Changes Update rds client to latest version
Initiates the failover process for an Aurora global database ( GlobalCluster).
A failover for an Aurora 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) DB cluster are switched. The selected secondary DB cluster assumes full read/write capabilities for the Aurora global database.
For more information about failing over an Amazon Aurora global database, see Managed planned failover for Amazon Aurora global databases in the Amazon Aurora User Guide.

Request Syntax
client.failover_global_cluster(
GlobalClusterIdentifier='string',
TargetDbClusterIdentifier='string'
)
string
[REQUIRED]
Identifier of the Aurora global database ( GlobalCluster) that should be failed over. The identifier is the unique key assigned by the user when the Aurora global database was created. In other words, it's the name of the Aurora global database that you want to fail over.
Constraints:
Must match the identifier of an existing GlobalCluster (Aurora global database).
string
[REQUIRED]
Identifier of the secondary Aurora DB cluster that you want to promote to primary for the Aurora global database ( GlobalCluster.) Use the Amazon Resource Name (ARN) for the identifier so that Aurora can locate the cluster in its AWS Region.

'ToDbClusterArn': 'string'}}}
Creates an Aurora global database spread across multiple AWS 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 add a primary cluster and a secondary cluster to it. Or you can specify an existing Aurora cluster during the create operation, and this cluster becomes the primary cluster of the global database.
