    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.

    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.

  • :engine_mode (String)

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

  • :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.

  • :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.

    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.

    Default: 0

    Constraints:

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

    ^

    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.

  • :tags (Array<Types::Tag>)

    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.

  • :backtrack_window (Integer)

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

    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.

  • :copy_tags_to_snapshot (Boolean)

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

Returns:

snapshots = db_cluster.snapshots({
  db_cluster_snapshot_identifier: "String",
  snapshot_type: "String",
  filters: [
    {
      name: "String", # required
      values: ["String"], # required
    },
  ],

  include_public: false,
})

Parameters:

  • options (Hash) (defaults to: {})

    ({})

Options Hash (options):

  • :db_cluster_snapshot_identifier (String)

    A specific DB cluster snapshot identifier to describe. This parameter can't be used in conjunction with the DBClusterIdentifier parameter. This value is stored as a lowercase string.

    Constraints:

    • If supplied, must match the identifier of an existing DBClusterSnapshot.

    • If this identifier is for an automated snapshot, the SnapshotType parameter must also be specified.

  • :snapshot_type (String)

    The type of DB cluster snapshots to be returned. You can specify one of the following values:

    • automated - Return all DB cluster snapshots that have been automatically taken by Amazon RDS for my AWS account.

    • manual - Return all DB cluster snapshots that have been taken by my AWS account.

    • shared - Return all manual DB cluster snapshots that have been shared to my AWS account.

    • public - Return all DB cluster snapshots that have been marked as public.

    If you don't specify a SnapshotType value, then both automated and manual DB cluster snapshots are returned. You can include shared DB cluster snapshots with these results by enabling the IncludeShared parameter. You can include public DB cluster snapshots with these results by enabling the IncludePublic parameter.

    The IncludeShared and IncludePublic parameters don't apply for SnapshotType values of manual or automated. The IncludePublic parameter doesn't apply when SnapshotType is set to shared. The IncludeShared parameter doesn't apply when SnapshotType is set to public.

  • :filters (Array<Types::Filter>)

    A filter that specifies one or more DB cluster snapshots to describe.

    Supported filters:

    • db-cluster-id - Accepts DB cluster identifiers and DB cluster Amazon Resource Names (ARNs).

    • db-cluster-snapshot-id - Accepts DB cluster snapshot identifiers.

    • snapshot-type - Accepts types of DB cluster snapshots.

    • engine - Accepts names of database engines.

  • :max_records (Integer)

    The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so you can retrieve the remaining results.

    Default: 100

    Constraints: Minimum 20, maximum 100.

  • :marker (String)

    An optional pagination token provided by a previous DescribeDBClusterSnapshots request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

  • :include_shared (Boolean)

    A value that indicates whether to include shared manual DB cluster snapshots from other AWS accounts that this AWS account has been given permission to copy or restore. By default, these snapshots are not included.

    You can give an AWS account permission to restore a manual DB cluster snapshot from another AWS account by the ModifyDBClusterSnapshotAttribute API action.

  • :include_public (Boolean)

    A value that indicates whether to include manual DB cluster snapshots that are public and can be copied or restored by any AWS account. By default, the public snapshots are not included.

    You can share a manual DB cluster snapshot as public by using the ModifyDBClusterSnapshotAttribute API action.

#wait_until(options = {}, &block) ⇒ 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) {|instance| instance.state.name == 'running' }

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

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
