is there any Java API without TSDataType to insert records into an existed timeseries?

[holtenko]

I have created some timeseries, and the TSDataType was defined during timeseries creating. I think it's not necessary to input TSDataType when I call API to insert records.
So, is there any Java API without TSDataType to insert records into an existed timeseries? Thank you.

Just like: insertRecord(String deviceId, long time, List<String> measurements, List<Object> values)

iotdb/example/session/src/main/java/org/apache/iotdb/SessionExample.java

Lines 292 to 307 in b103385

	private static void insertStrRecord()
	throws IoTDBConnectionException, StatementExecutionException {
	String deviceId = ROOT_SG1_D1;
	List<String> measurements = new ArrayList<>();
	measurements.add("s1");
	measurements.add("s2");
	measurements.add("s3");
	for (long time = 0; time < 10; time++) {
	List<String> values = new ArrayList<>();
	values.add("1");
	values.add("2");
	values.add("3");
	session.insertRecord(deviceId, time, measurements, values);
	}
	}

Hi @HTHou , thanks for your answer.
I checked the doc(https://iotdb.apache.org/UserGuide/Master/API/Programming-Java-Native-API.html#insert-with-type-inference) of this method, it seems will cost some time to do type inference.
For the existed timeseries, does it still have the time cost for type inference?

[HTHou]

Yes, it will take some time to do type inference.

Actually, I think it is possible to add a Syntactic sugar about what you want. Just using the actual Object type of value to infer the TsDataType in the Session, and then send the values and TsDataTypes to server.

Thank you @HTHou
