PruneHiveTablePartitions Logical Optimization¶

PruneHiveTablePartitions is a logical optimization for partitioned Hive tables.

Creating Instance¶

PruneHiveTablePartitions takes the following to be created:

• SparkSession

PruneHiveTablePartitions is created when:

• HiveSessionStateBuilder is requested to customEarlyScanPushDownRules

updateTableMeta¶

updateTableMeta(
  relation: HiveTableRelation,
  prunedPartitions: Seq[CatalogTablePartition],
  partitionKeyFilters: ExpressionSet): CatalogTable

updateTableMeta...FIXME

updateTableMeta is used when:

• PruneHiveTablePartitions is executed (for a partitioned HiveTableRelation logical operator under a filter)
