I need to know how the MongoVUE "copy collection to different server" feature (right-click on a collection node and the option is available in the context menu) works. I want to compare it from a performance point of view to the mongodump/mongorestore option.
Does anybody know what shell commands MongoVUE issues behind the scenes? How does it stream data and which is the memory/disk space consumption during the process?
I was thinking about db.cloneCollection(), but in the docs they say
[It] does not allow you to clone a collection through a mongos. You must connect directly to the mongod instance.
which does not happen. My MongoVUE connections are tied to mongos ports.
