> Enable whole partition pruning for InMemoryTableScanExec
> --------------------------------------------------------
>
> Key: SPARK-17170
> URL: https://issues.apache.org/jira/browse/SPARK-17170
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Patrick Woody
>
> Currently InMemoryTableScanExec will prune cached batches executor side,
> possibly pruning the entire partition in the process. We should be able to
> leverage the same stats to determine if an entire partition can be removed up
> front and avoid launching a task.
