2022/06/08 - Amazon Neptune - 6 new 3 updated api methods
Changes This release adds support for Neptune to be configured as a global database, with a primary DB cluster in one region, and up to five secondary DB clusters in other regions.
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.
Note
This action applies only to Neptune global databases. This action is only intended for use on healthy Neptune global databases with healthy Neptune DB clusters and no region-wide outages, to test disaster recovery scenarios or to reconfigure the global database topology.

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.

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 .

boolean
Specifies whether the DB cluster is encrypted.
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.
If an encryption key is not specified in KmsKeyId :
If ReplicationSourceIdentifier identifies an encrypted source, then Amazon Neptune will use the encryption key used to encrypt the source. Otherwise, Amazon Neptune will use your default encryption key.
If the StorageEncrypted parameter is true and ReplicationSourceIdentifier is not specified, then Amazon Neptune will use your default encryption key.
Amazon KMS creates the default encryption key for your Amazon account. Your Amazon account has a different default encryption key for each Amazon Region.
If you create a Read Replica of an encrypted DB cluster in another Amazon Region, you must set KmsKeyId to a KMS key ID that is valid in the destination Amazon Region. This key is used to encrypt the Read Replica in that Amazon Region.

Default: false .

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) --
AllocatedStorage always 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.
(string) --
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.

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.
