[~davies], I'm assigning this to you since the PySpark broadcast changes that
we discussed sound very similar to this.
> Avoid serialization for Array[Byte] in TorrentBroadcast
> -------------------------------------------------------
>
> Key: SPARK-3132
> URL: https://issues.apache.org/jira/browse/SPARK-3132
> Project: Spark
> Issue Type: Sub-task
> Reporter: Reynold Xin
> Assignee: Davies Liu
>
> If the input data is a byte array, we should allow TorrentBroadcast to skip
> serializing and compressing the input.
> To do this, we should add a new parameter (shortCircuitByteArray) to
> TorrentBroadcast, and then avoid serialization in if the input is byte array
> and shortCircuitByteArray is true.
> We should then also do compression in task serialization itself instead of
> doing it in TorrentBroadcast.
