Dynamic Partition Pruning (DPP) is an optimization of JOIN queries of partitioned tables using partition columns in a join condition.The idea is to push filter conditions down to the large fact table and reduce the number of rows to scan. In a Sort Merge Join partitions are sorted on the join key prior to the join operation. For almost all queries, Kubernetes and YARN queries finish in a +/- 10% range of the other. Broadcast joins happen when Spark decides to send a copy of a table to all the executor nodes.The intuition here is that, if we broadcast one of the datasets, Spark no longer needs an all-to-all communication strategy and each Executor will be self-sufficient in joining the big dataset . Manually tuning these parameters for optimized performance is not practical because the parameter tuning space is huge.
