ExistenceJoinIterator

abstract class ExistenceJoinIterator extends Iterator[ColumnarBatch] with TaskAutoCloseableResource with Arm

Existence join generates an exists boolean column with true or false in it, then appends it to the output columns. The true in exists column indicates left table should retain that row, the row number of exists equals to the row number of left table.

e.g.: select * from left_table where left_table.column_0 >= 3 or exists (select * from right_table where left_table.column_1 < right_table.column_1) Explanation of this sql is: Filter(left_table.column_0 >= 3 or `exists`) Existence_join (left + `exists`) // `exists` do not shrink or expand the rows of left table left_table right_table

Abstract Value Members

  1. abstract def existsScatterMap(leftColumnarBatch: ColumnarBatch): GatherMap

    This method uses a left semijoin to construct a map of all indices into the left table batch pointing to rows that have a join partner on the right-hand side.

    This method uses a left semijoin to construct a map of all indices into the left table batch pointing to rows that have a join partner on the right-hand side.

    Given Boolean column FC totaling as many rows as leftColumnarBatch, all having the value "false", scattering "true" into column FC will produce the "exists" column of ExistenceJoin
