The correct Spark property to configure whether DataFrames below a certain size will be automatically broadcasted is spark.sql.autoBroadcastJoinThreshold. This property sets the size threshold for broadcasting tables during join operations. If a DataFrame is below this specified size, it will be broadcasted to all executor nodes to enhance the efficiency of the join operation.
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", value)
Sorry,its B, can't edit previous answer
This property is used to configure the threshold for automatically broadcasting small tables in join operations. When the size of a DataFrame is below this threshold, it will be broadcasted to all executor nodes for efficient join operations.
