> Add expression-level entry points to optimizer rules for the single-pass
> analyzer
> ---------------------------------------------------------------------------------

> Key: SPARK-58866
> URL: https://issues.apache.org/jira/browse/SPARK-58866
> Project: Spark
> Issue Type: Task
> Components: Optimizer
> Affects Versions: 4.4.0
> Reporter: Matvei Zamiatin
> Priority: Major
> Labels: pull-request-available
>
> The single-pass analyzer needs to run several optimizer rules on individual,
> freshly-resolved expression trees rather than on a whole LogicalPlan. For
> example, resolving a procedure CALL requires folding and rewriting its
> argument expressions (constant folding, With inlining, RuntimeReplaceable
> expansion, current date/time and current catalog/database substitution,
> special datetime values) before they are used.
> Today these rules only expose plan-level apply(plan: LogicalPlan) entry
> points. This ticket refactors them to also expose expression-level entry
> points by extracting the shared rewrite logic into partial functions, with no
> behavior change to the existing plan-level apply.
