    Break lineage.

    Break lineage. This means to discard an existing DataFrame or List of FileRefs, so that it is requested again from the DataObject. On one side this is usable to break long DataFrame Lineages over multiple Actions and instead reread the data from an intermediate table. On the other side it is needed if partition values or filter condition are changed.
