I am really impressed with FoundationDB, so lately I’ve started working on a client for Scala. The goal is to create API that is type-safe and idiomatic for Scala: https://github.com/pwliwanow/foundationdb4s
ClassScheduling example from the docs, to give better understanding how using the library looks like (link to the Scala implementation: https://github.com/pwliwanow/foundationdb4s/blob/master/example/src/main/scala/com/github/pwliwanow/foundationdb4s/example/ClassScheduling.scala).
Of course not everything is yet implemented (but more functionalities are coming!), and if you have any suggestions please let me know or create an issue on GitHub.
