| Description |
|
With the new storage engines available in MongoDB 3.0, in order to switch from one storage engine you need to either mongodump/mongorestore or do an initial sync. Initial syncs copy collections and build indexes serially, which is incredibly slow. Like the new version of mongodump, initial syncs should be able to parallelize collections copies and index builds. |

dynamike, as Asya points out SERVER-18041 was opened to allow cloning collections in parallel, so I'm going to close this ticket as a duplicate. Please tune to SERVER-18041 for updates. Regards, |
