Hi Mario I haven't come across ArangoDB, looks interesting thanks. It would be great to start experimenting with these things. As I think we've discussed during the hangouts, I think wiki.js could do with a bit of refactoring to make the tiddlers[] hashmap private so that it's easier to substitute a different storage module.
