Interfaces are provided to increase the proficiency of bulking inserting nodes/edges.

Data Types

Mapping table for Java and Ultipa data types:

insertBulkNodes

Example:

List<Property> propertyList = new ArrayList<>();
Property name = new Property();
name.setName("name");
name.setType(Ultipa.PropertyType.STRING);
propertyList.add(name);
Property age = new Property();
age.setName("age");
age.setType(Ultipa.PropertyType.INT32);
propertyList.add(age);

List<Node> nodeList = new ArrayList<>();
Node person1 = new Node();
person1.setSchema("person");
person1.setID("1");
Value value1 = new Value();
value1.put("name","person1");
value1.put("age",10);
person1.setValues(value1);
nodeList.add(person1);

Node person2 = new Node();
person2.setSchema("person");
person2.setID("2");
Value value2 = new Value();
value2.put("name","person2");
value2.put("age",20);
person2.setValues(value2);
nodeList.add(person2);

Response response = client.insertBulkNodes("person",propertyList,nodeList,Ultipa.InsertType.NORMAL,false);

insertBulkEdges

Example:

  List<Property> propertyList = new ArrayList<>();
  Property typeProp = new Property();
  typeProp.setName("type");
  typeProp.setType(Ultipa.PropertyType.STRING);
  propertyList.add(typeProp);
  Property amountProp = new Property();
  amountProp.setName("amount");
  amountProp.setType(Ultipa.PropertyType.DOUBLE);
  propertyList.add(amountProp);

  List<Edge> edgeList = new ArrayList<>();
  Edge edge1 = new Edge();
  edge1.setSchema("transfer");
  edge1.setFrom("1001");
  edge1.setTo("1002");
  Value value1 = new Value();
  value1.put("type", "1");
  value1.put("amount",100.0);
  edge1.setValues(value1);
  edgeList.add(edge1);

  Edge edge2 = new Edge();
  edge2.setSchema("transfer");
  edge2.setFrom("1002");
  edge2.setTo("1003");
  Value value2 = new Value();
  value2.put("type", "2");
  value2.put("amount",200.0);
  edge2.setValues(value2);
  edgeList.add(edge2);

  Response response = client.insertBulkEdges("transfer",propertyList,edgeList,Ultipa.InsertType.NORMAL,false);
