How to specify the field type that may be automatically set up when inserting data into Apache IoTDB?

I have a question about Apache IoTDB. The value of a certain field in my database is 1, but when I queried this value, the value returned 1.0. Does that may because my fields are automatically created when inserting data? (Since I don't remember I setup any data type) And also how do I specify my data type of these fields in this case?

Yes, the data type of Apache IoTDB is automatically determined based on the value of the written data. If you want to change, in this case, from 1.0 to 1 for your data type, you can use integer_string_infer_type to change the data type inferred from the integer string. The default setting of this parameter is FLOAT, so that's why you got 1.0.
