class PersistingTransformer[M <: ModelWithSummary[M]] extends Model[PersistingTransformer[M]] with ModelTransformer[M, PersistingTransformer[M]]

Utility used to persist portion of data into temporary storage. Usefull for grounding execution plans and avoid massive "skips". Unlike chekpointing is more explicit and controllable.
