Amazon Relational Database Service

2024/10/22 - Amazon Relational Database Service - 7 updated api methods

Changes  Global clusters now expose the Endpoint attribute as one of its fields. It is a Read/Write endpoint for the global cluster which resolves to the Global Cluster writer instance.

CreateGlobalCluster (updated) Link ¶
Changes (response)
{'GlobalCluster': {'Endpoint': '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.

Note

This operation applies only to Aurora DB clusters.

Request Syntax

client.create_global_cluster(
    GlobalClusterIdentifier='string',
    SourceDBClusterIdentifier='string',
    Engine='string',
    EngineVersion='string',
    EngineLifecycleSupport='string',
    DeletionProtection=True|False,
    DatabaseName='string',
    StorageEncrypted=True|False,
    Tags=[
        {
            'Key': 'string',
            'Value': 'string'
        },
    ]
)
type GlobalClusterIdentifier

string

param GlobalClusterIdentifier

The cluster identifier for this global database cluster. This parameter is stored as a lowercase string.

type SourceDBClusterIdentifier

string

param SourceDBClusterIdentifier

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

type Engine

string

param Engine

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.

type EngineVersion

string

param EngineVersion

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.

type EngineLifecycleSupport

string

param EngineLifecycleSupport

The life cycle type for this global database cluster.

Note

By default, this value is set to open-source-rds-extended-support , which enrolls your global cluster into Amazon RDS Extended Support. At the end of standard support, you can avoid charges for Extended Support by setting the value to open-source-rds-extended-support-disabled . In this case, creating the global cluster will fail if the DB major version is past its end of standard support date.

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

type DeletionProtection

boolean

param DeletionProtection

Specifies whether to enable deletion protection for the new global database cluster. The global database can't be deleted when deletion protection is enabled.

type DatabaseName

string

param DatabaseName

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.

type StorageEncrypted

boolean

param StorageEncrypted

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.

type Tags

list

param Tags

Tags to assign to the global cluster.

  • (dict) --

    Metadata assigned to an Amazon RDS resource consisting of a key-value pair.

    For more information, see Tagging Amazon RDS resources in the Amazon RDS User Guide or Tagging Amazon Aurora and Amazon RDS resources in the Amazon Aurora User Guide .

    • Key (string) --

      A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', ':', '/', '=', '+', '-', '@' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$").

    • Value (string) --

      A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain only the set of Unicode letters, digits, white-space, '_', '.', ':', '/', '=', '+', '-', '@' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$").

FailoverGlobalCluster (updated) Link ¶
Changes (response)
{'GlobalCluster': {'Endpoint': '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."

Note

Although this operation can be used either to fail over or to switch over a global database cluster, its intended use is for global database failover. To switch over a global database cluster, we recommend that you use the SwitchoverGlobalCluster operation instead.

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 .

SwitchoverGlobalCluster (updated) Link ¶
Changes (response)
{'GlobalCluster': {'Endpoint': '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 .

Note

This operation is intended for controlled environments, for operations such as "regional rotation" or to fall back to the original primary after a global database failover.
