Constructor Detail

MergeInnerJoinIterator

public MergeInnerJoinIterator(org.spark_project.guava.collect.PeekingIterator<ExecRow> leftRS,
                              org.spark_project.guava.collect.PeekingIterator<ExecRow> rightRS,
                              int[] leftKeys,
                              int[] rightKeys,
                              JoinOperation mergeJoinOperation,
                              OperationContext<JoinOperation> operationContext)

MergeJoinRows constructor. Note that keys for left & right sides are the join keys on which each side is sorted (not all of the join keys).

Parameters:

leftRS - Iterator for left side rows

rightRS - Iterator for right side rows

leftKeys - Join key(s) on which left side is sorted

rightKeys - Join Key(s) on which right side is sorted

operationContext -
