Patrick Wendell updated SPARK-3917:
-----------------------------------
Priority: Major (was: Critical)
> Compress data before network transfer
> -------------------------------------
>
> Key: SPARK-3917
> URL: https://issues.apache.org/jira/browse/SPARK-3917
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.1.0
> Environment: All
> Reporter: junlong
> Fix For: 1.1.0
>
>
> When training Gradient Boosting Decision Tree on large sparse data, heavy
> network flow pull down CPU utilization ratio. And through compression on
> network flow data, 90% are reduced.
> So maybe compression before transfering may provide higher speedup on
> spark. And user can configure it to decide whether compress or not.
