>  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.
