سؤال
I have an existing MongoDB dump and I would like to cherry pick some of the data to a clean DB.
Is dumping a single collection and restoring them (mongodump & mongorestore) the way to do this?
المحلول
You can to this by using the --filter '<JSON>'
option on mongorestore
.
That's like the first argument of db.find()
.
If you just want to filter by collection --collection <collection>
See more info in the doc
