Data Source API V2 supports filter pushdown performance optimization for DataSourceReaders with SupportsPushDownFilters (that is applied when DataSourceV2Strategy execution planning strategy is requested to plan a DataSourceV2Relation logical operator).
(From Parquet Filter Pushdown in Apache Drill’s documentation) Filter pushdown is a performance optimization that prunes extraneous data while reading from a data source to reduce the amount of data to scan and read for queries with supported filter expressions. Pruning data reduces the I/O, CPU, and network overhead to optimize query performance.
