How Do I Reduce the Capacity of a Cluster DCS Instance?
No. Capacity reduction is supported only for single-node and master/standby instances. The capacity of a Proxy Cluster or Redis Cluster instance can only be expanded, and cannot be reduced.
- If you want to use a smaller Proxy Cluster instance, back up the data of the existing instance, and create a new Proxy Cluster instance with the desired capacity. Then, import the backup data to the new instance. After the data migration is complete, delete the old instance. For details about data migration operations, see Importing Backup Files.
- If you want to use a smaller Redis Cluster instance, create a new Redis Cluster instance with the desired capacity, and migrate data online from the old instance to the new instance. After the migration is complete, delete the old instance. For details about data migration operations, see Migrating Data Online.
