Review Comment:
> We can add a new rule before RepartitionBeforeWriting that changes the
dynamic partition write to static partition write.
But this may be a dangerous behavior, if inference errors will lead to data
errors, I think we can only control the behavior of Rebalance first, what do
you think?
