modify_global_cluster
(**kwargs)¶Modify a setting for an Amazon Aurora global cluster. You can change one or more database configuration parameters by specifying these parameters and the new values in the request. For more information on Amazon Aurora, see What is Amazon Aurora? in the Amazon Aurora User Guide .
Note
This action only applies to Aurora DB clusters.

Request Syntax
response = client.modify_global_cluster(
GlobalClusterIdentifier='string',
NewGlobalClusterIdentifier='string',
DeletionProtection=True|False,
EngineVersion='string',
AllowMajorVersionUpgrade=True|False
)
The DB cluster identifier for the global cluster being modified. This parameter isn't case-sensitive.
Constraints:
The new cluster identifier for the global database cluster when modifying a global database cluster. This value is stored as a lowercase string.
Constraints:
Example: my-cluster2
The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless ApplyImmediately
is enabled.
To list all of the available engine versions for aurora
(for MySQL 5.6-compatible Aurora), use the following command:
aws rds describe-db-engine-versions --engine aurora --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'
To list all of the available engine versions for aurora-mysql
(for MySQL 5.7-compatible and MySQL 8.0-compatible Aurora), 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
, use the following command:
aws rds describe-db-engine-versions --engine aurora-postgresql --query '*[]|[?SupportsGlobalDatabases == `true`].[EngineVersion]'
A value that indicates whether major version upgrades are allowed.
Constraints: You must allow major version upgrades when specifying 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. Apply any custom parameter groups after completing the upgrade.

Response Structure
(dict) --
GlobalCluster (dict) --
A data type representing an Aurora global database.
GlobalClusterIdentifier (string) --
Contains a user-supplied global database cluster identifier. This identifier is the unique key that identifies a global database cluster.
GlobalClusterResourceId (string) --
The Amazon Web Services Region-unique, immutable identifier for the global database cluster. This identifier is found in Amazon Web Services CloudTrail log entries whenever the Amazon Web Services KMS key for the DB cluster is accessed.
GlobalClusterArn (string) --
The Amazon Resource Name (ARN) for the global database cluster.
Status (string) --
Specifies the current state of this global database cluster.
Engine (string) --
The Aurora database engine used by the global database cluster.
EngineVersion (string) --
Indicates the database engine version.
DatabaseName (string) --
The default database name within the new global database cluster.
StorageEncrypted (boolean) --
The storage encryption setting for the global database cluster.
DeletionProtection (boolean) --
The deletion protection setting for the new global database cluster.
GlobalClusterMembers (list) --
The list of cluster IDs for secondary clusters within the global database cluster. Currently limited to 1 item.
(dict) --
A data structure with information about any primary and secondary clusters associated with an Aurora global database.
DBClusterArn (string) --
The Amazon Resource Name (ARN) for each Aurora cluster.
Readers (list) --
The Amazon Resource Name (ARN) for each read-only secondary cluster associated with the Aurora global database.
IsWriter (boolean) --
Specifies whether the Aurora cluster is the primary cluster (that is, has read-write capability) for the Aurora global database with which it is associated.
GlobalWriteForwardingStatus (string) --
Specifies whether a secondary cluster in an Aurora global database has write forwarding enabled, not enabled, or is in the process of enabling it.
FailoverState (dict) --
A data object containing all properties for the current state of an in-process or pending failover process for this Aurora global database. This object is empty unless the FailoverGlobalCluster API operation has been called on this Aurora global database ( GlobalCluster ).
Status (string) --
The current status of the Aurora global database ( GlobalCluster ). Possible values are as follows:
GlobalCluster
's primary DB cluster and the specified secondary DB cluster are being verified before the failover process can start.FromDbClusterArn (string) --
The Amazon Resource Name (ARN) of the Aurora DB cluster that is currently being demoted, and which is associated with this state.
ToDbClusterArn (string) --
The Amazon Resource Name (ARN) of the Aurora DB cluster that is currently being promoted, and which is associated with this state.
