Michael Armbrust updated SPARK-17556:
-------------------------------------
Target Version/s: 2.3.0 (was: 2.2.0)
> Executor side broadcast for broadcast joins
> -------------------------------------------
>
> Key: SPARK-17556
> URL: https://issues.apache.org/jira/browse/SPARK-17556
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core, SQL
> Reporter: Reynold Xin
> Attachments: executor broadcast.pdf, executor-side-broadcast.pdf
>
>
> Currently in Spark SQL, in order to perform a broadcast join, the driver must
> collect the result of an RDD and then broadcast it. This introduces some
> extra latency. It might be possible to broadcast directly from executors.
