In IronPython API, DataSourceOperations
class has the ReplaceDataFlow()
method which allows Data Table replacement without affecting downstream Data Transformation steps, similar to manually replacing in Data Canvas (i.e., click on table > Replace data source).
This method is not available for DataTableDataSourceOperations
class; it has the ReplaceData()
method, which removes all downstream Data Transformation steps.
Having to re-add the deleted Data Transformation steps is tedious.
Hi Ivan, thank you for contributing. I have a little problem understanding the idea. Do you want an API for changing data table in DataTableDataSourceOperation? And that such call would not affect any downstream transformation steps?
