Hey FDB users, Is there any tools that people have developed to get an estimate of the size of key/value pairs in each directory? Use case here is that we have a shared FDB cluster where a bunch of different services use, with each service using a different directory. We’d like to get an estimate of the amount of space in the DB each service is using. ---

There is a [new api](https://github.com/apple/foundationdb/pull/2537) being introduced in 6.3 release that should help with that. Also, see the [release notes](https://github.com/apple/foundationdb/blob/master/documentation/sphinx/source/release-notes/release-notes-630.rst) for 6.3. ---

Wow suuuuper cool! This is exactly what I’m looking for. Can’t wait for the 6.3 release 🙂
