Amazon Relational Database Service

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the cloud. It provides cost-efficient, resizable capacity for an industry-standard relational database and manages common database administration tasks, freeing up developers to focus on what makes their applications and businesses unique.

Amazon RDS gives you access to the capabilities of a MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, Oracle, or Amazon Aurora database server. These capabilities mean that the code, applications, and tools you already use today with your existing databases work with Amazon RDS without modification. Amazon RDS automatically backs up your database and maintains the database software that powers your DB instance. Amazon RDS is flexible: you can scale your database instance's compute resources and storage capacity to meet your application's demand. As with all Amazon Web Services, there are no up-front investments, and you pay only for the resources you use.

This interface reference for Amazon RDS contains documentation for a programming or command line interface you can use to manage Amazon RDS. Note that Amazon RDS is asynchronous, which means that some interfaces might require techniques such as polling or callback functions to determine when a command has been applied. In this reference, the parameter descriptions indicate whether a command is applied immediately, on the next instance reboot, or during the maintenance window. The reference structure is as follows, and we list following some related topics from the user guide.

- Field Detail
  - ENDPOINT_PREFIX
```
static final String ENDPOINT_PREFIX
```
    The region metadata service name for computing region endpoints. You can use this value to retrieve metadata (such as supported regions) of the service.
    
    See Also:
    
    RegionUtils.getRegionsForService(String), Constant Field Values
- Method Detail
  - setEndpoint
```
@Deprecated
void setEndpoint(String endpoint)
```
    Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
    
    Overrides the default endpoint for this client ("rds.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.
    Callers can pass in just the endpoint (ex: "rds.amazonaws.com") or a full URL, including the protocol (ex: "rds.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.
    For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912
    This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    
    endpoint - The endpoint (ex: "rds.amazonaws.com") or a full URL, including the protocol (ex: "rds.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
  - setRegion
```
@Deprecated
void setRegion(Region region)
```
    Deprecated. use AwsClientBuilder#setRegion(String)
    
    An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

  - copyDBClusterSnapshot
```
DBClusterSnapshot copyDBClusterSnapshot(CopyDBClusterSnapshotRequest copyDBClusterSnapshotRequest)
```
    Copies a snapshot of a DB cluster.
    
    To copy a DB cluster snapshot from a shared manual DB cluster snapshot, SourceDBClusterSnapshotIdentifier must be the Amazon Resource Name (ARN) of the shared DB cluster snapshot.
    
    You can copy an encrypted DB cluster snapshot from another AWS Region. In that case, the AWS Region where you call the CopyDBClusterSnapshot action is the destination AWS Region for the encrypted DB cluster snapshot to be copied to. To copy an encrypted DB cluster snapshot from another AWS Region, you must provide the following values:
    - KmsKeyId - The AWS Key Management System (KMS) key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination AWS Region.
    - PreSignedUrl - A URL that contains a Signature Version 4 signed request for the CopyDBClusterSnapshot action to be called in the source AWS Region where the DB cluster snapshot is copied from. The pre-signed URL must be a valid request for the CopyDBClusterSnapshot API action that can be executed in the source AWS Region that contains the encrypted DB cluster snapshot to be copied.
      
      The pre-signed URL request must contain the following parameter values:
      
      KmsKeyId - The KMS key identifier for the key to use to encrypt the copy of the DB cluster snapshot in the destination AWS Region. This is the same identifier for both the CopyDBClusterSnapshot 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 the DB cluster snapshot will be created in.
      
      SourceDBClusterSnapshotIdentifier - The DB cluster snapshot identifier for the encrypted DB cluster snapshot 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 snapshot from the us-west-2 region, then your SourceDBClusterSnapshotIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:cluster-snapshot:aurora-cluster1-snapshot-20161115.
      
      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.
    - TargetDBClusterSnapshotIdentifier - The identifier for the new copy of the DB cluster snapshot in the destination AWS Region.
    - SourceDBClusterSnapshotIdentifier - The DB cluster snapshot identifier for the encrypted DB cluster snapshot to be copied. This identifier must be in the ARN format for the source AWS Region and is the same value as the SourceDBClusterSnapshotIdentifier in the pre-signed URL.
    To cancel the copy operation once it is in progress, delete the target DB cluster snapshot identified by TargetDBClusterSnapshotIdentifier while that DB cluster snapshot is in "copying" status.

  - createDBClusterParameterGroup
```
DBClusterParameterGroup createDBClusterParameterGroup(CreateDBClusterParameterGroupRequest createDBClusterParameterGroupRequest)
```
    Creates a new DB cluster parameter group.
    
    Parameters in a DB cluster parameter group apply to all of the instances in a DB cluster.
    
    A DB cluster parameter group is initially created with the default parameters for the database engine used by instances in the DB cluster. To provide custom values for any of the parameters, you must modify the group after creating it using ModifyDBClusterParameterGroup. Once you've created a DB cluster parameter group, you need to associate it with your DB cluster using ModifyDBCluster. When you associate a new DB cluster parameter group with a running DB cluster, you need to reboot the DB instances in the DB cluster without failover for the new DB cluster parameter group and associated settings to take effect.
    
