> Avoid generic scalar probes for exact Python date inputs in Spark Connect Rust
> ------------------------------------------------------------------------------
>
> Key: SPARK-60685
> URL: https://issues.apache.org/jira/browse/SPARK-60685
> Project: Spark
> Issue Type: Improvement
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: DB Tsai
> Assignee: DB Tsai
> Priority: Major
> Labels: pull-request-available
> Fix For: connect-rust-4.3.0
>
>
> Frozen10k x3 date tuple input takes32.79ms in Rust vs1.66ms Python; pandas
> dates30.77ms vs1.79ms. py_to_value recognizes datetime.date only after
> Decimal/numeric/string/container checks and repeated datetime module lookup.
> Investigate a narrow exact datetime.date fast path preserving epoch days,
> valid range, date subclasses and datetime precedence. Keep
> subclasses/datetime/pandas Timestamp on existing semantics. This is distinct
> from exact numeric PR111 and borrowed Arrow input PR114. Require measured
> benefit and correctness at epoch/range boundaries before publishing.
