CompositePersistenceManager

class sparklightautoml.dataset.persistence.CompositePersistenceManager(level2manager, parent=None)[source]

Bases: BasePersistenceManager

Universal composite manager that can combine other manager to apply different storing strategies on different levels.

For BucketedPersistenceManager all unpersisting operations are delayed until the end of automl processing, due to possible loss of source for downstream persistence manager if they don’t use external storage and files.
