val breakDataFrameLineage: Boolean

Stop propagating input DataFrame through action and instead get a new DataFrame from DataObject.
Stop propagating input DataFrame through action and instead get a new DataFrame from DataObject. This can help to save memory and performance if the input DataFrame includes many transformations from previous Actions. The new DataFrame will be initialized according to the SubFeed's partitionValues.
