This variable allows to set the maximum ingest occupancy — how busy ingest readers should be, in percentage, to start limiting query resources. If the maximum occupancy is less than the limit set, query permits i.e., query resources, will not be reduced. On the other hand, because the system always prioritizes getting data into the system, if the maximum occupancy is above this limit, then query resources are throttled.
