    Valid Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun.

    Constraints: Minimum 30-minute window.

  • :replication_source_identifier (String)

    The Amazon Resource Name (ARN) of the source DB instance or DB cluster if this DB cluster is created as a read replica.

  • :tags (Array<Types::Tag>)

    Tags to assign to the DB cluster.

  • :storage_encrypted (Boolean)

    A value that indicates whether the DB cluster is encrypted.

  • :kms_key_id (String)

    The AWS 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 AWS 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 isn't specified in KmsKeyId:

    • If ReplicationSourceIdentifier identifies an encrypted source, then Amazon RDS will use the encryption key used to encrypt the source. Otherwise, Amazon RDS will use your default encryption key.

    • If the StorageEncrypted parameter is enabled and ReplicationSourceIdentifier isn't specified, then Amazon RDS will use your default encryption key.

    AWS KMS creates the default encryption key for your AWS account. Your AWS account has a different default encryption key for each AWS Region.

    If you create a read replica of an encrypted DB cluster in another AWS Region, you must set KmsKeyId to a KMS key ID that is valid in the destination AWS Region. This key is used to encrypt the read replica in that AWS Region.

  • :pre_signed_url (String)

    A URL that contains a Signature Version 4 signed request for the CreateDBCluster action to be called in the source AWS Region where the DB cluster is replicated from. You only need to specify PreSignedUrl when you are performing cross-region replication from an encrypted DB cluster.

    The pre-signed URL must be a valid request for the CreateDBCluster API action that can be executed in the source AWS Region that contains the encrypted DB cluster to be copied.

    The pre-signed URL request must contain the following parameter values:

    • KmsKeyId - The AWS KMS key identifier for the key to use to encrypt the copy of the DB cluster in the destination AWS Region. This should refer to the same KMS key for both the CreateDBCluster action that is called in the destination AWS Region, and the action contained in the pre-signed URL.

    • DestinationRegion - The name of the AWS Region that Aurora read replica will be created in.

    • ReplicationSourceIdentifier - The DB cluster identifier for the encrypted DB cluster to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are copying an encrypted DB cluster from the us-west-2 AWS Region, then your ReplicationSourceIdentifier would look like Example: arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1.

    To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.

    If you are using an AWS SDK tool or the AWS CLI, you can specify SourceRegion (or --source-region for the AWS CLI) instead of specifying PreSignedUrl manually. Specifying SourceRegion autogenerates a pre-signed URL that is a valid request for the operation that can be executed in the source AWS Region.

  • :enable_iam_database_authentication (Boolean)

    A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled.

    For more information, see IAM Database Authentication in the Amazon Aurora User Guide.

  • :backtrack_window (Integer)

    The target backtrack window, in seconds. To disable backtracking, set this value to 0.

    Currently, Backtrack is only supported for Aurora MySQL DB clusters.

    Default: 0

    Constraints:

    • If specified, this value must be set to a number from 0 to 259,200 (72 hours).

    ^

  • :enable_cloudwatch_logs_exports (Array<String>)

    The list of log types that need to be enabled for exporting to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon Aurora User Guide.

    Aurora MySQL

    Possible values are audit, error, general, and slowquery.

    Aurora PostgreSQL

    Possible values are postgresql and upgrade.

  • :engine_mode (String)

    The DB engine mode of the DB cluster, either provisioned serverless, parallelquery, global, or multimaster.

    The parallelquery engine mode isn't required for Aurora MySQL version 1.23 and higher 1.x versions, and version 2.09 and higher 2.x versions.

    The global engine mode isn't required for Aurora MySQL version 1.22 and higher 1.x versions, and global engine mode isn't required for any 2.x versions.

    The multimaster engine mode only applies for DB clusters created with Aurora MySQL version 5.6.10a.

    For Aurora PostgreSQL, the global engine mode isn't required, and both the parallelquery and the multimaster engine modes currently aren't supported.

    Limitations and requirements apply to some DB engine modes. For more information, see the following sections in the Amazon Aurora User Guide:

  • :scaling_configuration (Types::ScalingConfiguration)

    For DB clusters in serverless DB engine mode, the scaling properties of the DB cluster.

  • :deletion_protection (Boolean)

    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 disabled.

  • :global_cluster_identifier (String)

    The global cluster ID of an Aurora cluster that becomes the primary cluster in the new global database cluster.

  • :enable_http_endpoint (Boolean)

    A value that indicates whether to enable the HTTP endpoint for an Aurora Serverless DB cluster. By default, the HTTP endpoint is disabled.

    When enabled, the HTTP endpoint provides a connectionless web service API for running SQL queries on the Aurora Serverless DB cluster. You can also query your database from inside the RDS console with the query editor.

