DB Tsai updated SPARK-61100:
----------------------------
Fix Version/s: connect-rust-4.3.0
> Preserve tuple compatibility for Python Row objects
> ---------------------------------------------------
>
> Key: SPARK-61100
> URL: https://issues.apache.org/jira/browse/SPARK-61100
> Project: Spark
> Issue Type: Bug
> Components: Connect
> Affects Versions: connect-rust-4.3.0
> Reporter: DB Tsai
> Priority: Major
> Fix For: connect-rust-4.3.0
>
>
> Official PySpark Row is a tuple subclass. The Rust-backed Python Row is a
> native extension class, so isinstance(Row(a=1), tuple) is false and
> tuple-aware serializers such as json.dumps cannot encode it. Row.__fields__
> also returns a fresh list, so in-place mutation is lost. Preserve the public
> tuple Row contract for constructed, collected and nested rows, including
> pickle, equality/hash and field metadata, with regression tests. Measure the
> result-materialization tradeoff.
> Observed by source inspection of public apache/spark-connect-rust master
> 83d74462ec41012993176cf3af99017576688eb8. Runtime regression tests will
> accompany the fix.
