| database_name | core | string | Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster. |
| db_cluster_arn | core | string | The Amazon Resource Name (ARN) for the DB cluster. |
| db_cluster_identifier | core | string | Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster. |
| db_cluster_members | core | json | Provides the list of instances that make up the DB cluster. |
| db_cluster_option_group_memberships | core | json | Not supported by Neptune. |
| db_cluster_parameter_group | core | string | Specifies the name of the DB cluster parameter group for the DB cluster. |
| db_cluster_resource_id | core | string | The Amazon Region-unique, immutable identifier for the DB cluster. This identifier is found in Amazon CloudTrail log entries whenever the Amazon KMS key for the DB cluster is accessed. |
| db_subnet_group | core | string | Specifies information on the subnet group associated with the DB cluster, including the name, description, and subnets in the subnet group. |
| deletion_protection | core | bool | Indicates whether or not the DB cluster has deletion protection enabled. The database can't be deleted when deletion protection is enabled. |
| earliest_restorable_time | core | timestamp | Specifies the earliest time to which a database can be restored with point-in-time restore. |
| enabled_cloudwatch_logs_exports | core | array<string> | A list of the log types that this DB cluster is configured to export to CloudWatch Logs. Valid log types are: <code>audit</code> (to publish audit logs to CloudWatch) and slowquery (to publish slow-query logs to CloudWatch). See <a href="https://docs.aws.amazon.com/neptune/latest/userguide/cloudwatch-logs.html">Publishing Neptune logs to Amazon CloudWatch logs</a>. |
| endpoint | core | string | Specifies the connection endpoint for the primary instance of the DB cluster. |
| engine | core | string | Provides the name of the database engine to be used for this DB cluster. |
| engine_version | core | string | Indicates the database engine version. |
| global_cluster_identifier | core | string | Contains a user-supplied global database cluster identifier. This identifier is the unique key that identifies a global database. |
| hosted_zone_id | core | string | Specifies the ID that Amazon Route 53 assigns when you create a hosted zone. |
| iam_database_authentication_enabled | core | bool | True if mapping of Amazon Identity and Access Management (IAM) accounts to database accounts is enabled, and otherwise false. |
| io_optimized_next_allowed_modification_time | core | timestamp | The next time you can modify the DB cluster to use the <code>iopt1</code> storage type. |
| kms_key_id | core | string | If <code>StorageEncrypted</code> is true, the Amazon KMS key identifier for the encrypted DB cluster. |
| latest_restorable_time | core | timestamp | Specifies the latest time to which a database can be restored with point-in-time restore. |
| master_username | core | string | Not supported by Neptune. |
| multi_az | core | bool | Specifies whether the DB cluster has instances in multiple Availability Zones. |
| pending_modified_values | core | json | This data type is used as a response element in the <code>ModifyDBCluster</code> operation and contains changes that will be applied during the next maintenance window. |
| percent_progress | core | string | Specifies the progress of the operation as a percentage. |
| port | core | int64 | Specifies the port that the database engine is listening on. |
| preferred_backup_window | core | string | Specifies the daily time range during which automated backups are created if automated backups are enabled, as determined by the <code>BackupRetentionPeriod</code>. |
| preferred_maintenance_window | core | string | Specifies the weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC). |
| read_replica_identifiers | core | array<string> | Contains one or more identifiers of the Read Replicas associated with this DB cluster. |
| reader_endpoint | core | string | The reader endpoint for the DB cluster. The reader endpoint for a DB cluster load-balances connections across the Read Replicas that are available in a DB cluster. As clients request new connections to the reader endpoint, Neptune distributes the connection requests among the Read Replicas in the DB cluster. This functionality can help balance your read workload across multiple Read Replicas in your DB cluster. If a failover occurs, and the Read Replica that you are connected to is promoted to be the primary instance, your connection is dropped. To continue sending your read workload to other Read Replicas in the cluster, you can then reconnect to the reader endpoint. |
| replication_source_identifier | core | string | Not supported by Neptune. |
| serverless_v2_scaling_configuration | core | json | Shows the scaling configuration for a Neptune Serverless DB cluster. For more information, see <a href="https://docs.aws.amazon.com/neptune/latest/userguide/neptune-serverless-using.html">Using Amazon Neptune Serverless</a> in the <i>Amazon Neptune User Guide</i>. |
| status | core | string | Specifies the current state of this DB cluster. |
| storage_encrypted | core | bool | Specifies whether the DB cluster is encrypted. |
| storage_type | core | string | The storage type associated with the DB cluster. |
