org.apache.beam.sdk.extensions.sql.impl.rule.BeamCoGBKJoinRule
public class BeamCoGBKJoinRule extends org.apache.beam.vendor.calcite.v1_28_0.org.apache.calcite.plan.RelOptRule
Rule to convert LogicalJoin node to BeamCoGBKJoinRel node.

This rule is matched when both the inputs to LogicalJoin node have the same Boundedness i.e. either when both the inputs are PCollection.IsBounded.BOUNDED or when both the inputs are PCollection.IsBounded.UNBOUNDED

As BeamSideInputLookupJoinRel also matches this condition when both the inputs are PCollection.IsBounded.BOUNDED, to avoid conflicts, this rule is not matched when any of the inputs to LogicalJoin node are Seekable.
