Subject [GitHub] flink pull request: [FLINK-3140] NULL value data layout in Row Ser...

Github user tillrohrmann commented on the pull request:

    @aljoscha is absolutely right about the performance aspect. However, the key difference
is that he was referring in his comment to the implementation of the `serialize` method which
is extensively used and, thus, should be as efficient as possible.
    If I'm not mistaken, then this argument does not apply to the `createAuxiliaryFields`
method, though. The reason is that this method is called before the job is actually executed
and, consequently, should not have any impact on the runtime behaviour. But I might be wrong
here, since we're also shipping `TypeInformation` to the cluster, nowadays.
