All Implemented Interfaces:

org.apache.calcite.plan.RelOptTable, org.apache.calcite.prepare.Prepare.PreparingTable, org.apache.calcite.schema.Wrapper, org.apache.calcite.sql.validate.SqlValidatorTable

public final class CatalogSourceTable
extends FlinkPreparingTableBase

A FlinkPreparingTableBase implementation which defines the interfaces required to translate the Calcite RelOptTable to the Flink specific TableSourceTable.

This table is only used to translate the CatalogTable into TableSourceTable during the last phase of the SQL-to-rel conversion, it is not necessary anymore once the SQL node was converted to a relational expression.

Constructor Detail

CatalogSourceTable

public CatalogSourceTable(org.apache.calcite.plan.RelOptSchema relOptSchema,
                          List<String> names,
                          org.apache.calcite.rel.type.RelDataType rowType,

Method Detail

createAnonymous

public static CatalogSourceTable createAnonymous(FlinkRelBuilder relBuilder,
                                                 org.apache.flink.table.catalog.ContextResolvedTable contextResolvedTable,
                                                 boolean isBatchMode)

Create a CatalogSourceTable from an anonymous ContextResolvedTable. This is required to manually create a preparing table skipping the calcite catalog resolution.

toRel

public org.apache.calcite.rel.RelNode toRel(org.apache.calcite.plan.RelOptTable.ToRelContext toRelContext)

Specified by:

toRel in interface org.apache.calcite.plan.RelOptTable

Overrides:

toRel in class FlinkPreparingTableBase

getCatalogTable

public org.apache.flink.table.catalog.CatalogTable getCatalogTable()
