Class Summary

Class	Description
BufferedVectorizedRowBatch	This is a convenience VectorizedRowBatch to be used by VectorPTFGroupBatches.
VectorPTFEvaluatorAbstractAvg<T>
VectorPTFEvaluatorAbstractLeadLag
VectorPTFEvaluatorAbstractSum<T>
VectorPTFEvaluatorBase	This is the vector PTF evaluator base class.
VectorPTFEvaluatorBytesCountDistinct	Bytes (String) implementation for VectorPTFEvaluatorCountDistinct.
VectorPTFEvaluatorCount	This class evaluates count(column) for a PTF group.
VectorPTFEvaluatorCountDistinct	This class evaluates count(column) for a PTF group where a distinct keyword is applied to the partitioning column itself, e.g.: SELECT txt1, txt2, count(distinct txt1) over(partition by txt1) as n, count(distinct txt2) over(partition by txt2) as m FROM example; In this case, the framework is still supposed to ensure sorting on the key (let's say txt1 for the first Reducer stage), but the original VectorPTFEvaluatorCount is not aware that a distinct keyword was applied to the key column.
VectorPTFEvaluatorCountStar	This class evaluates count(*) for a PTF group.
VectorPTFEvaluatorDecimalAvg	This class evaluates HiveDecimal avg() for a PTF group.
VectorPTFEvaluatorDecimalCountDistinct	Double implementation for VectorPTFEvaluatorCountDistinct.
VectorPTFEvaluatorDecimalFirstValue	This class evaluates HiveDecimal first_value() for a PTF group.
VectorPTFEvaluatorDecimalLastValue	This class evaluates HiveDecimal last_value() for a PTF group.
VectorPTFEvaluatorDecimalMax	This class evaluates HiveDecimal max() for a PTF group.
VectorPTFEvaluatorDecimalMin	This class evaluates HiveDecimal min() for a PTF group.
VectorPTFEvaluatorDecimalSum	This class evaluates HiveDecimal sum() for a PTF group.
VectorPTFEvaluatorDenseRank	This class evaluates rank() for a PTF group.
VectorPTFEvaluatorDoubleAvg	This class evaluates double avg() for a PTF group.
VectorPTFEvaluatorDoubleCountDistinct	Double implementation for VectorPTFEvaluatorCountDistinct.
VectorPTFEvaluatorDoubleFirstValue	This class evaluates double first_value() for a PTF group.
VectorPTFEvaluatorDoubleLastValue	This class evaluates double first_value() for a PTF group.
VectorPTFEvaluatorDoubleMax	This class evaluates double max() for a PTF group.
VectorPTFEvaluatorDoubleMin	This class evaluates double min() for a PTF group.
VectorPTFEvaluatorDoubleSum	This class evaluates double sum() for a PTF group.
VectorPTFEvaluatorHelper	VectorPTFEvaluatorHelper is a helper class for vector ptf operations.
VectorPTFEvaluatorLag
