Hi there MongoDB Atlas is a great service that offers out of the box a lot of cluster management command that will be otherwise tricky to perform without a great knowledge of mongodb. Something that lacks in my opinion is related to disk management and especially when it comes to reclaim free space. In my experience occured that for this scenarios: * Usage of online archive functionality to move huge amount of data * Changes in the behavior of the application that relies on the cluster * Or a bug in the application Some collections (or the oplog) are left with a huge amount of free storage size that will be never used in the future: in this scenario only by manually performing the compact command it is possible to reclaim the free space, that should be used carefully in a production cluster. __In conclusion, in my opinion, it will be great te be able to perform the compact command on a collection by directly using MongoDB atlas (from the UI or automated mechanism)__
