"Is the default 'auto' the best possible option so that no one has to worry about it anymore ?"
Yes something like that I guess. You can add the disk_access_mode property to your cassandra.yaml and set it to standard to disable memory mapped access, it will work. It's the same thing for the auto_bootstrap parameter and some other property like these two, they are not written in the conf anymore but still read if they exist.
