Summary: Apply size-based optimization to planning
BroadcastNestedLoopJoin
Key: SPARK-2436
URL: https://issues.apache.org/jira/browse/SPARK-2436
Project: Spark
Issue Type: New Feature
Components: SQL
Reporter: Zongheng Yang
We should estimate the sizes of both the left side & right side, and make the
smaller one the broadcast relation.
As part of this task, BroadcastNestedLoopJoin needs to be slightly refactored
to take a BuildSide into account.
