Does Mongodb checks for entries in Journals in find

Hi… I’m new to MongoDB…If there are some entries in Journals, and not yet written to the database, and if I do a find on that collection, will it look for entries in a journal too? or will it look just to the database, and return back…

If data from your collection has been written to the journal that means it has been written to memory and yes it will be available for reads. But as far as I know there is no way to directly query the journal, it’s purpose is mainly for data recovery during crashes.
