>                 Key: SPARK-3132
>                 URL: https://issues.apache.org/jira/browse/SPARK-3132
>             Project: Spark
>          Issue Type: Sub-task
>          Components: Spark Core
>            Reporter: Reynold Xin

> 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.
