> Adjust overhead of cached relation for DPP
> ------------------------------------------
>
> Key: SPARK-36735
> URL: https://issues.apache.org/jira/browse/SPARK-36735
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: L. C. Hsieh
> Priority: Major
>
> Currently we calculate if there is benefit of pruning with DPP by simply
> summing up the size of all scan relations as the overhead. However, for
> cached relations, the overhead should be different than a non-cached
> relation. This proposes to use adjusted overhead for cached relation with DPP.
