wanted know if there better way solve problem having. here flow: our client code understands protocol buffers (protobuf). on server side, our gateway gets protobuf , puts onto kafka. now avrò recommended encoding scheme, put specific protobuf within avro (as byte array) , put onto message bus. reason avoid having entire protobuf->avro conversion. on consumer side, reads avro message, gets protobuf out of , works on that. how reliable protobuf kafka? there lot of people using it? advantages/disadvantages of using kafka protobuf? is there better way handle our use case/scenario? thanks kafka doesn't differentiate between encoding schemes since @ end every message flows in , out of kafka binary . both proto-buff , avro binary based encoding schemes, why want wrap proto-buff inside avro schema, when can directly put proto-buff message kafka?
