Uses of Transform in org.apache.hadoop.hive.ql.optimizer

Classes in org.apache.hadoop.hive.ql.optimizer that implement Transform

class	BucketingSortingReduceSinkOptimizer This transformation does optimization for enforcing bucketing and sorting.
class	BucketMapJoinOptimizer this transformation does bucket map join optimization.
class	ColumnPruner Implementation of one of the rule-based optimization steps.
class	GlobalLimitOptimizer This optimizer is used to reduce the input size for the query for queries which are specifying a limit.
class	GroupByOptimizer This transformation does group by optimization.
class	JoinReorder Implementation of rule-based join table reordering optimization.
class	LimitPushdownOptimizer Make RS calculate top-K selection for limit clause.
class	MapJoinProcessor Implementation of one of the rule-based map join optimization.
class	NonBlockingOpDeDupProc merges SEL-SEL or FIL-FIL into single operator
class	SamplePruner The transformation step that does sample pruning.
class	SimpleFetchAggregation
class	SimpleFetchOptimizer Tries to convert simple fetch query to single fetch task, which fetches rows directly from location of table/partition.
class	SkewJoinOptimizer SkewJoinOptimizer.
class	SortedDynPartitionOptimizer When dynamic partitioning (with or without bucketing and sorting) is enabled, this optimization sorts the records on partition, bucket and sort columns respectively before inserting records into the destination table.
class	SortedMergeBucketMapJoinOptimizer
class	StatsOptimizer There is a set of queries which can be answered entirely from statistics stored in metastore.
