Hello, Alexey. I just repeat our agreement to be on the same page
> The confirmation should only present in the user-facing interfaces. 1. We should add —force flag to the command.sh deactivation command. 2. We should throw the exception if cluster has in-memory caches and —force=false. 3. We shouldn’t change Java API for deactivation. Is it correct? > The DROP TABLE command does not have a "yes I am sure" clause in it I think it because the command itself has a «DROP» word in it’s name. Which clearly explains what will happen on it’s execution. On the opposite «deactivation» command doesn’t have any sign of destructive operation. That’s why we should warn user about it’s consequences. > 24 марта 2020 г., в 12:38, Alexey Goncharuk <alexey.goncha...@gmail.com> > написал(а): > > Igniters, Ivan, Nikolay, > > I am strongly against adding confirmation flags to any kind of APIs, > whether we change the deactivation behavior or not (even though I agree > that it makes sense to fix the deactivation to not clean up the in-memory > data).
