    Description

      At present mongodump is capable of dumping multiple collection in parallel. However that feature does not help those users who need to dump a single large collection only. It would be nice if mongodump could take the advantage of parallelCollectionScan to fetch the collection's data from multiple cursors.

      It would make sense to use this option only if "--numParallelCollections==1.
