Service client for accessing Amazon RDS asynchronously. This can be created using the static builder() method. 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.

  - copyDBClusterSnapshot
```
default CompletableFuture<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 region where you call the CopyDBClusterSnapshot action is the destination region for the encrypted DB cluster snapshot to be copied to. To copy an encrypted DB cluster snapshot from another 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 region.
    - PreSignedUrl - A URL that contains a Signature Version 4 signed request for the CopyDBClusterSnapshot action to be called in the source region where the DB cluster snapshot will be copied from. The pre-signed URL must be a valid request for the CopyDBClusterSnapshot API action that can be executed in the source 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 region. This is the same identifier for both the CopyDBClusterSnapshot action that is called in the destination region, and the action contained in the pre-signed URL.
      
      DestinationRegion - The name of the 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 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 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 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.
    
    For more information on copying encrypted DB cluster snapshots from one region to another, see Copying a DB Cluster Snapshot in the Same Account, Either in the Same Region or Across Regions in the Amazon RDS User Guide.
    
    For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.
    Parameters:
    
    copyDBClusterSnapshotRequest -
    
    Returns:
    A Java Future containing the result of the CopyDBClusterSnapshot operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    DBClusterSnapshotAlreadyExistsException User already has a DB cluster snapshot with the given identifier.
    
    DBClusterSnapshotNotFoundException DBClusterSnapshotIdentifier does not refer to an existing DB cluster snapshot.
    
    InvalidDBClusterStateException The DB cluster is not in a valid state.
    
    InvalidDBClusterSnapshotStateException The supplied value is not a valid DB cluster snapshot state.
    
    SnapshotQuotaExceededException Request would result in user exceeding the allowed number of DB snapshots.
    
    KMSKeyNotAccessibleException Error accessing KMS key.
    
    SdkBaseException Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException If any client side error occurs such as an IO related failure, failure to get credentials, etc

  - createDBClusterParameterGroup
```
default CompletableFuture<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.
    Parameters:
    
    createDBClusterParameterGroupRequest -

  - createDBInstanceReadReplica
```
default CompletableFuture<DBInstance> createDBInstanceReadReplica(CreateDBInstanceReadReplicaRequest createDBInstanceReadReplicaRequest)
```
    Creates a DB instance for a DB instance running MySQL, MariaDB, or PostgreSQL that acts as a Read Replica of a source DB instance.
    
    Amazon Aurora does not support this action. You must call the CreateDBInstance action to create a DB instance for an Aurora DB cluster.
    
    All Read Replica DB instances are created as Single-AZ deployments with backups disabled. All other DB instance attributes (including DB security groups and DB parameter groups) are inherited from the source DB instance, except as specified below.
    
    The source DB instance must have backup retention enabled.
    
    You can create an encrypted Read Replica in a different AWS Region than the source DB instance. In that case, the region where you call the CreateDBInstanceReadReplica action is the destination region of the encrypted Read Replica. The source DB instance must be encrypted.
    
    To create an encrypted Read Replica in 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 Read Replica in the destination region.
    - PreSignedUrl - A URL that contains a Signature Version 4 signed request for the CreateDBInstanceReadReplica API action in the AWS region that contains the source DB instance. The PreSignedUrl parameter must be used when encrypting a Read Replica from another AWS region.
      
      The presigned URL must be a valid request for the CreateDBInstanceReadReplica API action that can be executed in the source region that contains the encrypted DB instance. The presigned URL request must contain the following parameter values:
      
      DestinationRegion - The AWS Region that the Read Replica is created in. This region is the same one where the CreateDBInstanceReadReplica action is called that contains this presigned URL.
      
      For example, if you create an encrypted Read Replica in the us-east-1 region, and the source DB instance is in the west-2 region, then you call the CreateDBInstanceReadReplica action in the us-east-1 region and provide a presigned URL that contains a call to the CreateDBInstanceReadReplica action in the us-west-2 region. For this example, the DestinationRegion in the presigned URL must be set to the us-east-1 region.
      
      KmsKeyId - The KMS key identifier for the key to use to encrypt the Read Replica in the destination region. This is the same identifier for both the CreateDBInstanceReadReplica action that is called in the destination region, and the action contained in the presigned URL.
      
