| celeborn.client.spark.shuffle.getReducerFileGroup.broadcast.enabled | false | false | Whether to leverage Spark broadcast mechanism to send the GetReducerFileGroupResponse. If the response size is large and Spark executor number is large, the Spark driver network may be exhausted because each executor will pull the response from the driver. With broadcasting GetReducerFileGroupResponse, it prevents the driver from being the bottleneck in sending out multiple copies of the GetReducerFileGroupResponse (one per executor). | 0.6.0 ||