    After you create a DB cluster parameter group, you should wait at least 5 minutes before creating your first DB cluster that uses that DB cluster parameter group as the default parameter group. This allows Amazon RDS to fully complete the create action before the DB cluster parameter group is used as the default for a new DB cluster. This is especially important for parameters that are critical when creating the default database for a DB cluster, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon RDS console or the DescribeDBClusterParameters command to verify that your DB cluster parameter group has been created or modified.
    
    For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.

  - createEventSubscription
```
EventSubscription createEventSubscription(CreateEventSubscriptionRequest createEventSubscriptionRequest)
```
    Creates an RDS event notification subscription. This action requires a topic ARN (Amazon Resource Name) created by either the RDS console, the SNS console, or the SNS API. To obtain an ARN with 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 type of source (SourceType) you want to be notified of, provide a list of RDS sources (SourceIds) that triggers the events, and provide a list of event categories (EventCategories) for events you want to be notified of. For example, you can specify SourceType = db-instance, SourceIds = mydbinstance1, mydbinstance2 and EventCategories = Availability, Backup.
    
    If you specify both the SourceType and SourceIds, such as SourceType = db-instance and SourceIdentifier = myDBInstance1, you are notified of all the db-instance events for the specified source. If you specify a SourceType but do not specify a SourceIdentifier, you receive notice of the events for that source type for all your RDS sources. If you do not specify either the SourceType nor the SourceIdentifier, you are notified of events generated from all RDS sources belonging to your customer account.
    Parameters:
    
    createEventSubscriptionRequest -

  - deleteDBInstance
```
DBInstance deleteDBInstance(DeleteDBInstanceRequest deleteDBInstanceRequest)
```
    The DeleteDBInstance action deletes a previously provisioned DB instance. When you delete a DB instance, all automated backups for that instance are deleted and cannot be recovered. Manual DB snapshots of the DB instance to be deleted by DeleteDBInstance are not deleted.
    
    If you request a final DB snapshot the status of the Amazon RDS DB instance is deleting until the DB snapshot is created. The API action DescribeDBInstance is used to monitor the status of this operation. The action cannot be canceled or reverted once submitted.
    
    Note that when a DB instance is in a failure state and has a status of failed, incompatible-restore, or incompatible-network, you can only delete it when the SkipFinalSnapshot parameter is set to true.
    
    If the specified DB instance is part of an Amazon Aurora DB cluster, you cannot delete the DB instance if both of the following conditions are true:
    - The DB cluster is a Read Replica of another Amazon Aurora DB cluster.
    - The DB instance is the only instance in the DB cluster.
    To delete a DB instance in this case, first call the PromoteReadReplicaDBCluster API action to promote the DB cluster so it's no longer a Read Replica. After the promotion completes, then call the DeleteDBInstance API action to delete the final instance in the DB cluster.
    Parameters:
    
    deleteDBInstanceRequest -
    
    Returns:
    
    Result of the DeleteDBInstance operation returned by the service.

  - failoverDBCluster
```
DBCluster failoverDBCluster(FailoverDBClusterRequest failoverDBClusterRequest)
```
    Forces a failover for a DB cluster.
    
    A failover for a DB cluster promotes one of the Aurora Replicas (read-only instances) in the DB cluster to be the primary instance (the cluster writer).
    
    Amazon Aurora will automatically fail over to an Aurora Replica, if one exists, when the primary instance fails. You can force a failover when you want to simulate a failure of a primary instance for testing. Because each instance in a DB cluster has its own endpoint address, you will need to clean up and re-establish any existing connections that use those endpoint addresses when the failover is complete.
    
    For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.
    Parameters:
    
    failoverDBClusterRequest -

  - modifyDBClusterParameterGroup
```
ModifyDBClusterParameterGroupResult modifyDBClusterParameterGroup(ModifyDBClusterParameterGroupRequest modifyDBClusterParameterGroupRequest)
```
    Modifies the parameters of a DB cluster parameter group. To modify more than one parameter, submit a list of the following: ParameterName, ParameterValue, and ApplyMethod. A maximum of 20 parameters can be modified in a single request.
    
    For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.
    
    Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB cluster associated with the parameter group before the change can take effect.
    
    After you create a DB cluster parameter group, you should wait at least 5 minutes before creating your first DB cluster that uses that DB cluster parameter group as the default parameter group. This allows Amazon RDS to fully complete the create action before the parameter group is used as the default for a new DB cluster. This is especially important for parameters that are critical when creating the default database for a DB cluster, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon RDS console or the DescribeDBClusterParameters command to verify that your DB cluster parameter group has been created or modified.
    Parameters:
    
    modifyDBClusterParameterGroupRequest -
    
    Returns:
    
    Result of the ModifyDBClusterParameterGroup operation returned by the service.
    