      SourceDBInstanceIdentifier - The DB instance identifier for the encrypted Read Replica to be created. This identifier must be in the Amazon Resource Name (ARN) format for the source region. For example, if you create an encrypted Read Replica from a DB instance in the us-west-2 region, then your SourceDBInstanceIdentifier would look like this example: arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-instance-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.
    - DBInstanceIdentifier - The identifier for the encrypted Read Replica in the destination region.
    - SourceDBInstanceIdentifier - The DB instance identifier for the encrypted Read Replica. This identifier must be in the ARN format for the source region and is the same value as the SourceDBInstanceIdentifier in the presigned URL.
    Parameters:
    
    createDBInstanceReadReplicaRequest -
    
    Returns:
    A Java Future containing the result of the CreateDBInstanceReadReplica operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    DBInstanceAlreadyExistsException User already has a DB instance with the given identifier.
    
    InsufficientDBInstanceCapacityException Specified DB instance class is not available in the specified Availability Zone.
    
    DBParameterGroupNotFoundException DBParameterGroupName does not refer to an existing DB parameter group.

    InvalidVPCNetworkStateException DB subnet group does not cover all Availability Zones after it is created because users' change.
    
    ProvisionedIopsNotAvailableInAZException Provisioned IOPS not available in the specified Availability Zone.
    
    OptionGroupNotFoundException The specified option group could not be found.

  - deleteDBInstance
```
default CompletableFuture<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 the following 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:
    A Java Future containing the result of the DeleteDBInstance operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

  - failoverDBCluster
```
default CompletableFuture<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
```
default CompletableFuture<ModifyDBClusterParameterGroupResponse> 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:
    A Java Future containing the result of the ModifyDBClusterParameterGroup operation returned by the service.

  - modifyDBClusterSnapshotAttribute
```
default CompletableFuture<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
```
default CompletableFuture<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 will be 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:
    A Java Future containing the result of the RebootDBInstance operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.

  - restoreDBInstanceFromDBSnapshot
```
default CompletableFuture<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:
    A Java Future containing the result of the RestoreDBInstanceFromDBSnapshot operation returned by the service.

  - restoreDBInstanceToPointInTime
```
default CompletableFuture<DBInstance> restoreDBInstanceToPointInTime(RestoreDBInstanceToPointInTimeRequest restoreDBInstanceToPointInTimeRequest)
```
    Restores a DB instance to an arbitrary point in time. You can restore to any point in time before the time identified by the LatestRestorableTime property. You can restore to a point up to the number of days specified by the BackupRetentionPeriod property.
    
    The target database is created with most of the original configuration, but in a system-selected availability zone, with the default security group, the default subnet 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 deployment and not a single-AZ deployment.
    Parameters:
    
    restoreDBInstanceToPointInTimeRequest -
    
    Returns:
    A Java Future containing the result of the RestoreDBInstanceToPointInTime operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
    
    DBInstanceAlreadyExistsException User already has a DB instance with the given identifier.

    StorageQuotaExceededException Request would result in user exceeding the allowed amount of storage available across all DB instances.
    
    InvalidVPCNetworkStateException DB subnet group does not cover all Availability Zones after it is created because users' change.
    
    InvalidRestoreException Cannot restore from vpc backup to non-vpc DB instance.
    
    DBSubnetGroupNotFoundException DBSubnetGroupName does not refer to an existing DB subnet group.

  - stopDBInstance
```
default CompletableFuture<DBInstance> stopDBInstance(StopDBInstanceRequest stopDBInstanceRequest)
```
    Stops a DB instance. When you stop a DB instance, Amazon RDS retains the DB instance's metadata, including its endpoint, DB parameter group, and option group membership. Amazon RDS also retains the transaction logs so you can do a point-in-time restore if necessary. For more information, see Stopping and Starting a DB instance in the AWS RDS user guide.
    Parameters:
    
    stopDBInstanceRequest -
    
    Returns:
    A Java Future containing the result of the StopDBInstance operation returned by the service.
    The CompletableFuture returned by this method can be completed exceptionally with the following exceptions.
