Date Sat, 11 Apr 2015 22:03:48 GMT
Github user marmbrus commented on a diff in the pull request:
    --- Diff: sql/core/src/main/scala/org/apache/spark/sql/execution/SparkStrategies.scala
    @@ -90,6 +90,13 @@ private[sql] abstract class SparkStrategies extends QueryPlanner[SparkPlan]
                left.statistics.sizeInBytes <= sqlContext.conf.autoBroadcastJoinThreshold
               makeBroadcastHashJoin(leftKeys, rightKeys, left, right, condition, joins.BuildLeft)
    +      // for now let's support inner join first, then add outer join
    --- End diff --
    Lets explictly comment that we try SortMergeJoin first, but only if the config is set.
