Apache Spark reassigned SPARK-30516:
------------------------------------
Assignee: (was: Apache Spark)
> statistic estimation of FileScan should take partitionFilters and partition
> number into account
> -----------------------------------------------------------------------------------------------
>
> Key: SPARK-30516
> URL: https://issues.apache.org/jira/browse/SPARK-30516
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Hu Fuwang
> Priority: Major
>
> Currently, FileScan.estimateStatistics does not take partitionFilters and
> partition number into account, which may lead to bigger sizeInBytes. It
> should be reasonable to change it to involve partitionFilters and partition
> number when estimating the statistics.
