Don't take my word for it, it's easy enough to fill up a small 3 node cluster and play with it. Here's a few more things that you should pay attention to: - If you change the schema you are obviously going to have to reconverge to the previous schema. - You want to avoid pending commitlog entries. If you want to load a full snapshot from scratch, the easiest route would be to drop the KS, recreate it with the expected schema and load your sstables from disk. >> If you don't want to take your whole cluster offline you can use >> sstableloader as well. > > Sounds wonderful.
