类 RichTableSourceQueryOperation<T>

java.lang.Object

org.apache.flink.table.operations.TableSourceQueryOperation<T>

org.apache.flink.table.planner.operations.RichTableSourceQueryOperation<T>

所有已实现的接口:

org.apache.flink.table.operations.Operation, org.apache.flink.table.operations.QueryOperation

@Internal
public class RichTableSourceQueryOperation<T>
extends org.apache.flink.table.operations.TableSourceQueryOperation<T>

A TableSourceQueryOperation with FlinkStatistic and qualifiedName. TODO this class should be deleted after unique key in TableSchema is ready and setting catalog statistic to TableSourceTable in DatabaseCalciteSchema is ready

This is only used for testing.
