lamber-ken commented on issue #1352: [HUDI-625] Fixing performance issues around DiskBasedMap & kryo URL: https://github.com/apache/incubator-hudi/pull/1352#issuecomment-590706623 > classes extending BaseAvroPayload may be okay. but we allow users to implement their own payload classes.. if they don't have data converted as byte[], do we need to register them etc? It's right way to register the class to kryo, but if the custom payload doesn't have a no-arg constructor, it will not work. And, we already set the instantiator strategy, kryo built-in serializers have high performance. ``` kryo.setInstantiatorStrategy(new DefaultInstantiatorStrategy(new StdInstantiatorStrategy())); ```
