Uses of Illustrable in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators

Classes in org.apache.pig.backend.hadoop.executionengine.physicalLayer.relationalOperators that implement Illustrable

Modifier and Type	Class and Description
class	CombinerPackager The package operator that packages the globally rearranged tuples into output format after the combiner stage.
class	JoinPackager
class	LitePackager This package operator is a specialization of POPackage operator used for the specific case of the order by query.
class	MultiQueryPackager The package operator that packages the globally rearranged tuples into output format as required by multi-query de-multiplexer.
class	Packager
class	POBroadcastSpark
class	POCollectedGroup The collected group operator is a special operator used when users give the hint 'using "collected"' in a group by clause.
class	POCounter This operator is part of the RANK operator implementation.
class	POCross Recover this class for nested cross operation.
class	PODemux The MapReduce Demultiplexer operator.
class	PODistinct Find the distinct set of tuples in a bag.
class	POFilter This is an implementation of the Filter operator.
class	POForEach
class	POFRJoin The operator models the join keys using the Local Rearrange operators which are configured with the plan specified by the user.
class	POFRJoinSpark
class	POGlobalRearrange Dummy operator to test MRCompiler.
class	POLimit
class	POLoad The load operator which is used in two ways: 1) As a local operator it can be used to load files 2) In the Map Reduce setting, it is used to create jobs from MapReduce operators which keep the loads and stores in the Map and Reduce Plans till the job is created
class	POLocalRearrange The local rearrange operator is a part of the co-group implementation.
class	POMergeCogroup
class	POMergeJoin This operator implements merge join algorithm to do map side joins.
class	PONative
class	POOptimizedForEach A specialized version of POForeach with the difference that in getNext(), it knows that "input" has already been attached by its input operator which SHOULD be POJoinPackage
class	POPackage The package operator that packages the globally rearranged tuples into output format as required by co-group.
class	POPartialAgg Do partial aggregation in map plan.
class	POPartitionRearrange The partition rearrange operator is a part of the skewed join implementation.
class	POPoissonSample
class	POPreCombinerLocalRearrange A specialized local rearrange operator which behaves like the regular local rearrange in the getNext() as far as getting its input and constructing the "key" out of the input.
class	PORank This operator is part of the RANK operator implementation.
class	POReservoirSample
class	POSkewedJoin The PhysicalOperator that represents a skewed join.
class	POSort This implementation is applicable for both the physical plan and for the local backend, as the conversion of physical to mapreduce would see the SORT operator and take necessary steps to convert it to a quantile and a sort job.
class	POSortedDistinct This operator is a variation of PODistinct, the input to this operator must be sorted already.
class	POSplit The MapReduce Split operator.
class	POStore The store operator which is used in two ways: 1) As a local operator it can be used to store files 2) In the Map Reduce setting, it is used to create jobs from MapReduce operators which keep the loads and stores in the Map and Reduce Plans till the job is created
class	POStream
class	POUnion The union operator that combines the two inputs into a single stream.
