Agreed. Thrift's progress has improved a lot since we first talked about using Avro RPC. In the meantime Avro RPC progress has slowed (the focus is on the Avro storage implementations). I think it'd be fair to give up on Avro RPC for client rpc for now*. It doesn't deliver enough over Thrift anymore. -ryan * I'm still a fan of using avro for data storage and anywhere else we currently do custom serialization
