org.apache.beam.sdk.extensions.sql.impl.rule.BeamSideInputJoinRule

public class BeamSideInputJoinRule
extends org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.plan.RelOptRule

Rule to convert LogicalJoin node to BeamSideInputJoinRel node.

This rule is matched when one of the input to LogicalJoin node is PCollection.IsBounded.BOUNDED and the other node is PCollection.IsBounded.UNBOUNDED

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