From c1a81b47a2bcc2006d673955c1ff32e83edb2c0c Mon Sep 17 00:00:00 2001 From: Joe Isaacs Date: Mon, 14 Sep 2026 14:34:09 +0000 Subject: [PATCH 1/3] Push date bounds that DuckDB widened to TIMESTAMP `date '1993-07-01' + interval '3' month` returns a TIMESTAMP, so DuckDB widens the column side to match and the predicate binds as `CAST(o_orderdate AS TIMESTAMP) < TIMESTAMP '1993-10-01 00:00:00'`. The cast hides the column reference, so `can_push_expression` refused it and the bound stayed in a FILTER above the scan. TPC-H q4, q15 and q20 each pushed only their lower date bound, leaving the scan to emit 77%, 42% and 71% of the table where the full range keeps 3.8%, 3.6% and 14.5%. Fold the cast into the literal instead of evaluating it. The cast is strictly increasing, so the comparison has an exact DATE equivalent: at midnight the operator carries over unchanged, and strictly inside a day both `<` and `<=` admit that day while both `>` and `>=` exclude it. Keeping the predicate as `column literal` is the point -- that form prunes with statistics, which evaluating a cast per batch would not. Deliberately left alone: TIMESTAMP WITH TIME ZONE, whose cast depends on the session timezone; TRY_CAST, which yields NULL where CAST errors; and `=`/`<>` against a bound inside a day, where folding to a constant would drop the null cases. `can_push_cast` is unchanged, so a bare cast still does not push. Only the comparison shape is rewritten.

The cause is not the scan: once the upper bound pushes, `orders` has no filter left above it, so DuckDB's Deliminator collapses the delim join into a plain semi-join. That is the regression `pushdown_complex_filter` already documents for equality filters (duckdb/duckdb#22669); the existing hack just did not cover a `Lt`. Report a folded date bound as not pushed for the same reason. DuckDB then keeps its own copy of the predicate and its plan shape, while the bound still runs inside the scan, which is where the pruning comes from. Measured at sf=1, vortex-file-compressed, median of 10 iterations, 3 interleaved rounds against the same baseline: q4 97.1 -> 88.2 ms (0.91x, was 1.46x before this commit) q15 55.7 -> 42.5 ms (0.76x) q20 106.5 -> 80.2 ms (0.75x) The other 19 queries stay within run-to-run noise and the total moves 0.99x, which matches the plan regeneration touching only these three. Also drop the plan assertions from the e2e test. On a small single-table scan DuckDB converts these bounds into table filters itself without reaching the fold, so those assertions passed whether or not the fold existed. The test now pins semantics against native DuckDB as the oracle, and the checked-in TPC-H plans carry the proof that the bound reaches the scan.

That was the limitation this branch removes, so the assertion inverts. CI caught this and I did not: the earlier runs here filtered the suite to `-- tpch`, which never loaded the file. The full suite is 1 of 8394 tests, and this was it. Add the matching negative case while here: under a non-UTC session timezone a TIMESTAMPTZ bound must stay above the scan, and still return the same rows. That pairs a real exclusion check with the positive one, which the timezone cases in the Rust test could not do on their own. Correct the claim in date_pushdown_test's module docs that a plan assertion on a single-table scan would be vacuous. It is not: the FILTER node is present before this branch and absent after, which is exactly what cast_pushdown.slt keys on. The Rust test keeps the operator and boundary matrix against native DuckDB; the plan assertions live in the slt files, and the docs now say so.
