Updating Vertex Properties in Batches

You can use a specific API provided by GES to update vertex properties in batches. The sample code is as follows:

public static void updateBatchVertice(GraphClient graphClient) throws ApiException 
{
    // Construct the information of a single vertex property.
    Map<String, List<Object>> properties = new HashMap<>();
    properties.put("age", Arrays.asList(20));
    AddVertexReq vertex = new AddVertexReq();
    vertex.setVertexId("Zhang San1");
    vertex.setProperties(properties);

    Map<String, List<Object>> listProperties = new HashMap<>();
    listProperties.put("name", Arrays.asList("teat","mathematics"));
    AddVertexReq vertexWithListProperty = new AddVertexReq();
    vertexWithListProperty.setVertexId("Zhang San0");
    vertexWithListProperty.setProperties(listProperties);

    Map<String, List<Object>> setProperties = new HashMap<>();
    setProperties.put("name", Arrays.asList("a","d"));
    AddVertexReq vertexWithSetProperty = new AddVertexReq();
    vertexWithSetProperty.setVertexId("Zhang San140");
    vertexWithSetProperty.setProperties(setProperties);

    // Form the information of a batch of vertex properties.
    List<AddVertexReq> vertices = new ArrayList<>();
    vertices.add(vertex);
    vertices.add(vertexWithListProperty);
    vertices.add(vertexWithSetProperty);

    // Construct a request for updating vertex properties in batches.
    AddBatchVertexReq updateBatchVertexReq = new AddBatchVertexReq();
    updateBatchVertexReq.setVertices(vertices);

    // Execute the request for updating vertex properties in batches.
    Map<String, Object> result = graphClient.updateBatchVertex("batch-update", updateBatchVertexReq);
}
