## Methods detail

# `public static `Aws\Redshift\RedshiftClient``
`factory( array|`Guzzle\Common\Collection` $config = array() )`

Factory method to create a new Amazon Redshift client using an array of configuration options.

#### Parameters

$config
  `array|`Guzzle\Common\Collection``
  $config Client configuration data

#### Returns

``Aws\Redshift\RedshiftClient``

# `public `Guzzle\Service\Resource\Model``
`authorizeClusterSecurityGroupIngress( array $args = array() )`

Executes the AuthorizeClusterSecurityGroupIngress operation.

Adds an inbound (ingress) rule to an Amazon Redshift security group. Depending on whether the application accessing your cluster is running on the Internet or an EC2 instance, you can authorize inbound access to either a Classless Interdomain Routing (CIDR) IP address range or an EC2 security group. You can add as many as 20 ingress rules to an Amazon Redshift security group.

The EC2 security group must be defined in the AWS region where the cluster resides.

For an overview of CIDR blocks, see the Wikipedia article on Classless Inter-Domain Routing.

You must also associate the security group with a cluster so that clients running on these IP addresses or the EC2 instance are authorized to connect to the cluster. For information about managing security groups, go to Working with Security Groups in the Amazon Redshift Cluster Management Guide.

#### Examples

# `public `Guzzle\Service\Resource\Model``
`createEventSubscription( array $args = array() )`

Executes the CreateEventSubscription operation.

Creates an Amazon Redshift event notification subscription. This action requires an ARN (Amazon Resource Name) of an Amazon SNS topic created by either the Amazon Redshift console, the Amazon SNS console, or the Amazon SNS API. To obtain an ARN with Amazon SNS, you must create a topic in Amazon SNS and subscribe to the topic. The ARN is displayed in the SNS console.

You can specify the source type, and lists of Amazon Redshift source IDs, event categories, and event severities. Notifications will be sent for all events you want that match those criteria. For example, you can specify source type = cluster, source ID = my-cluster-1 and mycluster2, event categories = Availability, Backup, and severity = ERROR. The subscription will only send notifications for those ERROR events in the Availability and Backup categories for the specified clusters.

If you specify both the source type and source IDs, such as source type = cluster and source identifier = my-cluster-1, notifications will be sent for all the cluster events for my-cluster-1. If you specify a source type but do not specify a source identifier, you will receive notice of the events for the objects of that type in your AWS account. If you do not specify either the SourceType nor the SourceIdentifier, you will be notified of events generated from all Amazon Redshift sources belonging to your AWS account. You must specify a source type if you specify a source ID.

# `public `Guzzle\Service\Resource\Model``
`deleteCluster( array $args = array() )`

Executes the DeleteCluster operation.

Deletes a previously provisioned cluster. A successful response from the web service indicates that the request was received correctly. Use DescribeClusters to monitor the status of the deletion. The delete operation cannot be canceled or reverted once submitted. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide .

If you want to shut down the cluster and retain it for future use, set SkipFinalClusterSnapshot to false and specify a name for FinalClusterSnapshotIdentifier. You can later restore this snapshot to resume using the cluster. If a final cluster snapshot is requested, the status of the cluster will be "final-snapshot" while the snapshot is being taken, then it's "deleting" once Amazon Redshift begins deleting the cluster.

For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide .

`describeClusters( array $args = array() )`

Executes the DescribeClusters operation.

Returns properties of provisioned clusters including general cluster properties, cluster database properties, maintenance and backup properties, and security and access properties. This operation supports pagination. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide .

If you specify both tag keys and tag values in the same request, Amazon Redshift returns all clusters that match any combination of the specified keys and values. For example, if you have owner and environment for tag keys, and admin and test for tag values, all clusters that have any combination of those values are returned.

If both tag keys and values are omitted from the request, clusters are returned regardless of whether they have tag keys or values associated with them.

#### Examples

- Basic formatting example

      $result = $client->describeClusters(array(
          'ClusterIdentifier' => 'string',

# `public `Guzzle\Service\Resource\Model``
`describeTags( array $args = array() )`

Executes the DescribeTags operation.

Returns a list of tags. You can return tags from a specific resource by specifying an ARN, or you can return all tags for a given type of resource, such as clusters, snapshots, and so on.

The following are limitations for DescribeTags :

- You cannot specify an ARN and a resource-type value together in the same request.
- You cannot use the MaxRecords and Marker parameters together with the ARN parameter.
- The MaxRecords parameter can be a range from 10 to 50 results to return in a request.

If you specify both tag keys and tag values in the same request, Amazon Redshift returns all resources that match any combination of the specified keys and values. For example, if you have owner and environment for tag keys, and admin and test for tag values, all resources that have any combination of those values are returned.

If both tag keys and values are omitted from the request, resources are returned regardless of whether they have tag keys or values associated with them.

#### Examples

- Basic formatting example

      $result = $client->describeTags(array(
          'ResourceName' => 'string',
          'ResourceType' => 'string',

`modifyCluster( array $args = array() )`

Executes the ModifyCluster operation.

