This isn't a thing in the project today, so anything exposed is now part of the public API. This is why I am harping on this topic as its been brought up... If you want tables/keyspaces where you can break w/e you wish, we need to *add* such a thing into the project, which I strongly do not feel this patch does. > I guess I'm fine with hiding it behind a property If we wish to hid the new progress log tables thats fine, but I am a hard -1 on hiding the existing tables as they were designed for operators / developers to help manage a production cluster. They are not "WE MAKE NO PROMISES EVER". -- This is an automated message from the Apache Git Service.
