Hi, As I'm still planning how to do to transport my data, I can use Thrift as well, but how does Thrift and Avro integrates? Avro seems very interesting to serialize data and also pretty straightforward (define a schema -> transform data -> read data again using the same schema). It's not clear to me the role of Thrift (ok it will generate code to make the RPC call) and the integration with Avro. Can you please add more details? Regards. Seba
