- **min**: The minimum value of the column/label of the data type. The generated value will equal or large than the minimum value.
- **max**: The maximum value of the column/label of the data type. The generated value will less than the maximum value.
- **fun**: This column of data is filled with functions. Currently, only the sin and cos functions are supported, with input parameters of angle ranging from 0 to 360 degrees. It also supports coefficient adjustment and random fluctuation factor adjustment, and is presented in a fixed format expression. For example, fun="10*sin(x)+100*random(5)", where x represents the angle, which will increase from 0 to 360 degrees, then recover to 0 and continue to increase to 360 degrees, with each increase step size of 1 degree. 10 represents the coefficient of multiplication, 100 represents the coefficient of addition or subtraction, and 5 represents the fluctuation range within a random range of 5%. The currently supported data type is int32_ T, int64_ t. There are four data types: float and double. Note: The expression is in a fixed mode and cannot be reversed. There must be no spaces in the middle, otherwise parsing will fail.
- **values**: The value field of the nchar/binary column/label, which will be chosen randomly from the values.
