Attributes
| Attribute | API Type | Default | Description |
|---|---|---|---|
| DatasetName | AstAdfDatasetBaseNode | Specifies a reference to the dataset used in the dataflow. This is a required reference to an existing definiton. | |
| Name | String | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. This is a required property | |
| AllowSchemaDrift | Boolean | False | Select true if your source columns are likely to change during the dataflow. If marked true, all columns pass through the dataflow to the sink. |
| BatchSize | Int32 | -1 | Size of batches for columnar caching. |
| InferDriftedColumnTypes | Boolean | False | Allow the auto-detection of the data type of drifted columns |
| IsolationLevel | AdfDataflowSourceIsolationLevel | ReadUncommitted | Specifies the SQL read isolation level. |
| PartitionOption | AdfDataflowPartitionOption | CurrentPartitioning | Specifies how the user would like to handle partitioning inside of dataflow components. |
| RowsLimit | Int32 | -1 | Limit of number of rows to be imported. |
| ValidateSchema | Boolean | False | Dataflow will fail if any column in the dataflow is not found in the source. |
