fix: date_part sub-second parts and result nullability, reusing arrow kernels by mbutrovich · Pull Request #26686 · apache/datafusion

mbutrovich · 2026-10-23T21:32:46Z

Which issue does this PR close?

Closes EXTRACT(NANOSECOND) on Duration and Interval counts whole seconds twice #26678.
Closes date_part returning wrong results due to overflows #14738.
Closes date_part declares a non-nullable result for non-null input, but can return NULL #26685.

Rationale for this change

These fixes depend on each other. #26678 and #14738 come from the same NULL-as-zero branch. Fixing #14738 makes millisecond and microsecond of a long duration return NULL instead of a wrapped value. Without the #26685 fix, that NULL fails with declared as non-nullable on a non-nullable input, so fixing #14738 alone would replace a wrong result with an error.

What changes are included in this PR?

millisecond, microsecond and nanosecond share one function that reuses arrow's date_part and cast where they compute the right value.
A value that overflows the return type is NULL, as arrow already does for durations. Should overflow be an error instead? That would change other parts too, so I'd rather do it separately.
The integer parts of date_part and the Spark date_part are always nullable. epoch keeps the input's nullability.
The first commit (c920a5b) adds benchmark cases without the fix, so the benchmark bot can compare against it.

The benchmark bot measured Duration and Interval at 3.6x to 41.6x faster, times at 1.5x to 2.2x, and timestamps within noise.

Numbers

Speedups over c920a5b (the bench commit) on 1000 rows, with the bot's thin LTO. "Nulls" means 10% of rows are NULL. The aligned runs add -align-all-functions=6 -align-all-nofallthru-blocks=6.

Case	Neoverse-V2	aligned	Xeon 8581C	aligned
`nanosecond`, `Duration(ns)`, large values	28.73x	29.06x	29.10x	26.71x
`nanosecond`, `Duration(ns)`, large values, nulls	32.18x	32.41x	41.62x	36.13x
`nanosecond`, `Duration(ns)`, under 2.1 s	9.25x	9.41x	9.76x	8.99x
`nanosecond`, `Interval(DayTime)`	9.74x	9.60x	6.20x	5.97x
`nanosecond`, `Interval(MonthDayNano)`	6.53x	6.48x	8.72x	7.55x
`millisecond`, `Interval(DayTime)`	9.22x	9.61x	8.29x	7.96x
`microsecond`, `Duration(ns)`, under 2.1 s	5.16x	5.38x	3.64x	3.50x
`microsecond`, `Time64(ns)`	2.18x	2.24x	1.53x	1.61x
`millisecond`, `Timestamp(ns)`	1.11x	1.12x	1.08x	1.07x
`nanosecond`, `Timestamp(ns)` (unchanged)	0.99x	1.00x	0.98x	1.00x
`second`, `Timestamp(ns)` (unchanged)	1.00x	1.00x	1.00x	1.06x

In the default Xeon run the unchanged second cases are 0.98x to 1.08x, so gains in that range on timestamps are noise.

What is the testing strategy for this PR?

New cases in datafusion/sqllogictest/test_files/datetime/date_part.slt.
A unit test in datafusion/functions/src/datetime/date_part.rs.
A unit test in datafusion/spark/src/function/datetime/date_part.rs.

Are there any user-facing changes?

EXTRACT(MILLISECOND/MICROSECOND/NANOSECOND) on Duration and Interval return correct results. A Duration whose total in the requested unit overflows the return type returns NULL, as the other Duration parts already do, instead of a wrapped value or a panic. The integer results of date_part and the Spark date_part are nullable even for non-null input. There are no public API changes.
