Labels: pull-request-available (was: )
> Support DSv2 Parquet shredded Variant predicate pushdown
> --------------------------------------------------------
>
> Key: SPARK-59020
> URL: https://issues.apache.org/jira/browse/SPARK-59020
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: EdisonWang
> Priority: Minor
> Labels: pull-request-available
>
> DSv2 Parquet filter pushdown currently runs before Variant extraction
> pushdown. Because of that ordering, filters on variant_get expressions are not
> translated into Parquet filters after the Variant extraction rewrite exposes
> the
> corresponding shredded fields.
> This change adds a narrow internal pushdown path for rewritten Variant
> predicate filters. V2 scan pushdown translates eligible rewritten filters
> after
> Variant extraction pushdown, ParquetScanBuilder records the accepted filters,
> and ParquetPartitionReaderFactory passes them to the existing ParquetFilters
> shredded Variant logic when the read schema contains shredded Variant
> metadata.
> The original Spark filters remain above the scan, so this only improves
> Parquet row-group skipping and does not change query results.
