java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.calcite.rel.core.Values

org.apache.beam.sdk.extensions.sql.impl.rel.BeamValuesRel

All Implemented Interfaces:

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

public class BeamValuesRel
extends org.apache.calcite.rel.core.Values
implements BeamRelNode

BeamRelNode to replace a Values node.

BeamValuesRel will be used in the following SQLs:

• insert into t (name, desc) values ('hello', 'world')
• select 1, '1', LOCALTIME
