 ** columnName **   <a name="API-Type-SyntheticDataColumnProperties-columnName"></a>
The name of the data column as it appears in the dataset.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 128.  
Pattern: `[a-z0-9_](([a-z0-9_]+-)*([a-z0-9_]+))?`   
Required: Yes

 ** columnType **   <a name="API-Type-SyntheticDataColumnProperties-columnType"></a>
The data type of the column, which determines how the synthetic data generation algorithm processes and synthesizes values for this column.  
Type: String  
Valid Values: `CATEGORICAL | NUMERICAL`   
Required: Yes

 ** isPredictiveValue **   <a name="API-Type-SyntheticDataColumnProperties-isPredictiveValue"></a>
Indicates if this column contains predictive values that should be treated as target variables in machine learning models. This affects how the synthetic data generation preserves statistical relationships.  
Type: Boolean
