---------------------------------
Issue Type: Sub-task (was: Bug)
Parent: SPARK-17129
> Partition pruning for metastore relation size estimates for better join
> selection.
> ----------------------------------------------------------------------------------
>
> Key: SPARK-16669
> URL: https://issues.apache.org/jira/browse/SPARK-16669
> Project: Spark
> Issue Type: Sub-task
> 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.
