Avro schema doesn't honor backward compatibilty

Question

I have this avro schema

{
 \"namespace\": \"xx.xxxx.xxxxx.xxxxx\",
 \"type\": \"record\",
 \"name\": \"MyPayLoad\",
 \"fields\": [
     {\"name\": \"filed1\"         


        

Answer 1

finally i got this working. I need to give both the schemas in the SpecificDatumReader So i modified the parsing like this where i passed both the old and new schema in the reader and it worked like a charm

public static final MyPayLoad parseBinaryPayload(byte[] payload) {
        DatumReader payloadReader = new SpecificDatumReader<>(SCHEMA_V1, SCHEMA_V2);
        Decoder decoder = DecoderFactory.get().binaryDecoder(payload, null);
        MyPayLoad myPayLoad = null;
        try {
            myPayLoad = payloadReader.read(null, decoder);
        } catch (IOException e) {
            logger.log(Level.SEVERE, e.getMessage(), e);
        }

        return myPayLoad;
    }
