How to join two large tables in Spark?



Hi, Can anyone has an idea how to join two large tables in Spark where one table is having 2TB while other is having 5TB. Thru internet I come to know that “broadcast join” is good for joining two large tables considering one will be larger and other will be smaller, but didn’t get any info on size of smaller table data size. It is been common interview question that is facing often. Can anyone give an idea about it asap.
