Schedule maintenance operations — configuration changes, version upgrades, and restarts — for your Tair (Redis OSS-compatible) instance to run during off-peak hours by setting a maintenance window.
How it works
Alibaba Cloud performs periodic maintenance on Tair instances to ensure stability. On days when maintenance is scheduled, the instance enters the Maintaining Instance state some time before the maintenance window starts.
During the Maintaining Instance state:
Read access and data queries to the database remain available, including performance monitoring queries.
Instance configuration changes through the console are temporarily unavailable.
When the maintenance window begins, transient connections may occur. Set the maintenance window to a low-traffic period — for example, 02:00–04:00 — to minimize the impact on your application.
Before the maintenance window starts, Alibaba Cloud sends notifications by text message and email to the contacts associated with your account.
The console displays times in your local time zone.
Instances may temporarily disconnect when you make changes to them. For example, an instance is disconnected when you change its configurations. To minimize the impact on your business, we recommend that you perform these operations during the maintenance window.
Transient connections may occur after the maintenance window starts. Set the window to off-peak hours to reduce the impact on running applications.
