Changing the master
If a cluster consists of multiple hosts, you can make a replica of the master if necessary. It takes about two minutes on average to switch, and the cluster is available during that time.
To switch the master:
Management console
- Go to the folder page and select Managed Service for Redis.
- Select the appropriate cluster from the list.
- Open the Hosts tab.
- Click Switch master.
- In the window that opens, check I want to switch the master and click Switch.