Modifies the settings for a cluster. For example, you can add another security or parameter group, update the preferred maintenance window, or change the master user password. Resetting a cluster password or modifying the security groups associated with a cluster do not need a reboot. However, modifying a parameter group requires a reboot for parameters to take effect. For more information about managing clusters, go to Amazon Redshift Clusters in the Amazon Redshift Cluster Management Guide .

You can also change node type and the number of nodes to scale up or down the cluster. When resizing a cluster, you must specify both the number of nodes and the node type even if one of the parameters does not change.

      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - ClusterIdentifier => (string)

    The unique identifier of the cluster to be modified.

    Example: examplecluster

  - ClusterType => (string)

    The new cluster type.

    When you submit your cluster resize request, your existing cluster goes into a read-only mode. After Amazon Redshift provisions a new cluster based on your resize requirements, there will be outage for a period while the old cluster is deleted and your connection is switched to the new cluster. You can use DescribeResize to track the progress of the resize request.

    Valid Values: multi-node | single-node

  - NodeType => (string)

    The new node type of the cluster. If you specify a new node type, you must also specify the number of nodes parameter.

    When you submit your request to resize a cluster, Amazon Redshift sets access permissions for the cluster to read-only. After Amazon Redshift provisions a new cluster according to your resize requirements, there will be a temporary outage while the old cluster is deleted and your connection is switched to the new cluster. When the new connection is complete, the original access permissions for the cluster are restored. You can use DescribeResize to track the progress of the resize request.

    Valid Values: ds1.xlarge | ds1.8xlarge | ds2.xlarge | ds2.8xlarge | dc1.large | dc1.8xlarge.

  - NumberOfNodes => (int)

    The new number of nodes of the cluster. If you specify a new number of nodes, you must also specify the node type parameter.

    When you submit your request to resize a cluster, Amazon Redshift sets access permissions for the cluster to read-only. After Amazon Redshift provisions a new cluster according to your resize requirements, there will be a temporary outage while the old cluster is deleted and your connection is switched to the new cluster. When the new connection is complete, the original access permissions for the cluster are restored. You can use DescribeResize to track the progress of the resize request.

    Valid Values: Integer greater than 0.

  - ClusterSecurityGroups => (array<string>)

  - VpcSecurityGroupIds => (array<string>)

    A list of virtual private cloud (VPC) security groups to be associated with the cluster.

  - MasterUserPassword => (string)

    The new password for the cluster master user. This change is asynchronously applied as soon as possible. Between the time of the request and the completion of the request, the MasterUserPassword element exists in the PendingModifiedValues element of the operation response. Operations never return the password, so this operation provides a way to regain access to the master user account for a cluster if the password is lost.

    Default: Uses existing setting.

    Constraints:

    - Must be between 8 and 64 characters in length.
    - Must contain at least one uppercase letter.

    Default: Uses existing setting.

    Constraints: The cluster parameter group must be in the same parameter group family that matches the cluster version.

  - AutomatedSnapshotRetentionPeriod => (int)

    The number of days that automated snapshots are retained. If the value is 0, automated snapshots are disabled. Even if automated snapshots are disabled, you can still create manual snapshots when you want with CreateClusterSnapshot.

    If you decrease the automated snapshot retention period from its current value, existing automated snapshots that fall outside of the new retention period will be immediately deleted.

    Default: Uses existing setting.

    Constraints: Must be a value from 0 to 35.

  - PreferredMaintenanceWindow => (string)

    The weekly time range (in UTC) during which system maintenance can occur, if necessary. If system maintenance is necessary during the window, it may result in an outage.

    This maintenance window change is made immediately. If the new maintenance window indicates the current time, there must be at least 120 minutes between the current time and end of the window in order to ensure that pending changes are applied.

    Default: Uses existing setting.

    Format: ddd:hh24:mi-ddd:hh24:mi, for example wed:07:30-wed:08:00.

    Valid Days: Mon | Tue | Wed | Thu | Fri | Sat | Sun

    Constraints: Must be at least 30 minutes.

  - ClusterVersion => (string)

    The new version number of the Amazon Redshift engine to upgrade to.

    For major version upgrades, if a non-default cluster parameter group is currently in use, a new cluster parameter group in the cluster parameter group family for the new version must be specified. The new cluster parameter group can be the default for that cluster parameter group family. For more information about parameters and parameter groups, go to Amazon Redshift Parameter Groups in the Amazon Redshift Cluster Management Guide.

# `public `Guzzle\Service\Resource\Model``
`restoreFromClusterSnapshot( array $args = array() )`

Executes the RestoreFromClusterSnapshot operation.

Creates a new cluster from a snapshot. By default, Amazon Redshift creates the resulting cluster with the same configuration as the original cluster from which the snapshot was created, except that the new cluster is created with the default cluster security and parameter groups. After Amazon Redshift creates the cluster, you can use the ModifyCluster API to associate a different security group and different parameter group with the restored cluster. If you are using a DS node type, you can also choose to change to another DS node type of the same size during restore.

If you restore a cluster into a VPC, you must provide a cluster subnet group where you want the cluster restored.

For more information about working with snapshots, go to Amazon Redshift Snapshots in the Amazon Redshift Cluster Management Guide.
