Unfortunately they aren’t quite as straight forward as single MongoDB command. All methods for renaming a database in MongoDB also take a fair amount of time and/or disk space to complete. Keep this in mind…

It can be very useful to enable logging in the MongoDB drivers to trace how the driver is interacting with the database.

I’m spending a lot of time in the MongoDB shell at the moment, so of course I went to see if someone had built an Emacs mode to support the MongoDB shell. Google very quickly pointed me at endofunky’s inf-mongo mode, which implements a basic shell interaction mode with MongoDB using comint. We have a winner, well, almost. The mode does exactly what it says on the tin, but I wanted a little more, namely being able to scroll through my command history. Other repl modes like Cider have…
