Re: Spark CBO
Hi, there is one cost-based analyzer implemented in Spark SQL, if I'm not mistaken, regarding the Join operations, If the join operation is done with a small dataset then Spark SQL's strategy will be to broadcast automatically the small dataset instead of shuffling. I guess you have something
