2025/05/16 - Amazon Neptune - 1 new 6 updated api methods
Changes This release adds Global Cluster Switchover capability which enables you to change your global cluster's primary AWS Region, the region that serves writes, while preserving the replication between all regions in the global cluster.
Switches over the specified secondary DB cluster to be the new primary DB cluster in the global database cluster. Switchover operations were previously called "managed planned failovers."
Promotes the specified secondary cluster to assume full read/write capabilities and demotes the current primary cluster to a secondary (read-only) cluster, maintaining the original replication topology. All secondary clusters are synchronized with the primary at the beginning of the process so the new primary continues operations for the global database without losing any data. Your database is unavailable for a short time while the primary and selected secondary clusters are assuming their new roles.

Creates a Neptune global database spread across multiple Amazon Regions. The global database contains a single primary cluster with read-write capability, and read-only secondary clusters that receive data from the primary cluster through high-speed replication performed by the Neptune storage subsystem.
You can create a global database that is initially empty, and then add a primary cluster and secondary clusters to it, or you can specify an existing Neptune cluster during the create operation to become the primary cluster of the global database.

Response {'GlobalCluster': {'FailoverState': {'FromDbClusterArn': 'string',
'IsDataLossAllowed': 'boolean',
'Status': 'pending | failing-over | '
'cancelling',
'ToDbClusterArn': 'string'}}}
Initiates the failover process for a Neptune global database.
A failover for a Neptune global database promotes one of secondary read-only DB clusters to be the primary DB cluster and demotes the primary DB cluster to being a secondary (read-only) DB cluster. In other words, the role of the current primary DB cluster and the selected target secondary DB cluster are switched. The selected secondary DB cluster assumes full read/write capabilities for the Neptune global database.

If you upgrade the major version of a global database, the cluster and DB instance parameter groups are set to the default parameter groups for the new version, so you will need to apply any custom parameter groups after completing the upgrade.

The Amazon Resource Name (ARN) of the Neptune DB cluster that is currently being promoted, and which is associated with this state.
IsDataLossAllowed (boolean) --
Indicates whether the operation is a global switchover or a global failover. If data loss is allowed, then the operation is a global failover. Otherwise, it's a switchover.
{'GlobalCluster': {'FailoverState': {'FromDbClusterArn': 'string',
'IsDataLossAllowed': 'boolean',
'Status': 'pending | failing-over | '
'cancelling',
'ToDbClusterArn': 'string'}}}
Detaches a Neptune DB cluster from a Neptune global database. A secondary cluster becomes a normal standalone cluster with read-write capability instead of being read-only, and no longer receives data from a the primary cluster.

Response Structure
(dict) --
GlobalCluster (dict) --
Contains the details of an Amazon Neptune global database.
This data type is used as a response element for the CreateGlobalCluster, DescribeGlobalClusters, ModifyGlobalCluster, DeleteGlobalCluster, FailoverGlobalCluster, and RemoveFromGlobalCluster actions.
GlobalClusterIdentifier (string) --
Contains a user-supplied global database cluster identifier. This identifier is the unique key that identifies a global database.
GlobalClusterResourceId (string) --
An immutable identifier for the global database that is unique within in all regions. This identifier is found in CloudTrail log entries whenever the KMS key for the DB cluster is accessed.
GlobalClusterArn (string) --
The Amazon Resource Name (ARN) for the global database.
Status (string) --
Specifies the current state of this global database.
Engine (string) --
The Neptune database engine used by the global database ( "neptune").
EngineVersion (string) --
The Neptune engine version used by the global database.
StorageEncrypted (boolean) --
The storage encryption setting for the global database.
DeletionProtection (boolean) --
The deletion protection setting for the global database.
GlobalClusterMembers (list) --
A list of cluster ARNs and instance ARNs for all the DB clusters that are part of the global database.
(dict) --
A data structure with information about any primary and secondary clusters associated with an Neptune global database.
DBClusterArn (string) --
The Amazon Resource Name (ARN) for each Neptune cluster.
Readers (list) --
The Amazon Resource Name (ARN) for each read-only secondary cluster associated with the Neptune global database.
(string) --
IsWriter (boolean) --
Specifies whether the Neptune cluster is the primary cluster (that is, has read-write capability) for the Neptune global database with which it is associated.
FailoverState (dict) --
A data object containing all properties for the current state of an in-process or pending switchover or failover process for this global cluster (Neptune global database). This object is empty unless the SwitchoverGlobalCluster or FailoverGlobalCluster operation was called on this global cluster.
Status (string) --
The current status of the global cluster. Possible values are as follows:
pending – The service received a request to switch over or fail over the global cluster. The global cluster's primary DB cluster and the specified secondary DB cluster are being verified before the operation starts.
failing-over – Neptune is promoting the chosen secondary Neptune DB cluster to become the new primary DB cluster to fail over the global cluster.
cancelling – The request to switch over or fail over the global cluster was cancelled and the primary Neptune DB cluster and the selected secondary Neptune DB cluster are returning to their previous states.
switching-over – This status covers the range of Neptune internal operations that take place during the switchover process, such as demoting the primary Neptune DB cluster, promoting the secondary Neptune DB cluster, and synchronizing replicas.
FromDbClusterArn (string) --
The Amazon Resource Name (ARN) of the Neptune DB cluster that is currently being demoted, and which is associated with this state.
ToDbClusterArn (string) --
The Amazon Resource Name (ARN) of the Neptune DB cluster that is currently being promoted, and which is associated with this state.
IsDataLossAllowed (boolean) --
Indicates whether the operation is a global switchover or a global failover. If data loss is allowed, then the operation is a global failover. Otherwise, it's a switchover.
