-/**
- * Prune hive table partitions using partition filters on
[[HiveTableRelation]]. The pruned
- * partitions will be kept in [[HiveTableRelation.prunedPartitions]], and the
statistics of
- * the hive table relation will be updated based on pruned partitions.
- *
- * This rule is executed in optimization phase, so the statistics can be
updated before physical
- * planning, which is useful for some spark strategy, eg.
- * [[org.apache.spark.sql.execution.SparkStrategies.JoinSelection]].
- *
- * TODO: merge this with PruneFileSourcePartitions after we completely make
hive as a data source.
