Hi, what is the best message format to use with apachhe kafka so that producers and consumers can define contract and validate data and serialize/deserialize data? for example in xml we have xsd. but in json there is no universal schema.. i read about using apache avro but not sure how fast will it be as i can't afford more then 5 to 6 ms for schema validation and deserialisation? any inputs please? We will be processing thousands of transactions per second and SLA for each transaction is 150ms so i am looking for something that's very fast. Regards,Rohit
