I would (kind of) agree with this point.. If you absolutely need performance here then python isn't the right choice. If, however, you are currently working with python and the question was just "why is pycassa not as fast as YCSB, can I make it faster" then I'd say the fact it was only a constant factor of 2 slower shows it's perfectly possible to stick with python. FYI the setup I'm using to write data to Cassandra is based around a series of 0mq applications - the actual loader is in python, but filtering steps before that are (partly) in C. Tim
