Review Comment:
> We can't judge the savepoint if be stored out of TTL.
Why can't? Doesn't it have TriggerTime? If triggerTime < current time - TTL,
it should be discarded, right?
> I‘m hesitating whether we should take savepoint as more important than
checkpoint.
I think it's more important due to it's triggered maunally. User might want
to use it.
