Dandandan opened a new issue #28: URL: https://github.com/apache/arrow-datafusion/issues/28
When the left side of the join is very small (compared to the right side) it is better to load the left side once(and broadcast it in Ballista). In DF this avoids hash partitioning, in Ballista this also avoids data shuffling. -- This is an automated message from the Apache Git Service.
