ApsaraDB for Cassandra also provides common access control functions. For more information about how to create RAM users and grant permissions to the users, see Resource Access Management documentation. The following section describes related permission functions.

As with most other instance-type cloud services, ApsaraDB for Cassandra provides two built-in system permission policies:

  • AliyunCassandraReadOnlyAccess: grants read-only permissions on an ApsaraDB for Cassandra instance. RAM users with such permissions cannot perform O&M operations such as scaling up disks, scaling out nodes, enabling and disabling Internet access, and deleting clusters.
  • AliyunCassandraFullAccess: grants both read and write permissions on an ApsaraDB for Cassandra instance.addUserPer
