Hi, my big mistake, I should have taken Avro::Protocol.parse instead of Avro::Schema, then it works to parse the protocol file
On the side: - in the -src distribution of cassandra you will have to run ant to find the cassandra.avpr in interfaces/avro Thanks for the hints, I've written a very small hello world script here to connect to cassandra via avro (in ruby) http://gist.github.com/570778 CU Christian
