Examples with MultiplyByTwoOperatorFactory org.apache.flink.benchmark.operators.MultiplyByTwoOperatorFactory used on opensource projects

Example 1 with MultiplyByTwoOperatorFactory

use of org.apache.flink.benchmark.operators.MultiplyByTwoOperatorFactory in project flink-benchmarks by apache.

the class MultipleInputBenchmark method connectAndDiscard.

private static void connectAndDiscard(StreamExecutionEnvironment env, DataStream<?> source1, DataStream<?> source2) {
    MultipleInputTransformation<Long> transform = new MultipleInputTransformation<>("custom operator", new MultiplyByTwoOperatorFactory(), BasicTypeInfo.LONG_TYPE_INFO, 1);
    transform.addInput(source1.getTransformation());
    transform.addInput(source2.getTransformation());
    env.addOperator(transform);
    new MultipleConnectedStreams(env).transform(transform).addSink(new DiscardingSink<>());
}

Example 2 with MultiplyByTwoOperatorFactory

use of org.apache.flink.benchmark.operators.MultiplyByTwoOperatorFactory in project flink-benchmarks by apache.

the class MultipleInputBenchmark method multiInputChainedIdleSource.

@Benchmark
@OperationsPerInvocation(RECORDS_PER_INVOCATION)
public void multiInputChainedIdleSource(FlinkEnvironmentContext context) throws Exception {
    final StreamExecutionEnvironment env = context.env;
    env.getConfig().enableObjectReuse();
    final DataStream<Long> source1 = env.fromSource(new NumberSequenceSource(1L, RECORDS_PER_INVOCATION), WatermarkStrategy.noWatermarks(), "source-1");
    final DataStreamSource<Integer> source2 = env.fromSource(new IdlingSource(1), WatermarkStrategy.noWatermarks(), "source-2");
    MultipleInputTransformation<Long> transform = new MultipleInputTransformation<>("custom operator", new MultiplyByTwoOperatorFactory(), BasicTypeInfo.LONG_TYPE_INFO, 1);
    transform.addInput(((DataStream<?>) source1).getTransformation());
    transform.addInput(((DataStream<?>) source2).getTransformation());
    transform.setChainingStrategy(ChainingStrategy.HEAD_WITH_SOURCES);
    env.addOperator(transform);
    new MultipleConnectedStreams(env).transform(transform).addSink(new SinkClosingIdlingSource()).setParallelism(1);
    context.execute();
