for example, TaggedFieldSerializer has settings readUnknownTagData and chunkedEncoding but it is not clear how to set these values in this library.

it would be great to have some example in README.

Many thanks!

You can pass a serializer factory instead of a serializer class to kryo: (see https://github.com/EsotericSoftware/kryo#serializer-factories)

TaggedFieldSerializerFactory defaultFactory = new TaggedFieldSerializerFactory();
defaultFactory.getConfig().setReadUnknownTagData(true);
kryo.setDefaultSerializer(defaultFactory);

I'll add a hint into the README.

Thanks!
but I can't figure out how to import the classes...

It looks like the Kryo documentation is outdated in this, I could not find the mentioned classes in their code base.

You could do this in preInit though:

kryo.getTaggedFieldSerializerConfig.setSkipUnknownTags(false)
kryo.setDefaultSerializer(classOf[TaggedFieldSerializer[_]])

The tagged field serializer is cloning this config upon creation.

@nvollmar thank you!
I'm using CompatibleFieldSerializer because I have issues with TaggedFieldSerializer.
