Setting Instance Maintenance Period
TencentDB for MongoDB allows you to adjust the instance maintenance period in the console to meet the changes in your business requirements.
Overview
The maintenance period is crucial for ensuring the stability of your TencentDB for MongoDB instance. During this period, the backend system performs necessary maintenance operations on your instance. To minimize the potential impact on your business, we recommend you set an acceptable maintenance period, preferably during off-peak hours. This will help mitigate any disruptions to your business operations.
In addition, we also recommend you perform operations involving data migration, such as adjusting the memory specification or AZ of mongod or mongos nodes, during the maintenance period. Taking the database instance AZ change as an example, as the full and incremental data needs to be synced from the original AZ to the new AZ, data migration will be involved. After the AZ is changed, a momentary disconnection from the database may occur. When the task is initiated, the Switch Time can be selected as During maintenance period, so that the instance data migration will be started during the next maintenance period after the data sync is completed.
Note:
Before maintenance is carried out for TencentDB for MongoDB, notifications will be sent to the contacts configured in your Tencent Cloud account through SMS and email.
