 The default value is `CLUSTER`, which means that the savemode is executed on the cluster. If you want to execute the savemode on the client,
 you can set it to `CLIENT`. Please use `CLUSTER` mode as much as possible, because when there are no problems with `CLUSTER` mode, we will remove `CLIENT` mode.