    Throws:
    
    DBParameterGroupNotFoundException - DBParameterGroupName does not refer to an existing DB parameter group.
    
    InvalidDBParameterGroupStateException - The DB parameter group is in use or is in an invalid state. If you are attempting to delete the parameter group, you cannot delete it when the parameter group is in this state.

  - modifyDBClusterSnapshotAttribute
```
DBClusterSnapshotAttributesResult modifyDBClusterSnapshotAttribute(ModifyDBClusterSnapshotAttributeRequest modifyDBClusterSnapshotAttributeRequest)
```
    Adds an attribute and values to, or removes an attribute and values from, a manual DB cluster snapshot.
    
    To share a manual DB cluster snapshot with other AWS accounts, specify restore as the AttributeName and use the ValuesToAdd parameter to add a list of IDs of the AWS accounts that are authorized to restore the manual DB cluster snapshot. Use the value all to make the manual DB cluster snapshot public, which means that it can be copied or restored by all AWS accounts. Do not add the all value for any manual DB cluster snapshots that contain private information that you don't want available to all AWS accounts. If a manual DB cluster snapshot is encrypted, it can be shared, but only by specifying a list of authorized AWS account IDs for the ValuesToAdd parameter. You can't use all as a value for that parameter in this case.
    
    To view which AWS accounts have access to copy or restore a manual DB cluster snapshot, or whether a manual DB cluster snapshot public or private, use the DescribeDBClusterSnapshotAttributes API action.

  - rebootDBInstance
```
DBInstance rebootDBInstance(RebootDBInstanceRequest rebootDBInstanceRequest)
```
    Rebooting a DB instance restarts the database engine service. A reboot also applies to the DB instance any modifications to the associated DB parameter group that were pending. Rebooting a DB instance results in a momentary outage of the instance, during which the DB instance status is set to rebooting. If the RDS instance is configured for MultiAZ, it is possible that the reboot is conducted through a failover. An Amazon RDS event is created when the reboot is completed.
    
    If your DB instance is deployed in multiple Availability Zones, you can force a failover from one AZ to the other during the reboot. You might force a failover to test the availability of your DB instance deployment or to restore operations to the original AZ after a failover occurs.
    
    The time required to reboot is a function of the specific database engine's crash recovery process. To improve the reboot time, we recommend that you reduce database activities as much as possible during the reboot process to reduce rollback activity for in-transit transactions.
    Parameters:
    
    rebootDBInstanceRequest -
    
    Returns:
    
    Result of the RebootDBInstance operation returned by the service.

  - restoreDBClusterToPointInTime
```
DBCluster restoreDBClusterToPointInTime(RestoreDBClusterToPointInTimeRequest restoreDBClusterToPointInTimeRequest)
```
    Restores a DB cluster to an arbitrary point in time. Users can restore to any point in time before LatestRestorableTime for up to BackupRetentionPeriod days. The target DB cluster is created from the source DB cluster with the same configuration as the original DB cluster, except that the new DB cluster is created with the default DB security group.
    
    This action only restores the DB cluster, not the DB instances for that DB cluster. You must invoke the CreateDBInstance action to create DB instances for the restored DB cluster, specifying the identifier of the restored DB cluster in DBClusterIdentifier. You can create DB instances only after the RestoreDBClusterToPointInTime action has completed and the DB cluster is available.
    
    For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.
    
    Parameters:
    
    restoreDBClusterToPointInTimeRequest -

  - restoreDBInstanceFromDBSnapshot
```
DBInstance restoreDBInstanceFromDBSnapshot(RestoreDBInstanceFromDBSnapshotRequest restoreDBInstanceFromDBSnapshotRequest)
```
    Creates a new DB instance from a DB snapshot. The target database is created from the source database restore point with the most of original configuration with the default security group and the default DB parameter group. By default, the new DB instance is created as a single-AZ deployment except when the instance is a SQL Server instance that has an option group that is associated with mirroring; in this case, the instance becomes a mirrored AZ deployment and not a single-AZ deployment.
    
    If your intent is to replace your original DB instance with the new, restored DB instance, then rename your original DB instance before you call the RestoreDBInstanceFromDBSnapshot action. RDS does not allow two DB instances with the same name. Once you have renamed your original DB instance with a different identifier, then you can pass the original name of the DB instance as the DBInstanceIdentifier in the call to the RestoreDBInstanceFromDBSnapshot action. The result is that you will replace the original DB instance with the DB instance created from the snapshot.
    
    If you are restoring from a shared manual DB snapshot, the DBSnapshotIdentifier must be the ARN of the shared DB snapshot.
    
    Parameters:
    
    restoreDBInstanceFromDBSnapshotRequest -
    
    Returns:
    
    Result of the RestoreDBInstanceFromDBSnapshot operation returned by the service.
    
    Throws:

  - shutdown
```
void shutdown()
```
    Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
  - getCachedResponseMetadata
```
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.
    Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
