How to use mongodump for 1 collection
mongodb, mongodump
Solution
I think it's just:
mongodump --db=<old_db_name> --collection=<collection_name> --out=data/
mongorestore --db=<new_db_name> --collection=<collection_name> data/<db_name>/<collection_name>.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:"<old_db_name>.<collection_name>",to:"<new_db_name>.<collection_name>"})

Problem
How can I use `mongodump` to move a single collection from one database to another? How should I use the command and its options?
