ApsaraDB for Redis is consistent with Redis in terms of product behavior. A newly created instance generates database metadata that occupies a fraction of the storage space on this instance. The ApsaraDB for Redis console displays the occupied space.

Notes:

  • For master-replica instances and single-node instances, the occupied space is approximately 32 MB.

  • For cluster instances, the occupied space is approximately 32 MB multiplied by the number of nodes in a cluster.
