Being a new user I apologise if this has been asked before (I had a quick search for previous forum posts but didn't find mention) or if it is a stupid question.
From what I understand, flush_all essentially invalidates all items in the caches on all nodes of a cluster. Is there a way to limit the use of flush_all? Perhaps restrict usage of the command with a password?
I'm finding it slightly concerning that the a webapp maybe able to flush_all contents of the cache without restriction, so, I am assuming that I must be missing something? This seems like giving a webapp user access to the drop table commands on a traditional database?
