Question about artifact serialization -- suppose I have a flow that looks like the following:

class LinearFlow(FlowSpec):
    @step
    def start(self):
        self.next(self.a)

    @step
    def a(self):
        self.my_gigantic_var = 'xxx'
        self.next(self.b)

    @step
    def b(self):
        do_stuff(self.my_gigantic_var)
        self.next(self.end)

    @step
    def end(self):
        pass

Assuming step

b

does not modify

my_gigantic_var

, will

my_gigantic_var

be serialized as an artifact again when step

b

ends? As additional context, I noticed that my flow is getting OOM errors after

do_stuff

has completed, which I'm guessing is due to serializing the artifacts
