ASF GitHub Bot updated SPARK-53928:
-----------------------------------
Labels: pull-request-available (was: )
> Enhance DSV2 partition filtering using catalyst expression
> ----------------------------------------------------------
>
> Key: SPARK-53928
> URL: https://issues.apache.org/jira/browse/SPARK-53928
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Szehon Ho
> Priority: Major
> Labels: pull-request-available
>
> Currently, Spark converts Catalyst Expression to either Filter or Predicate
> and pushes it to DSV2 via SupportsPushdownFilters and
> SupportsPushdownV2Filters API's.
> However, some Spark filters may not convert cleanly. For example,
> trim(part_col) = 'a'. There are cases where DSV2 can return the exact
> partition value(s) to spark for its InputPartition, and Spark can use the
> original catalyst expression for filtering.
