All Implemented Interfaces:

java.lang.Cloneable, BeamRelNode, org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.plan.RelOptNode, org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.rel.RelNode

public class BeamCoGBKJoinRel
extends BeamJoinRel

A BeamJoinRel which does CoGBK Join

This Join Covers the cases:

• BoundedTable JOIN BoundedTable
• UnboundedTable JOIN UnboundedTable

A CoGBK join is utilized as long as the windowFn of the both sides match. For more info refer BEAM-3345

General constraints:

• Only equi-join is supported.
• CROSS JOIN is not supported.
