If you no longer need a CKafka instance, you can terminate and release it.
The lifecycle of a CKafka instance refers to all statuses from the start of the instance to its release. Properly managing an instance in different statuses can ensure that applications running on it can provide services economically and efficiently. The statuses of an instance are as follows:
Status
Status Attribute
Description
Creating
Intermediate status
The instance has been created but is not running yet.
Running
Stable status
The instance is running normally, and the disk space, traffic, and the number of connections are all within the normal range.
Deleting
Intermediate status
The instance is being deleted through the console or API.
Isolated
Intermediate status
The instance is isolated through the console or API, or it is in a seven-day isolation status due to overdue payments.
Failed to create
Intermediate status
You have purchased an instance through the console or API but are not assigned the instance. In this case, submit a ticket.
Failed to delete
Stable status
CKafka fails to release resources after the instance is manually deleted or is not renewed 14 days after expiration (including the 14th day).
Directions
Manual termination
You can manually terminate a monthly-subscribed instance before it expires by following the steps below:
2. On the instance list page, click More > Terminate/Return in the Operation column.
3. In the pop-up window, click Submit to terminate the instance.
Note:
After a monthly subscribed instance is terminated, it will be in “Isolated” status for seven days in the CKafka console.
Isolated instances cannot produce or consume data. Data and configurations saved in CKafka will not be terminated, but expired messages will still be automatically deleted according to the open-source Kafka mechanism.
For instances in the seven-day isolation status, you can go to the CKafka console to renew them by clicking Renew in the Operation column on the instance list page. Successfully renewed instances can go back to the running status and be normally used.
Automatic termination upon expiration/overdue payment
Monthly-subscribed instances can be retained in the CKafka console for up to seven natural days after they expire or have overdue payments. You can continue to use them if you renew them within 7 days after expiration. For details, see Payment Overdue.
If the CKafka instance is not renewed within 7 (inclusive) days after expiration, its resources will be released within 24 hours after expiration, and data will be cleared and cannot be restored.
Deleting instances
A monthly-subscribed instance will be retained for seven days in the CKafka console after manual termination or automatic termination upon expiration/overdue payment, during which it will be in “Isolated” status. After 7 (inclusive) days, it will be completely released, and you can delete it completely.
Note:
After deletion, all data will be cleared and cannot be recovered. Please back up the data in advance.
