Class StreamSelectTableSink

java.lang.Object

org.apache.flink.table.planner.sinks.SelectTableSinkBase<org.apache.flink.api.java.tuple.Tuple2<Boolean,org.apache.flink.table.data.RowData>>

org.apache.flink.table.planner.sinks.StreamSelectTableSink

All Implemented Interfaces:

org.apache.flink.table.sinks.RetractStreamTableSink<org.apache.flink.table.data.RowData>, org.apache.flink.table.sinks.StreamTableSink<org.apache.flink.api.java.tuple.Tuple2<Boolean,org.apache.flink.table.data.RowData>>, org.apache.flink.table.sinks.TableSink<org.apache.flink.api.java.tuple.Tuple2<Boolean,org.apache.flink.table.data.RowData>>

public class StreamSelectTableSink
extends SelectTableSinkBase<org.apache.flink.api.java.tuple.Tuple2<Boolean,org.apache.flink.table.data.RowData>>
implements org.apache.flink.table.sinks.RetractStreamTableSink<org.apache.flink.table.data.RowData>

A RetractStreamTableSink for streaming select job to collect the result to local.

RowData contains RowKind attribute which can represents all kind of changes. The boolean flag is useless here, only because RetractStreamTableSink requires Tuple2<Boolean, T> type.
