Spark 3.0 Features | Dynamic Partition Pruning (DPP) | Avoid Scanning Irrelevant Data
Spark 3.0 has introduced multiple optimization features. Dynamic Partition Pruning (DPP) is one among them, which is an optimization on Star schema queries(data warehouse architecture model). DPP is implemented using Broadcast hashing technique for passing the subquery results of dimension table to fact table before loading the complete data into memory.
