Starting October 25, 2026, Database Autonomy Service (DAS) will change the database log delivery service from free to a commercial paid service, with a free transition period. This topic describes the background, effective time, impact scope, recommended actions, and FAQ of this adjustment.
Background information
The database log delivery service is a core capability of DAS. For a long time, it was not released as a standalone product and was invoked only as an underlying capability of the CloudLens series of Simple Log Service (SLS), such as CloudLens for Redis, CloudLens for RDS, and CloudLens for PolarDB. The service provides free real-time collection and downstream delivery (such as to SLS and OSS) of various logs, including SQL Explorer, audit logs, slow query logs, error logs, and runtime logs, and handles log delivery tasks for a large number of database instances.
As infrastructure costs continue to rise, we plan to change the database log delivery service from free to a commercial paid service to ensure its long-term stable operation and continuous iteration. After commercialization, the service will be provided as a standalone product. You can independently subscribe to, configure, and manage log delivery tasks through the Log Delivery feature in the DAS console, or continue to configure log delivery tasks in CloudLens. The two methods coexist and do not affect each other.
Effective time
00:00 on October 25, 2026 (Singapore Time).
Adjustment details
Starting from 00:00 on October 25, 2026 (Singapore Time), the database log delivery service changes from free to paid and is billed separately in DAS. When you use the feature, the storage, traffic, and computing fees generated by downstream services such as SLS and OSS are still billed separately by the corresponding services.
The DAS console will open the log delivery feature entry at the same time. The original CloudLens feature and entry are retained.
The period from the release of this notice to the effective time is a free transition period. During this period, the log delivery service remains available at no cost.
Impact scope
Affected users: All users who use the log delivery capability through the CloudLens series.
Affected feature: The DAS database log delivery service, which delivers various logs, including SQL Explorer, audit logs, slow query logs, error logs, and runtime logs.
Impact dimension | Description |
Billing method | The log delivery service changes from free to paid. No fees are incurred during the transition period. |
Usage | Existing delivery pipelines require no modification. The configuration method and user experience remain unchanged. |
Business continuity | Normal database operation is not affected. Delivery tasks continue to run without interruption, and no downstream data is lost. |
Recommended actions
Existing CloudLens users have automatically activated the log delivery service and do not need to take any action. After formal billing starts, simply pay attention to your DAS bills.
If you no longer need the delivery capability, close the corresponding delivery tasks through the CloudLens entry before the effective time. Historical data that has already been delivered is not affected.
Contact us
Before the effective date, we will send multiple rounds of notifications by email, text message, and console alerts.

FAQ
Q: Do the delivery tasks configured through the CloudLens entry and the "Log Delivery" entry in the DAS console conflict with or overwrite each other?
A: No. The delivery tasks from the two entries are initiated by different parties (the CloudLens side and the DAS side). They can be configured independently and do not affect, overwrite, or conflict with each other. The "Log Delivery" entry in the DAS console will open on October 25, 2026, and will support delivery to downstream systems such as SLS and OSS.
Q: Does this adjustment affect my business?
A: No. The delivery pipeline and usage remain unchanged, and normal database operation is not affected. Existing CloudLens users have already activated the service and need to take no action. Delivery tasks continue to run, and no downstream data is lost.
Q: Why is the service changing from free to paid?
A: As the number of registered instances continues to grow, infrastructure costs for log collection, cross-region transmission, real-time pipelines, and multi-replica reliability assurance keep rising. Commercialization ensures the long-term stable operation and continuous iteration of the service.
Q: Will I be charged twice by SLS or CloudLens?
A: No. This adjustment charges the DAS log delivery service fee. The storage, traffic, and computing fees of downstream SLS and OSS are billed separately by the corresponding services. They are different upstream and downstream services, so no duplicate charges apply.
Q: What if I no longer want to use the paid log delivery service?
A: Close the corresponding delivery tasks through the CloudLens entry. After you close them, no delivery service fees are incurred. Historical data that has already been delivered is retained, and downstream storage fees are charged separately according to the rules of the corresponding service.
