Transformations

.. automodule:: rdc.etl.transform

Transformations are the basic bricks to build ETL processes. Basically, it gets lines from its input and sends transformed lines to its output.

You're highly encouraged to use the rdc.etl.transform.Transform class as a base for your custom transforms, as it defines the whole :doc:`I/O logic <io>`. All transformations provided by the package are subclasses of rdc.etl.transform.Transform.
