update created by (ownerid) and last modified by in apex

I have created an integration user account with name Integration User. How can I update the created by (ownerid) and last updated by fields with the details of this integration user while doing a bulk dml insert in apex? Right now its showing the logged in users name when the apex class is run.
  
// records to be updated received from json
jsonBody = '[{"count__c":"445", "downloads__c":"340"}, {"count__c":"440", "downloads__c":"240"}]';

List<Data__c> dList = (List<Data__c>) System.JSON.deserialize(jsonBody, List<Data__c>.class);

countList has unique count__c values, say: 445,440 // to use in the IN clause.

// Querry parent for those plan ids in daily data json
List<Parent__c> parentList = [SELECT Id, Name FROM Parent__c 
    WHERE count__c IN :countList];

List<Data__c> dataToInsert = new List<Data__c>();

// Loop through dList - inner loop
for(Data__c dRecords : dList) {
     for(Parent__c parentRecords : parentList) {         
          if(dRecords.count__c  == parentRecords.count__c) {
                dRecords.downloads__c  = parentRecords.downloads__c ;
                dataToInsert.add(dRecords );
           }
      } 
} 
insert dataToInsert;

Hi,

We can only do this while inserting a record. You should activate the create audit fields for that. Please find the below article for more details on it.

public class JSON2Apex {

    public String count__c {get;set;} 
    public String downloads__c {get;set;} 

    public JSON2Apex(JSONParser parser) {
        while (parser.nextToken() != System.JSONToken.END_OBJECT) {
            if (parser.getCurrentToken() == System.JSONToken.FIELD_NAME) {
                String text = parser.getText();
                if (parser.nextToken() != System.JSONToken.VALUE_NULL) {
                    if (text == 'count__c') {
                        count__c = parser.getText();
                    } else if (text == 'downloads__c') {
                        downloads__c = parser.getText();
                    } else {
                        System.debug(LoggingLevel.WARN, 'JSON2Apex consuming unrecognized property: '+text);
                        consumeObject(parser);
                    }
                }
            }
        }
    }
    
    
    public static JSON2Apex parse(String json) {
        System.JSONParser parser = System.JSON.createParser(json);
        return new JSON2Apex(parser);
    }
    
    public static void consumeObject(System.JSONParser parser) {
        Integer depth = 0;
        do {
            System.JSONToken curr = parser.getCurrentToken();
            if (curr == System.JSONToken.START_OBJECT || 
                curr == System.JSONToken.START_ARRAY) {
                depth++;
            } else if (curr == System.JSONToken.END_OBJECT ||
                curr == System.JSONToken.END_ARRAY) {
                depth--;
            }
        } while (depth > 0 && parser.nextToken() != null);
    }
    


}






TEST CLASS:

@IsTest
public class JSON2Apex_Test {
    
    // This test method should give 100% coverage
    static testMethod void testParse() {
        String json = '{\"count__c\":\"445\", \"downloads__c\":\"340\"}, {\"count__c\":\"440\", \"downloads__c\":\"240\"}';
        JSON2Apex r = JSON2Apex.parse(json);
        System.assert(r != null);

        json = '{\"TestAMissingObject\": { \"TestAMissingArray\": [ { \"TestAMissingProperty\": \"Some Value\" } ] } }';
        JSON2Apex objJSON2Apex = new JSON2Apex(System.JSON.createParser(json));
        System.assert(objJSON2Apex != null);
        System.assert(objJSON2Apex.count__c == null);
        System.assert(objJSON2Apex.downloads__c == null);
    }
