Amazon Neptune

2022/06/08 - Amazon Neptune - 6 new3 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.

FailoverGlobalCluster (new) Link ¶

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.

CreateGlobalCluster (new) Link ¶

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.

string

param NewGlobalClusterIdentifier:

A new cluster identifier to assign to the global database. This value is stored as a lowercase string.

Constraints:

  • Must contain from 1 to 63 letters, numbers, or hyphens.

  • The first character must be a letter.

  • Can't end with a hyphen or contain two consecutive hyphens

param DeletionProtection:

Indicates whether the global database has deletion protection enabled. The global database cannot be deleted when deletion protection is enabled.

type EngineVersion:

string

param EngineVersion:

The version number of the database engine to which you want to upgrade. Changing this parameter will result in an outage. The change is applied during the next maintenance window unless ApplyImmediately is enabled.

type AllowMajorVersionUpgrade:

boolean

param AllowMajorVersionUpgrade:

A value that indicates whether major version upgrades are allowed.

Constraints: You must allow major version upgrades if you specify a value for the EngineVersion parameter that is a different major version than the DB cluster's current version.

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.

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.

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.

param DeletionProtection:

A value that indicates whether the DB cluster has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is enabled.

type GlobalClusterIdentifier:

string

param GlobalClusterIdentifier:

The ID of the Neptune global database to which this new DB cluster should be added.

rtype:

dict

      This data type is used as a response element in the DescribeDBClusters action.

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.
