For administration purposes it would be of great if you can easily rename a MongoDB collection with the help of shell command. |

This seems to be missing in Mongoid 5 – I used to be able to do: Mongoid::Sessions.default[:servers].rename(:agents) But I cannot find any way to do this any more? |

Ok, I've implemented fast renaming. |

I can take a look next week to see how long it'll take. Probably not more than a day. |

can you make an efficient rename within a db? or is that a huge project? |

I believe there is already a 'rename' or 'renameCollection' command implemented, however it makes a completely new copy of a collection and then deletes the old copy which could be considered inefficient. Also, there may not be a convenient shell wrapper. |
