> Reduce the memory usage in file scan location metadata
> ------------------------------------------------------
>
> Key: SPARK-31793
> URL: https://issues.apache.org/jira/browse/SPARK-31793
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Gengliang Wang
> Assignee: Gengliang Wang
> Priority: Major
> Fix For: 3.1.0
>
>
> Currently, the data source scan node stores all the paths in its metadata.
> The metadata is kept when a SparkPlan is converted into SparkPlanInfo.
> SparkPlanInfo can be used to construct the Spark plan graph in UI.
> However, the paths can be very large (e.g. it can be many partitions after
> partition pruning), while UI pages only require up to 100 bytes for the
> location metadata. We can reduce the paths stored in metadata to reduce
> memory usage.
