Functions

func ComputePreviousCheckpointPath added in v0.16.0 

func ComputePreviousCheckpointPath(ctx context.Context, length int, nCtx handler.NodeExecutionContext, currentNodeUniqueID v1alpha1.NodeID, currentAttempt uint32) (storage.DataReference, error)

ComputePreviousCheckpointPath returns the checkpoint path for the previous attempt, if this is the first attempt then returns an empty path