    For more information, see Using the Data API for Aurora Serverless in the Amazon Aurora User Guide.

  • :copy_tags_to_snapshot (Boolean)

    A value that indicates whether to copy all tags from the DB cluster to snapshots of the DB cluster. The default is not to copy them.

  • :domain (String)

    The Active Directory directory ID to create the DB cluster in.

    For Amazon Aurora DB clusters, Amazon RDS can use Kerberos Authentication to authenticate users that connect to the DB cluster. For more information, see Kerberos Authentication in the Amazon Aurora User Guide.

  • :domain_iam_role_name (String)

    Specify the name of the IAM role to be used when making API calls to the Directory Service.

  • :enable_global_write_forwarding (Boolean)

    A value that indicates whether to enable write operations to be forwarded from this cluster to the primary cluster in an Aurora global database. The resulting changes are replicated back to this cluster. This parameter only applies to DB clusters that are secondary clusters in an Aurora global database. By default, Aurora disallows write operations for secondary clusters.

  • :destination_region (String)
  • :source_region (String)

    The source region of the snapshot. This is only needed when the shapshot is encrypted and in a different region.

Returns:

    A value that indicates whether to skip the creation of a final DB cluster snapshot before the DB cluster is deleted. If skip is specified, no DB cluster snapshot is created. If skip isn't specified, a DB cluster snapshot is created before the DB cluster is deleted. By default, skip isn't specified, and the DB cluster snapshot is created. By default, this parameter is disabled.

    You must specify a FinalDBSnapshotIdentifier parameter if SkipFinalSnapshot is disabled.

  • :final_db_snapshot_identifier (String)

    The DB cluster snapshot identifier of the new DB cluster snapshot created when SkipFinalSnapshot is disabled.

    Specifying this parameter and also skipping the creation of a final DB cluster snapshot with the SkipFinalShapshot parameter results in an error.

    Constraints:

    • Must be 1 to 255 letters, numbers, or hyphens.

Changing this parameter doesn't result in an outage except in the following case, and the change is applied during the next maintenance window unless the ApplyImmediately is enabled for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.

    Permanent options can't be removed from an option group. The option group can't be removed from a DB cluster once it is associated with a DB cluster.

  • :preferred_backup_window (String)

    The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter.

  • :db_instance_parameter_group_name (String)

    The name of the DB parameter group to apply to all instances of the DB cluster.

    When you apply a parameter group using the DBInstanceParameterGroupName parameter, the DB cluster isn't rebooted automatically. Also, parameter changes aren't applied during the next maintenance window but instead are applied immediately.

    Default: The existing name setting

    Constraints:

    • The DB parameter group must be in the same DB parameter group family as this DB cluster.

    • The DBInstanceParameterGroupName parameter is only valid in combination with the AllowMajorVersionUpgrade parameter.

  • :domain (String)

    For more information, see Using the Data API for Aurora Serverless in the Amazon Aurora User Guide.

  • :copy_tags_to_snapshot (Boolean)

    A value that indicates whether to copy all tags from the DB cluster to snapshots of the DB cluster. The default is not to copy them.

  • :enable_global_write_forwarding (Boolean)

    A value that indicates whether to enable write operations to be forwarded from this cluster to the primary cluster in an Aurora global database. The resulting changes are replicated back to this cluster. This parameter only applies to DB clusters that are secondary clusters in an Aurora global database. By default, Aurora disallows write operations for secondary clusters.

The reader endpoint for the DB cluster. The reader endpoint for a DB cluster load-balances connections across the Aurora Replicas that are available in a DB cluster. As clients request new connections to the reader endpoint, Aurora distributes the connection requests among the Aurora Replicas in the DB cluster. This functionality can help balance your read workload across multiple Aurora Replicas in your DB cluster.

If a failover occurs, and the Aurora 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 Aurora Replicas in the cluster, you can then reconnect to the reader endpoint.

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :db_cluster_identifier (required, String)

    The name of the new DB cluster to be created.

    Constraints:

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

    • First character must be a letter

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

  • :restore_type (String)

    The type of restore to be performed. You can specify one of the following values:

    • full-copy - The new DB cluster is restored as a full copy of the source DB cluster.

    • copy-on-write - The new DB cluster is restored as a clone of the source DB cluster.

    Constraints: You can't specify copy-on-write if the engine version of the source DB cluster is earlier than 1.11.

    If you don't specify a RestoreType value, then the new DB cluster is restored as a full copy of the source DB cluster.

  • :restore_to_time (Time, DateTime, Date, Integer, String)

    The date and time to restore the DB cluster to.

