Example 1 with SinkUpsertMaterializer

use of org.apache.flink.table.runtime.operators.sink.SinkUpsertMaterializer in project flink by apache.

the class CommonExecSink method applyUpsertMaterialize.

private Transformation<RowData> applyUpsertMaterialize(Transformation<RowData> inputTransform, int[] primaryKeys, int sinkParallelism, ReadableConfig config, RowType physicalRowType) {
    GeneratedRecordEqualiser equaliser = new EqualiserCodeGenerator(physicalRowType).generateRecordEqualiser("SinkMaterializeEqualiser");
    SinkUpsertMaterializer operator = new SinkUpsertMaterializer(StateConfigUtil.createTtlConfig(config.get(ExecutionConfigOptions.IDLE_STATE_RETENTION).toMillis()), InternalSerializers.create(physicalRowType), equaliser);
    final String[] fieldNames = physicalRowType.getFieldNames().toArray(new String[0]);
    final List<String> pkFieldNames = Arrays.stream(primaryKeys).mapToObj(idx -> fieldNames[idx]).collect(Collectors.toList());
    OneInputTransformation<RowData, RowData> materializeTransform = ExecNodeUtil.createOneInputTransformation(inputTransform, createTransformationMeta(UPSERT_MATERIALIZE_TRANSFORMATION, String.format("SinkMaterializer(pk=[%s])", String.join(", ", pkFieldNames)), "SinkMaterializer", config), operator, inputTransform.getOutputType(), sinkParallelism);
    RowDataKeySelector keySelector = KeySelectorUtil.getRowDataSelector(primaryKeys, InternalTypeInfo.of(physicalRowType));
    materializeTransform.setStateKeySelector(keySelector);
    materializeTransform.setStateKeyType(keySelector.getProducedType());
    return materializeTransform;
}
