   Hi @AlexanderKaraberov 
   
   As you noticed already `io_priority` is used by `ioq` ([here](https://github.com/apache/couchdb-ioq/blob/master/src/ioq.erl#L110:L115)) to select appropriate requests queue. The bug fixed in this PR makes sure that `view_compact` requests go to the right queue. Database admin can influence which requests would have greater priority [see here](https://github.com/apache/couchdb-ioq/blob/master/src/ioq.erl#L139:L144).
