I did some test by using createTypeInformation[MyClassToAnalyze] , it works
fine with some simple case class but will throw some "could not find
implicit value" or "constructor _UrlType in class _UrlType cannot be
accessed in <$anon:

Hi,
the serializers are created from TypeInformation. So you can simply
inspect the type information. E.g. by using this in the Scala API:
val typeInfo = createTypeInformation[MyClassToAnalyze]
And going through the object using a debugger.
Actually, I don't understand why scala.Tuple2 is tr
Actually the original source code have too many third part classes which is
hard to simplify , the question I want to ask is there any possible for me
to find out which is ser/dser by which Serializer class,then we can tuning
or and customer Serializer to improve performance.

Would you please give related code? I think it might due to insufficient hint
to type information.
