> I can see that now we support queryable state, why don't we also support the writable
state? I've already done this on our own business to initialize the state in window during
the program's first run. I think other companies may have other needs to modify the state
from outside the job.
> The synchronization is a problem but from my perspective, very few objects will be affected
because we can directly operate on the stateTable(for the FsStateBackend), and about the performance,
I think it'll be okay if users know about it.
> I'm not very aware of what will be affected except what I said above, please let me know
more if anyone has doubt about this.
