Description

Sometimes, user may call `insertRecords()` to write data in batch, while all the records belong to the same device.

However, IoTDB server will consider these records without any relation. As a result, the server will contend the write lock for each record, which is time consuming.

 

Therefore, I come up with a new API, insertRecordsOfOneDevice, that write data that belong the the same device in batch.

 

API:

public void insertRecordsOfOneDevice(String deviceId, List<Long> times,
List<List<String>> measurementsList, List<List<TSDataType>> typesList,
List<List<Object>> valuesList)

 

Tasks:

1. java API implementation
2. another API that users may do not know the value type. 
3. Python API
4. Go API
