cloneCollection Command

Copy a single collection from one server to another.

db.runCommand( { cloneCollection: <namespace>,
                 from: <host> [,query: <query_filter>] [,copyIndexes:<bool>] } );

Copies a collection from one server to another. Do not use on a single server as the destination is placed at the same db.collection (namespace) as the source.

The local copy of the namespace is emptied before the copying begins. Any existing data will be lost there.
