Thanks Robert, Can you please explain what problems DROP/CREATE keyspace may cause? Seems like truncate working per column family and I have up to 10. What I should I delete from disk in that case? I can't delete whole folder right? I need to delete all content under each cf folder, but not folders? Correct?
