Hi, I have an older system (C* 2.1) using Thrift tables on which I want to alter a column composite. Right now it looks like (int, int, string) but I want it to be (int, int, string, string). Is it possible to do this on a live cluster without deleting the old data? Can you point me to some documentation about this? I can't seem to find it any more.
Best regards, Joel
