[REQUIRED]
The DB cluster identifier for the cluster being modified. This parameter is not case-sensitive.
Constraints:
The new DB cluster identifier for the DB cluster when renaming a DB cluster. This value is stored as a lowercase string.
Constraints:
Example: my-cluster2
A value that specifies whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the DB cluster. If this parameter is set to false , changes to the DB cluster are applied during the next maintenance window.
The ApplyImmediately parameter only affects NewDBClusterIdentifier values. If you set the ApplyImmediately parameter value to false, then changes to NewDBClusterIdentifier values are applied during the next maintenance window. All other changes are applied immediately, regardless of the value of the ApplyImmediately parameter.
Default: false
The number of days for which automated backups are retained. You must specify a minimum value of 1.
Default: 1
Constraints:
A list of VPC security groups that the DB cluster will belong to.
The port number on which the DB cluster accepts connections.
Constraints: Value must be 1150-65535
Default: The same port as the original DB cluster.
The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter.
The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Region.
Constraints:
hh24:mi-hh24:mi .The weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).
Format: ddd:hh24:mi-ddd:hh24:mi
The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Region, occurring on a random day of the week.
Valid Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun.
Constraints: Minimum 30-minute window.
True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.
Default: false
The configuration setting for the log types to be enabled for export to CloudWatch Logs for a specific DB cluster.
The list of log types to enable.
The list of log types to disable.
The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true.
For a list of valid engine versions, see Engine Releases for Amazon Neptune, or call DescribeDBEngineVersions.
A value that indicates whether upgrades between different major versions are allowed.
Constraints: You must set the allow-major-version-upgrade flag when providing an EngineVersion parameter that uses a different major version than the DB cluster's current version.
The name of the DB parameter group to apply to all instances of the DB cluster.
Note
When you apply a parameter group using DBInstanceParameterGroupName , parameter changes aren't applied during the next maintenance window but instead are applied immediately.
Default: The existing name setting
Constraints:
DBInstanceParameterGroupName parameter is only valid in combination with the AllowMajorVersionUpgrade parameter.true , tags are copied to any snapshot of the DB cluster that is created.Contains the scaling configuration of a Neptune Serverless DB cluster.
For more information, see Using Amazon Neptune Serverless in the Amazon Neptune User Guide .

Response Structure
(dict) --
DBCluster (dict) --
Contains the details of an Amazon Neptune DB cluster.
This data type is used as a response element in the DescribeDBClusters action.
AllocatedStorage (integer) --
AllocatedStoragealways returns 1, because Neptune DB cluster storage size is not fixed, but instead automatically adjusts as needed.
AvailabilityZones (list) --
Provides the list of EC2 Availability Zones that instances in the DB cluster can be created in.
BackupRetentionPeriod (integer) --
Specifies the number of days for which automatic DB snapshots are retained.
CharacterSetName (string) --
Not supported by Neptune.
DatabaseName (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.
DBClusterIdentifier (string) --
Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster.
DBClusterParameterGroup (string) --
Specifies the name of the DB cluster parameter group for the DB cluster.
DBSubnetGroup (string) --
Specifies information on the subnet group associated with the DB cluster, including the name, description, and subnets in the subnet group.
Status (string) --
Specifies the current state of this DB cluster.
PercentProgress (string) --
Specifies the progress of the operation as a percentage.
EarliestRestorableTime (datetime) --
Specifies the earliest time to which a database can be restored with point-in-time restore.
Endpoint (string) --
Specifies the connection endpoint for the primary instance of the DB cluster.
ReaderEndpoint (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.
MultiAZ (boolean) --
Specifies whether the DB cluster has instances in multiple Availability Zones.
Engine (string) --
Provides the name of the database engine to be used for this DB cluster.
EngineVersion (string) --
Indicates the database engine version.

ACTIVE - the IAM role ARN is associated with the DB cluster and can be used to access other Amazon services on your behalf.PENDING - the IAM role ARN is being associated with the DB cluster.INVALID - the IAM role ARN is associated with the DB cluster, but the DB cluster is unable to assume the IAM role in order to access other Amazon services on your behalf.FeatureName (string) --
The name of the feature associated with the Amazon Identity and Access Management (IAM) role. For the list of supported feature names, see DescribeDBEngineVersions.
