Note: ApsaraDB for Redis is consistent with Redis in terms of product behavior. When a new instance is created, it generates database metadata which occupies a fraction of the instance’s storage space. The occupied space is shown on the ApsaraDB for Redis Console.
For master-slave instances, the generated database metadata occupies a space of about 32 MB.
For cluster instances, the generated database metadata occupies a space of about 32 MB multiplied by the number of nodes.
