Ekaterina Dimitrova commented on CASSANDRA-15234: ------------------------------------------------- Thanks [~benedict] for the confirmation on what you had in mind here. Makes sense to me. So just to confirm I am not doing something stupid. For the backward compatibility we are simply using either the old or new parameter from yaml in Config/SysProperties, depending on which one the user used there? In the Database Descriptor I will add a warning which will also warn the developers that they can already use the new one. How about that? Or something else is meant in this case for backward compatibility? I already created a class of accessors for the SystemProperties. Just want to think also maybe about some of the environment variables too. The config is reshuffled and many renames are already in place so I guess after this confirmation and a couple of other things to complete, I will submit soon the commits for review.
