Instance Management
After creating a new instance, you can manage your Redis instances through the console, which includes operations such as capacity expansion, renewal, and instance management activities like monitoring and alerting.
The master-replica Redis console supports the following functionalities: creating slave libraries, configuring upgrades and downgrades, setting passwords, restart, slow query analysis, modifying configuration files, changing instance names, changing business groups, changing alarm templates, deleting, renewal and so forth.

master-replica Redis supports creating slave libraries. Click on the "Create slave Library" in the operation item of the master-replica Redis instance, and confirm the pop-up window of creating a slave library to complete the creation of the slave library. master-replica Redis supports up to 5 slave libraries.
Configuration Upgrade and Downgrade
Master-replica Redis supports self-expansion and downsizing of Redis instances. To change the capacity of an instance, click on "Configuration Upgrade and Downgrade" in the operation section of the instance on the console to expand or downsize the capacity, as follows:
Configuration upgrade and downgrade operations for master-replica Redis can be performed on the console. When expanding, if the host resources are sufficient and no data migration is required, Redis will not be affected at all. However, if host resources are insufficient during expansion and data migration is needed, you will be warned about the implications for Redis as follows: Redis services remain available during the upgrade and downgrade period, but the load will increase when data synchronization starts, and there will be a brief interruption of about 20 seconds during master-replica switching. Therefore, it is recommended to perform these operations during business off-peak times. For Redis downsizing, the entire process has no effect on Redis.
