Github user uce commented on the pull request: https://github.com/apache/flink/pull/290#issuecomment-69917694 Nice :-) Regarding the DataInputDeserializer: You are right that it is currently not used, but I think with off-heap memory enabled the buffers will always be copied to a heap byte array, no? That's why I mentioned it. --- Did you run the integration tests manually or did you also implement the idea of randomly choosing on/off-heap memory for the integration tests?
