>
> Right now (after SOLR-5473 was committed), a node watches a collection only if stateFormat=1 or if that node hosts at least one core belonging to that collection.
> This means that a node which is the overseer operates on all collections but watches only a few. So any read goes directly to zookeeper which slows down overseer operations.
> Let's have the overseer node watch all collections always and never remove those watches (except when the collection itself is deleted).
