> Partition pruning for metastore relation size estimates for better join

> Key: SPARK-16669
> URL: https://issues.apache.org/jira/browse/SPARK-16669
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Parth Brahmbhatt
>
> Currently the metastore statistics returns the size of entire table which
> results in Join selection strategy to not use broadcast joins even when only
> a single partition from a large table is selected. We should optimize the
> statistic calculation at table level to apply partition pruning and only get
> the size of Partition that are valid for the query.
