incremental data was executed and written to the transaction log in the source database. |
| Write Data Timestamp Range | The timestamp range of incremental data in each partition of the data subscription task, which represents the current time when data is written to the partition. The data subscription task will periodically clean up partition data from 24 hours ago and update the timestamp range. Please consume the data in a timely manner to avoid data loss. |
| Write Data Offset Range | The consumption point (offset) range of incremental data in each partition of the data subscription task. |

View subscription details
The Subscription Details section displays the status of the precheck results and data subscription, the topic, topic partitioning strategy, endpoint, and subscription address for the current task.
Precheck
In the Precheck section, data subscription checks whether the data source connection and incremental synchronization log format meet the requirements. You can proceed to the next step only after all precheck tasks are completed. If an error occurs during precheck:
You can troubleshoot and fix the issue, then re-execute the precheck until it succeeds.
You can also view the error cause, confirm that it does not affect the data subscription task, and click Ignore or Remove in the Actions column of the failed precheck task.
Data Subscription
The Data Subscription page contains the Consumption Management and Performance Monitoring tabs.
On the Consumption Management tab, you can view information such as consumer group name, account, Client ID, and creation time, as well as details for each consumer group, including partition number, next consumption point, Client ID, write time to the partition, number of unconsumed records, and message delay.
You can modify the password or delete existing consumer groups.
Modify the password: Click ... in the Actions column of the target consumer group and select Modify Password. In the Modify Password dialog box, enter the new password and confirm it, then click Save.
To add a new consumer group, click Add Consumer Group in the upper-right corner of the Consumption Management tab. In the Add Consumer Group dialog box, configure the parameters and click Add.
Parameter Description Name Enter the name of the consumer group. The name must be 16 characters or fewer and can contain only digits, English letters, and underscores (_). Account Enter the account of the consumer group. The account must be 16 characters or fewer and can contain only digits, English letters, and underscores (_). Password Enter the password of the consumer group account. The password must be 8 to 32 characters long and contain at least two uppercase English letters, two lowercase English letters, two digits, and two special characters ( ~!@#$%^&*_-+=|\(){}[]:;,./?).Confirm Password Enter the password again for confirmation. Delete a consumer group: Click ... in the Actions column of the target consumer group and select Delete. In the confirmation dialog box that appears, click Delete.
Notice
- You cannot delete a consumer group that has active consumer connections.
- After a consumer group is deleted, the consumer program cannot connect to it. Proceed with caution.
On the Performance Monitoring tab, you can view the graphs of Incremental Data Write BPS, Incremental Data Write RPS, and Incremental Data Retrieval Latency to effectively identify performance-related issues. You can also filter the graphs by Last Hour, Last 2 Hours, Last Day, or custom time periods in the upper-right corner of the Performance Monitoring tab to view the changes in subscription performance in segments and in real time.
Parameter Description Incremental Data Write BPS The amount of incremental data written by the data subscription write task instance, measured in KB/s. Incremental Data Write RPS The number of records indicating changes in the amount of incremental data written by the data subscription write task instance. Incremental Data Fetch Delay The delay between the transaction commit time of the last record written to Kafka and the current time.
