How to use mongodump for 1 collection

Question

How can I use mongodump to move a single collection from one database to another?

How should I use the command and its options?

Answer 1

I think it's just:

mongodump --db= --collection= --out=data/

mongorestore --db= --collection= data//.bson

Also see docs here and here.

Btw, the other way to move the collection from one database to another is to use renameCollection:

db.runCommand({renameCollection:".",to:"."})
