Sean Owen resolved SPARK-26214.
-------------------------------
Resolution: Won't Fix
> Add "broadcast" method to DataFrame
> -----------------------------------
>
> Key: SPARK-26214
> URL: https://issues.apache.org/jira/browse/SPARK-26214
> Project: Spark
> Issue Type: Wish
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Thomas Decaux
> Priority: Trivial
> Labels: broadcast, dataframe
>
> As discussed at
> [https://stackoverflow.com/questions/43984068/does-spark-sql-autobroadcastjointhreshold-work-for-joins-using-datasets-join-op/43994022,]
> it's possible to force broadcast of DataFrame, even if total size is greater
> than ``*spark.sql.autoBroadcastJoinThreshold``.*
> But this not trivial for beginner, because there is no "broadcast" method (I
> know, I am lazy ...).
> We could add this method, with a WARN if size is greater than the threshold.
> (if it's an easy one, I could do it?)
