Is the query stream also a Flink job? Is this use case not supported by keeping state within a single Flink job?

FLINK-3779 recently added "queryable state" to allow external processes access to operator state.

Hi Greg
My sink is a hashmap(acting as db store), I am reading from this hashmap
from other query stream. I need one instance / slot per task manager of
sink, so that everyone refers the same instance/slot.
So is there any way so that I can restrict 1 slot per task manager.

Thanks
