Setting Maintenance Time
Overview
Maintenance time is a very important concept for Tencent Cloud Distributed Cache. To ensure the stability of your Tencent Cloud Distributed Cache instance, the backend system performs maintenance operations and troubleshooting on the instance during the maintenance time. To minimize the potential impact on your business, we recommend that you set an acceptable maintenance time for your business instance, usually during off-peak hours.
In addition, we also recommend you perform operations involving data migration during the maintenance time, such as instance version or architecture upgrade. Taking the database instance version upgrade as an example, as syncing the full and incremental data involves data migration, after the upgrade is completed, a momentary disconnection from the database may occur. When the upgrade is initiated, the Switch Time can be selected as During maintenance time, so that the instance version switch will be started during the next maintenance time after the data sync is completed. Note that when you select During maintenance time for Switch Time, the switch will not occur immediately after the database version upgrade is completed; instead, the sync will continue till the instance goes into the next maintenance time, during which the switch will be performed. Therefore, the overall time it takes to upgrade the instance may be longer.
Note:
Before maintenance is carried out for Tencent Cloud Distributed Cache, notifications will be sent to the contacts configured in your Tencent Cloud account via SMS and email.
