>
> Broadcast partitioning can not work with unaligned checkpointing. There
> are no guarantees that records are consumed at the same rate in all
> channels. This can result in some tasks applying state changes
> corresponding to a certain broadcasted event while others don't. In turn
> upon restore, it may lead to an inconsistent state.
