-----------------------------------
Labels: pull-request-available (was: )
> Support user statistics visitor
> -------------------------------
>
> Key: SPARK-59850
> URL: https://issues.apache.org/jira/browse/SPARK-59850
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 4.1.3
> Reporter: Hongze Zhang
> Priority: Major
> Labels: pull-request-available
>
> Currently Spark only supports built-in statistics visitors in query planning.
> This makes Spark difficult to generate optimal query plan when 3rd SQL
> plugins are used, since SQL plugins might introduce custom expressions or
> execution backend with specialized statistics calculation.
> To address this, we can provide a registry and a configuration option to
> allow user to enable a custom statistics visitor.