    Valid Values: Value must be a time in Universal Coordinated Time (UTC) format

    Constraints:

    • Must be before the latest restorable time for the DB instance

    • Must be specified if UseLatestRestorableTime parameter isn't provided

    • Can't be specified if the UseLatestRestorableTime parameter is enabled

    • Can't be specified if the RestoreType parameter is copy-on-write

    Example: 2015-03-07T23:45:00Z

  • :use_latest_restorable_time (Boolean)

    A value that indicates whether to restore the DB cluster to the latest restorable backup time. By default, the DB cluster isn't restored to the latest restorable backup time.

    Constraints: Can't be specified if RestoreToTime parameter is provided.

  • :port (Integer)

    The port number on which the new DB cluster accepts connections.

    Constraints: A value from 1150-65535.

    Default: The default port for the engine.

  • :db_subnet_group_name (String)

    The DB subnet group name to use for the new DB cluster.

    Constraints: If supplied, must match the name of an existing DBSubnetGroup.

    Example: mySubnetgroup

  • :option_group_name (String)

    The name of the option group for the new DB cluster.

  • :vpc_security_group_ids (Array<String>)

    A list of VPC security groups that the new DB cluster belongs to.

    A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.

  • :kms_key_id (String)

    The AWS KMS key identifier to use when restoring an encrypted DB cluster from an encrypted DB cluster.

    The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are restoring a DB cluster with the same AWS 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.

    You can restore to a new DB cluster and encrypt the new DB cluster with a KMS key that is different than the KMS key used to encrypt the source DB cluster. The new DB cluster is encrypted with the KMS key identified by the KmsKeyId parameter.

    If you don't specify a value for the KmsKeyId parameter, then the following occurs:

    • If the DB cluster is encrypted, then the restored DB cluster is encrypted using the KMS key that was used to encrypt the source DB cluster.

    • If the DB cluster isn't encrypted, then the restored DB cluster isn't encrypted.

    If DBClusterIdentifier refers to a DB cluster that isn't encrypted, then the restore request is rejected.

  • :enable_iam_database_authentication (Boolean)

    A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled.

    For more information, see IAM Database Authentication in the Amazon Aurora User Guide.

    Currently, Backtrack is only supported for Aurora MySQL DB clusters.

    Default: 0

    Constraints:

    • If specified, this value must be set to a number from 0 to 259,200 (72 hours).

    ^

  • :enable_cloudwatch_logs_exports (Array<String>)

    The list of logs that the restored DB cluster is to export to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon Aurora User Guide.

  • :db_cluster_parameter_group_name (String)

    The name of the DB cluster parameter group to associate with this DB cluster. If this argument is omitted, the default DB cluster parameter group for the specified engine is used.

    Constraints:

    • If supplied, must match the name of an existing DB cluster parameter group.

    • Must be 1 to 255 letters, numbers, or hyphens.

    • First character must be a letter.

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

  • :deletion_protection (Boolean)

    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 disabled.

#wait_until(options = {}) {|resource| ... } ⇒ Resource

Deprecated.

Use [Aws::RDS::Client] #wait_until instead

Note:

The waiting operation is performed on a copy. The original resource remains unchanged.

Waiter polls an API operation until a resource enters a desired state.

Basic Usage

Waiter will polls until it is successful, it fails by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop until condition is true
resource.wait_until(options) {|resource| condition}

Example

instance.wait_until(max_attempts:10, delay:5) do |instance|
  instance.state.name == 'running'
end

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. The waiting condition is set by passing a block to #wait_until:

# poll for ~25 seconds
resource.wait_until(max_attempts:5,delay:5) {|resource|...}

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
# poll for 1 hour, instead of a number of attempts
proc = Proc.new do |attempts, response|
  throw :failure if Time.now - started_at > 3600
end

  # disable max attempts
instance.wait_until(before_wait:proc, max_attempts:nil) {...}

Handling Errors

When a waiter is successful, it returns the Resource. When a waiter fails, it raises an error.

begin
  resource.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

attempts attempt in seconds invoked before each attempt invoked before each wait

Parameters:

  • options (Hash) (defaults to: {})

    a customizable set of options

Options Hash (options):

  • :max_attempts (Integer) — default: 10

    Maximum number of

  • :delay (Integer) — default: 10

    Delay between each

  • :before_attempt (Proc) — default: nil

    Callback

  • :before_wait (Proc) — default: nil

    Callback

Yield Parameters:

  • resource (Resource)

    to be used in the waiting condition.

Returns:

  • (Resource)

    if the waiter was successful

Raises:

  • (Aws::Waiters::Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

    yet successful.

  • (Aws::Waiters::Errors::UnexpectedError)

    Raised when an error is encountered while polling for a resource that is not expected.

  • (NotImplementedError)

    Raised when the resource does not
