From 605c6eda9001dbca79f77ba3357edd5419214cf3 Mon Sep 17 00:00:00 2001 From: Adrian Garcia Badaracco <1755071+adriangb@users.noreply.github.com> Date: Tue, 14 Apr 2026 09:20:52 -0500 Subject: [PATCH] Port filter_pushdown.rs async tests to sqllogictest Port 24 end-to-end filter-pushdown tests out of `datafusion/core/tests/physical_optimizer/filter_pushdown.rs` into the sqllogictest suite. The new `datafusion.explain.analyze_categories` session config lets `EXPLAIN ANALYZE` emit only deterministic metric categories ('rows'), so these tests can assert directly on the `predicate=DynamicFilter [ ... ]` text without `` scrubbing around timing/bytes. ## What moved New/extended tests in `datafusion/sqllogictest/test_files/push_down_filter_parquet.slt`: - TopK dynamic filter pushdown (single-col, multi-col sort, integration with max_row_group_size=128 and pushdown_rows_matched / pushdown_rows_pruned counters) - HashJoin CollectLeft dynamic filter with `struct(a, b) IN (SET)` shape - Nested hash joins (filter propagates to both inner scans) - Parent filter split across the two sides of a HashJoin - TopK above HashJoin (both dynamic filters ANDed on the probe scan) - Dynamic filter through a GROUP BY between HashJoin and probe scan - TopK projection rewrite (reorder, prune, expression, alias shadowing) - NULL-bearing build-side join keys - LEFT JOIN and LEFT SEMI JOIN dynamic filter pushdown - HashTable strategy (`hash_lookup`) via `hash_join_inlist_pushdown_max_size = 1` on both string and integer multi-column keys New tests in `datafusion/sqllogictest/test_files/push_down_filter_regression.slt`: - Aggregate dynamic filter baseline: MIN(a), MAX(a), MIN(a) + MAX(a), MIN(a) + MAX(b), mixed MIN/MAX with unsupported expression input, all-NULL input (filter stays `true`), MIN(a+1) (no filter emitted) - Filter on grouping column pushes through AggregateExec - Filter on aggregate result (HAVING count > 5) stays above the aggregate - End-to-end aggregate dynamic filter pruning a multi-file parquet scan ## What stayed in Rust Ten async tests were marked non-portable with a short comment explaining why. In short: they either hand-wire `PartitionMode::Partitioned` / `RepartitionExec` structures SQL never constructs, assert via debug APIs (`dynamic_filter_for_test()`, `apply_expressions` + `downcast_ref::`) that are not observable from SQL, or target the specific stacked-`FilterExec` shape that the logical optimizer collapses before physical planning.
