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.

  - createDBClusterParameterGroup
```
public DBClusterParameterGroup createDBClusterParameterGroup(CreateDBClusterParameterGroupRequest request)
```
    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.
    
    Specified by:
    
    createDBClusterParameterGroup in interface AmazonNeptune
    
    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
```
public EventSubscription createEventSubscription(CreateEventSubscriptionRequest request)
```
    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.

  - failoverDBCluster
```
public DBCluster failoverDBCluster(FailoverDBClusterRequest request)
```
    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.
    
    Specified by:
    
    failoverDBCluster in interface AmazonNeptune
    
    Parameters:
    
    failoverDBClusterRequest -

  - modifyDBClusterParameterGroup
```
public ModifyDBClusterParameterGroupResult modifyDBClusterParameterGroup(ModifyDBClusterParameterGroupRequest request)
```
    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.
    
    Specified by:
    
    modifyDBClusterParameterGroup in interface AmazonNeptune
    
    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
```
public DBClusterSnapshotAttributesResult modifyDBClusterSnapshotAttribute(ModifyDBClusterSnapshotAttributeRequest request)
```
    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 Amazon accounts, specify restore as the AttributeName and use the ValuesToAdd parameter to add a list of IDs of the Amazon 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 Amazon 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 Amazon accounts. If a manual DB cluster snapshot is encrypted, it can be shared, but only by specifying a list of authorized Amazon account IDs for the ValuesToAdd parameter. You can't use all as a value for that parameter in this case.
    
    To view which Amazon 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.
    
    Specified by:
    
    modifyDBClusterSnapshotAttribute in interface AmazonNeptune
    
    Parameters:
    
    modifyDBClusterSnapshotAttributeRequest -

  - getCachedResponseMetadata
```
public 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 the request.
    
    Specified by:
    
    getCachedResponseMetadata in interface AmazonNeptune
    
    Parameters:
    
    request - The originally executed request
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
