Are you running with n=[number ops] or duration=[xx]? I’ve found you need to you n= when inserting data. When you use duration cassandra-stress defaults to 1,000,000 somethings (to be honest, I’m not entirely sure if it’s rows, partitions or something else that the 1,000,000 relates to) and running for a long time just results in overwriting a lot a data that gets compacted away. Using n=[number > 1M] will get you n somethings.
