  **Request Syntax**
  ::

    response = client.get_lineage_node(
        domainIdentifier='string',
        identifier='string',
        eventTimestamp=datetime(2015, 1, 1)
    )
    
  :type domainIdentifier: string
  :param domainIdentifier: **[REQUIRED]** 

    The ID of the domain in which you want to get the data lineage node.

    

  
  :type identifier: string
  :param identifier: **[REQUIRED]** 

    The ID of the data lineage node that you want to get.

     

    Both, a lineage node identifier generated by Amazon DataZone and a ``sourceIdentifier`` of the lineage node are supported. If ``sourceIdentifier`` is greater than 1800 characters, you can use lineage node identifier generated by Amazon DataZone to get the node details.

    

  
  :type eventTimestamp: datetime
  :param eventTimestamp: 

    The event time stamp for which you want to get the data lineage node.
