2024/09/16 - Amazon Relational Database Service - 7 updated api methods
Changes Launching Global Cluster tagging.
{'Tags': [{'Key': 'string', 'Value': 'string'}]}
Response {'GlobalCluster': {'TagList': [{'Key': 'string', 'Value': 'string'}]}}
Creates an Aurora global database spread across multiple Amazon Web Services Regions. The global database contains a single primary cluster with read-write capability, and a read-only secondary cluster that receives data from the primary cluster through high-speed replication performed by the Aurora storage subsystem.
You can create a global database that is initially empty, and then create the primary and secondary DB clusters in the global database. Or you can specify an existing Aurora cluster during the create operation, and this cluster becomes the primary cluster of the global database.

string
The cluster identifier for this global database cluster. This parameter is stored as a lowercase string.
string
The Amazon Resource Name (ARN) to use as the primary cluster of the global database.
If you provide a value for this parameter, don't specify values for the following settings because Amazon Aurora uses the values from the specified source DB cluster:
DatabaseName
Engine
EngineVersion
StorageEncrypted
string
The database engine to use for this global database cluster.
Valid Values: aurora-mysql | aurora-postgresql
Constraints:
Can't be specified if SourceDBClusterIdentifier is specified. In this case, Amazon Aurora uses the engine of the source DB cluster.
string
The engine version to use for this global database cluster.
Constraints:
Can't be specified if SourceDBClusterIdentifier is specified. In this case, Amazon Aurora uses the engine version of the source DB cluster.
string
The life cycle type for this global database cluster.
This setting only applies to Aurora PostgreSQL-based global databases.
You can use this setting to enroll your global cluster into Amazon RDS Extended Support. With RDS Extended Support, you can run the selected major engine version on your global cluster past the end of standard support for that engine version. For more information, see Using Amazon RDS Extended Support in the Amazon Aurora User Guide.
Valid Values: open-source-rds-extended-support | open-source-rds-extended-support-disabled
Default: open-source-rds-extended-support
boolean
Specifies whether to enable deletion protection for the new global database cluster. The global database can't be deleted when deletion protection is enabled.
string
The name for your database of up to 64 alphanumeric characters. If you don't specify a name, Amazon Aurora doesn't create a database in the global database cluster.
Constraints:
Can't be specified if SourceDBClusterIdentifier is specified. In this case, Amazon Aurora uses the database name from the source DB cluster.
boolean
Specifies whether to enable storage encryption for the new global database cluster.
Constraints:
Can't be specified if SourceDBClusterIdentifier is specified. In this case, Amazon Aurora uses the setting from the source DB cluster.

{'GlobalCluster': {'TagList': [{'Key': 'string', 'Value': 'string'}]}}
Promotes the specified secondary DB cluster to be the primary DB cluster in the global database cluster to fail over or switch over a global database. Switchover operations were previously called "managed planned failovers."
How you use this operation depends on whether you are failing over or switching over your global database cluster:
Failing over - Specify the AllowDataLoss parameter and don't specify the Switchover parameter.
Switching over - Specify the Switchover parameter or omit it, but don't specify the AllowDataLoss parameter.
About failing over and switching over
While failing over and switching over a global database cluster both change the primary DB cluster, you use these operations for different reasons:
Failing over - Use this operation to respond to an unplanned event, such as a Regional disaster in the primary Region. Failing over can result in a loss of write transaction data that wasn't replicated to the chosen secondary before the failover event occurred. However, the recovery process that promotes a DB instance on the chosen seconday DB cluster to be the primary writer DB instance guarantees that the data is in a transactionally consistent state. For more information about failing over an Amazon Aurora global database, see Performing managed failovers for Aurora global databases in the Amazon Aurora User Guide.
Switching over - Use this operation on a healthy global database cluster for planned events, such as Regional rotation or to fail back to the original primary DB cluster after a failover operation. With this operation, there is no data loss. For more information about switching over an Amazon Aurora global database, see Performing switchovers for Aurora global databases in the Amazon Aurora User Guide.

string
[REQUIRED]
The identifier of the global database cluster (Aurora global database) this operation should apply to. The identifier is the unique key assigned by the user when the Aurora global database is created. In other words, it's the name of the Aurora global database.
Constraints:
Must match the identifier of an existing global database cluster.
string
[REQUIRED]
The identifier of the secondary Aurora DB cluster that you want to promote to the primary for the global database cluster. Use the Amazon Resource Name (ARN) for the identifier so that Aurora can locate the cluster in its Amazon Web Services Region.
boolean
Specifies whether to allow data loss for this global database cluster operation. Allowing data loss triggers a global failover operation.
If you don't specify AllowDataLoss, the global database cluster operation defaults to a switchover.
Constraints:
Can't be specified together with the Switchover parameter.
boolean
Specifies whether to switch over this global database cluster.

Can't be specified together with the AllowDataLoss parameter.

Request Syntax
client.modify_global_cluster(
GlobalClusterIdentifier='string',
NewGlobalClusterIdentifier='string',
DeletionProtection=True|False,
EngineVersion='string',
AllowMajorVersionUpgrade=True|False
)
string
The cluster identifier for the global cluster to modify. This parameter isn't case-sensitive.
Constraints:
Must match the identifier of an existing global database cluster.
string
The new cluster identifier for the global database cluster. 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.
Example: my-cluster2
boolean
Specifies whether to enable deletion protection for the global database cluster. The global database cluster can't be deleted when deletion protection is enabled.
string
The version number of the database engine to which you want to upgrade.
To list all of the available engine versions for aurora-mysql (for MySQL-based Aurora global databases), use the following command:
aws rds describe-db-engine-versions --engine aurora-mysql --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'
To list all of the available engine versions for aurora-postgresql (for PostgreSQL-based Aurora global databases), use the following command:
aws rds describe-db-engine-versions --engine aurora-postgresql --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'
boolean
Specifies whether to allow major version upgrades.
Constraints: Must be enabled if you specify a value for the EngineVersion parameter that's a different major version than the global 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. Apply any custom parameter groups after completing the upgrade.

{'GlobalCluster': {'TagList': [{'Key': 'string', 'Value': 'string'}]}}
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."
Aurora 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 orginal replication topology. All secondary clusters are synchronized with the primary at the beginning of the process so the new primary continues operations for the Aurora 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. For more information about switching over an Aurora global database, see Performing switchovers for Amazon Aurora global databases in the Amazon Aurora User Guide.
