2026/06/11 - Amazon Neptune - 19 updated api methods
Changes Amazon Neptune now supports IPv6 dual-stack networking. You can create and manage Neptune DB clusters accessible over both IPv4 and IPv6 by specifying NetworkType as DUAL in CreateDBCluster, ModifyDBCluster, RestoreDBClusterFromSnapshot, and RestoreDBClusterToPointInTime API operations
{'NetworkType': 'string'}
Response {'DBCluster': {'NetworkType': 'string',
'PendingModifiedValues': {'NetworkType': 'string'}}}
Creates a new Amazon Neptune DB cluster.
You can use the ReplicationSourceIdentifier parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance.
Note that when you create a new cluster using CreateDBCluster directly, deletion protection is disabled by default (when you create a new production cluster in the console, deletion protection is enabled by default). You can only delete a DB cluster if its DeletionProtection field is set to false.

string
The Amazon KMS key identifier for an encrypted DB cluster.
The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB cluster with the same Amazon account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.

The DeleteDBInstance action deletes a previously provisioned DB instance. When you delete a DB instance, all automated backups for that instance are deleted and can't be recovered. Manual DB snapshots of the DB instance to be deleted by DeleteDBInstance are not deleted.
If you request a final DB snapshot the status of the Amazon Neptune DB instance is deleting until the DB snapshot is created. The API action DescribeDBInstance is used to monitor the status of this operation. The action can't be canceled or reverted once submitted.
Note that when a DB instance is in a failure state and has a status of failed, incompatible-restore, or incompatible-network, you can only delete it when the SkipFinalSnapshot parameter is set to true.
You can't delete a DB instance if it is the only instance in the DB cluster, or if it has deletion protection enabled.

{'DBCluster': {'NetworkType': 'string',
'PendingModifiedValues': {'NetworkType': 'string'}}}
Forces a failover for a DB cluster.
A failover for a DB cluster promotes one of the Read Replicas (read-only instances) in the DB cluster to be the primary instance (the cluster writer).
Amazon Neptune will automatically fail over to a Read Replica, if one exists, when the primary instance fails. You can force a failover when you want to simulate a failure of a primary instance for testing. Because each instance in a DB cluster has its own endpoint address, you will need to clean up and re-establish any existing connections that use those endpoint addresses when the failover is complete.

Default: false
string
Not supported by Neptune.
string
The name of the DB parameter group to apply to the DB instance. Changing this setting doesn't result in an outage. The parameter group name itself is changed immediately, but the actual parameter changes are not applied until you reboot the instance without failover. The db instance will NOT be rebooted automatically and the parameter changes will NOT be applied during the next maintenance window.
Default: Uses existing setting
Constraints: The DB parameter group must be in the same DB parameter group family as this DB instance.
integer
Not applicable. The retention period for automated backups is managed by the DB cluster. For more information, see ModifyDBCluster.

Must be in Universal Time Coordinated (UTC)
Must not conflict with the preferred maintenance window
Must be at least 30 minutes
string
The weekly time range (in UTC) during which system maintenance can occur, which might result in an outage. Changing this parameter doesn't result in an outage, except in the following situation, and the change is asynchronously applied as soon as possible. If there are pending actions that cause a reboot, and the maintenance window is changed to include the current time, then changing this parameter will cause a reboot of the DB instance. If moving this window to the current time, there must be at least 30 minutes between the current time and end of the window to ensure pending changes are applied.
Default: Uses existing setting
Format: ddd:hh24:mi-ddd:hh24:mi
Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun
Constraints: Must be at least 30 minutes
boolean
Specifies if the DB instance is a Multi-AZ deployment. Changing this parameter doesn't result in an outage and the change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true for this request.
string
The version number of the database engine to upgrade to. Currently, setting this parameter has no effect. To upgrade your database engine to the most recent release, use the ApplyPendingMaintenanceAction API.
boolean
Indicates that major version upgrades are allowed. Changing this parameter doesn't result in an outage and the change is asynchronously applied as soon as possible.
boolean
Indicates that minor version upgrades are applied automatically to the DB instance during the maintenance window. Changing this parameter doesn't result in an outage except in the following case and the change is asynchronously applied as soon as possible. An outage will result if this parameter is set to true during the maintenance window, and a newer minor version is available, and Neptune has enabled auto patching for that engine version.
string
Not supported by Neptune.

Your database will restart when you change the DBPortNumber value regardless of the value of the ApplyImmediately parameter.
Default: 8182
boolean
Indicates whether the DB instance is publicly accessible.
When the DB instance is publicly accessible and you connect from outside of the DB instance's virtual private cloud (VPC), its Domain Name System (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB instance, the endpoint resolves to the private IP address. Access to the DB instance is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB cluster doesn't permit it.
When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.
string
The ARN for the IAM role that permits Neptune to send enhanced monitoring metrics to Amazon CloudWatch Logs. For example, arn:aws:iam:123456789012:role/emaccess.
