> According to {{get}} method doc in StateStore API, it returns non-null row if
> the key exists. So basically we should avoid write null to StateStore. You
> cannot distinguish if the returned null row is because the key doesn't exist,
> or the value is actually null. And due to the defined behavior of {{get}}, it
> is quite easy to cause NPE error if the caller doesn't expect to get a null
> if the caller believes the key exists.
