Amazon Neptune

Amazon Neptune is a fast, reliable, fully-managed graph database service that makes it easy to build and run applications that work with highly connected datasets. The core of Amazon Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with milliseconds latency. Amazon Neptune supports popular graph models Property Graph and W3C's RDF, and their respective query languages Apache TinkerPop Gremlin and SPARQL, allowing you to easily build queries that efficiently navigate highly connected datasets. Neptune powers graph use cases such as recommendation engines, fraud detection, knowledge graphs, drug discovery, and network security.

This interface reference for Amazon Neptune contains documentation for a programming or command line interface you can use to manage Amazon Neptune. Note that Amazon Neptune 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
```
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 (AWS 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 AWS Region, then your SourceDBClusterSnapshotIdentifier looks like the following example: arn:aws:rds:us-west-2:123456789012:cluster-snapshot:neptune-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.
    Parameters:
    
    copyDBClusterSnapshotRequest -
    
    Returns:
    
    Result of the CopyDBClusterSnapshot operation returned by the service.
    
    Throws:
    
    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.

    Parameters:
    
    copyDBParameterGroupRequest -
    
    Returns:
    
    Result of the CopyDBParameterGroup operation returned by the service.
    
    Throws:

  - createDBCluster
```
DBCluster createDBCluster(CreateDBClusterRequest createDBClusterRequest)
```
    Creates a new Amazon Neptune DB cluster.
    
    You can use the ReplicationSourceIdentifier parameter to create the DB cluster as a Read Replica of another DB cluster or Amazon Neptune DB instance. For cross-region replication where the DB cluster identified by ReplicationSourceIdentifier is encrypted, you must also specify the PreSignedUrl parameter.
    
    Parameters:
    
    createDBClusterRequest -
    
    Returns:
    
    Result of the CreateDBCluster operation returned by the service.
    
    Throws:
    
    DBClusterAlreadyExistsException - User already has a DB cluster with the given identifier.
    
    InsufficientStorageClusterCapacityException - There is insufficient storage available for the current action. You may be able to resolve this error by updating your subnet group to use different Availability Zones that have more storage available.
    
    DBClusterQuotaExceededException - User attempted to create a new DB cluster and the user has already reached the maximum allowed DB cluster quota.
    
    StorageQuotaExceededException - Request would result in user exceeding the allowed amount of storage available across all DB instances.
    
    DBSubnetGroupNotFoundException - DBSubnetGroupName does not refer to an existing DB subnet group.
    
    InvalidVPCNetworkStateException - DB subnet group does not cover all Availability Zones after it is created because users' change.
    
    InvalidDBClusterStateException - The DB cluster is not in a valid state.
    
    InvalidDBSubnetGroupStateException - The DB subnet group cannot be deleted because it is in use.
    
    InvalidSubnetException - The requested subnet is invalid, or multiple subnets were requested that are not all in a common VPC.
    
    InvalidDBInstanceStateException - The specified DB instance is not in the available state.
    
    DBClusterParameterGroupNotFoundException - DBClusterParameterGroupName does not refer to an existing DB Cluster parameter group.
    
    KMSKeyNotAccessibleException - Error accessing KMS key.
    
    DBClusterNotFoundException - DBClusterIdentifier does not refer to an existing DB cluster.
    
    DBInstanceNotFoundException - DBInstanceIdentifier does not refer to an existing DB instance.

  - 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 Neptune 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 Neptune console or the DescribeDBClusterParameters command to verify that your DB cluster parameter group has been created or modified.
    
    Parameters:
    
    createDBClusterParameterGroupRequest -
    
    Returns:
    
    Result of the CreateDBClusterParameterGroup operation returned by the service.
    
    Throws:
    
    DBParameterGroupQuotaExceededException - Request would result in user exceeding the allowed number of DB parameter groups.
    
    DBParameterGroupAlreadyExistsException - A DB parameter group with the same name exists.

  - createEventSubscription
```
EventSubscription createEventSubscription(CreateEventSubscriptionRequest createEventSubscriptionRequest)
```
    Creates an event notification subscription. This action requires a topic ARN (Amazon Resource Name) created by either the Neptune 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 Neptune 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 Neptune sources. If you do not specify either the SourceType nor the SourceIdentifier, you are notified of events generated from all Neptune sources belonging to your customer account.
    
    Parameters:
    
    createEventSubscriptionRequest -
    
    Returns:
    
    Result of the CreateEventSubscription operation returned by the service.

  - 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 can't 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 Neptune 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 can't 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 a DB cluster, you can't delete the DB instance if both of the following conditions are true:
    - The DB cluster is a Read Replica of another 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.
    
    Throws:
    
    DBInstanceNotFoundException - DBInstanceIdentifier does not refer to an existing DB instance.
    
    InvalidDBInstanceStateException - The specified DB instance is not in the available state.
    
    DBSnapshotAlreadyExistsException - DBSnapshotIdentifier is already used by an existing snapshot.
    
    SnapshotQuotaExceededException - Request would result in user exceeding the allowed number of DB snapshots.
    
    InvalidDBClusterStateException - The DB cluster is not in a valid state.

  - failoverDBCluster
```
DBCluster failoverDBCluster(FailoverDBClusterRequest failoverDBClusterRequest)
```
    Forces a failover for a DB cluster.
    
    A failover for a DB cluster promotes one of the Read Replicas (read-only instances) in the DB cluster to be the primary instance (the cluster writer).
    
    Amazon Neptune will automatically fail over to a Read 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.
    
    Parameters:
    
    failoverDBClusterRequest -
    
    Returns:
    
    Result of the FailoverDBCluster operation returned by the service.
    
    Throws:

  - 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.
    
    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 Neptune 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 Neptune 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.
    
    Parameters:
    
    modifyDBClusterSnapshotAttributeRequest -
    
    Returns:
    
    Result of the ModifyDBClusterSnapshotAttribute operation returned by the service.
    
    Throws:
    
    DBClusterSnapshotNotFoundException - DBClusterSnapshotIdentifier does not refer to an existing DB cluster snapshot.
    
    InvalidDBClusterSnapshotStateException - The supplied value is not a valid DB cluster snapshot state.

  - modifyDBParameterGroup
```
ModifyDBParameterGroupResult modifyDBParameterGroup(ModifyDBParameterGroupRequest modifyDBParameterGroupRequest)
```
    Modifies the parameters of a DB 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.
    
    Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB instance associated with the parameter group before the change can take effect.
    
    After you modify a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB parameter group as the default parameter group. This allows Amazon Neptune to fully complete the modify action before the parameter group is used as the default for a new DB instance. This is especially important for parameters that are critical when creating the default database for a DB instance, 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 Neptune console or the DescribeDBParameters command to verify that your DB parameter group has been created or modified.
    
    Parameters:
    
    modifyDBParameterGroupRequest -
    
    Returns:
    
    Result of the ModifyDBParameterGroup 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.

  - 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.
    
    Parameters:
    
    restoreDBClusterToPointInTimeRequest -
    
    Returns:
    
    Result of the RestoreDBClusterToPointInTime operation returned by the service.

  - 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.
