    Methodā—Since v1.1

    checkpoint

    Copy
    checkpoint(
        self,
    ) -> Any
    View source on GitHub

    Return stored representation: always DELTA_SENTINEL.

    Snapshot decisions are made by create_checkpoint in pregel (which has the step number) via is_snapshot_step. checkpoint() is only called for non-snapshot steps or when no checkpointer is available.
