NeptuneGraph / Client / start_import_task

start_import_task

NeptuneGraph.Client.start_import_task(**kwargs)

Import data into existing Neptune Analytics graph from Amazon Simple Storage Service (S3). The graph needs to be empty and in the AVAILABLE state.

Request Syntax

response = client.start_import_task(
    importOptions={
        'neptune': {
            's3ExportPath': 'string',
            's3ExportKmsKeyId': 'string',
            'preserveDefaultVertexLabels': True|False,
            'preserveEdgeIds': True|False
        }
    },
    failOnError=True|False,
    source='string',
    format='CSV'|'OPEN_CYPHER',
    graphIdentifier='string',
    roleArn='string'
)

Parameters:

• importOptions (dict) –

  Options for how to perform an import.

  Note

  This is a Tagged Union structure. Only one of the following top level keys can be set: neptune.

  • neptune (dict) –

    Options for importing data from a Neptune database.

    • s3ExportPath (string) – [REQUIRED]

      The path to an S3 bucket from which to import data.

    • s3ExportKmsKeyId (string) – [REQUIRED]

      The KMS key to use to encrypt data in the S3 bucket where the graph data is exported

    • preserveDefaultVertexLabels (boolean) –

      Neptune Analytics supports label-less vertices and no labels are assigned unless one is explicitly provided. Neptune assigns default labels when none is explicitly provided. When importing the data into Neptune Analytics, the default vertex labels can be omitted by setting preserveDefaultVertexLabels to false. Note that if the vertex only has default labels, and has no other properties or edges, then the vertex will effectively not get imported into Neptune Analytics when preserveDefaultVertexLabels is set to false.

    • preserveEdgeIds (boolean) –

      Neptune Analytics currently does not support user defined edge ids. The edge ids are not imported by default. They are imported if preserveEdgeIds is set to true, and ids are stored as properties on the relationships with the property name neptuneEdgeId.

• failOnError (boolean) – If set to true, the task halts when an import error is encountered. If set to false, the task skips the data that caused the error and continues if possible.

• source (string) –

  [REQUIRED]

  A URL identifying the location of the data to be imported. This can be an Amazon S3 path, or can point to a Neptune database endpoint or snapshot.

• format (string) – Specifies the format of Amazon S3 data to be imported. Valid values are CSV, which identifies the Gremlin CSV format or OPENCYPHER, which identies the openCypher load format.

• graphIdentifier (string) –

  [REQUIRED]

  The unique identifier of the Neptune Analytics graph.

• roleArn (string) –

  [REQUIRED]

  The ARN of the IAM role that will allow access to the data that is to be imported.

Return type:

dict

Returns:

Response Structure

• (dict) –

  • graphId (string) –

    The unique identifier of the Neptune Analytics graph.

  • taskId (string) –

    The unique identifier of the import task.

  • source (string) –

    A URL identifying the location of the data to be imported. This can be an Amazon S3 path, or can point to a Neptune database endpoint or snapshot.

  • format (string) –

    Specifies the format of Amazon S3 data to be imported. Valid values are CSV, which identifies the Gremlin CSV format or OPENCYPHER, which identies the openCypher load format.

  • roleArn (string) –

    The ARN of the IAM role that will allow access to the data that is to be imported.

  • status (string) –

    The status of the import task.

  • importOptions (dict) –

    Options for how to perform an import.

    Note

    This is a Tagged Union structure. Only one of the following top level keys will be set: neptune. If a client receives an unknown member it will set SDK_UNKNOWN_MEMBER as the top level key, which maps to the name or tag of the unknown member. The structure of SDK_UNKNOWN_MEMBER is as follows:

    'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}
    

    • neptune (dict) –

      Options for importing data from a Neptune database.

      • s3ExportPath (string) –

        The path to an S3 bucket from which to import data.

      • s3ExportKmsKeyId (string) –

        The KMS key to use to encrypt data in the S3 bucket where the graph data is exported

      • preserveDefaultVertexLabels (boolean) –

        Neptune Analytics supports label-less vertices and no labels are assigned unless one is explicitly provided. Neptune assigns default labels when none is explicitly provided. When importing the data into Neptune Analytics, the default vertex labels can be omitted by setting preserveDefaultVertexLabels to false. Note that if the vertex only has default labels, and has no other properties or edges, then the vertex will effectively not get imported into Neptune Analytics when preserveDefaultVertexLabels is set to false.

      • preserveEdgeIds (boolean) –

        Neptune Analytics currently does not support user defined edge ids. The edge ids are not imported by default. They are imported if preserveEdgeIds is set to true, and ids are stored as properties on the relationships with the property name neptuneEdgeId.
