Example 1 with HelloRequestList

use of com.hazelcast.jet.grpc.greeter.GreeterOuterClass.HelloRequestList in project hazelcast by hazelcast.

the class GrpcServiceTest method when_repeatedBidirectionalStreaming.

@Test
public void when_repeatedBidirectionalStreaming() throws IOException {
    // Given
    server = createServer(new GreeterServiceImpl());
    final int port = server.getPort();
    List<String> items = IntStream.range(0, ITEM_COUNT).mapToObj(Integer::toString).collect(toList());
    Pipeline p = Pipeline.create();
    BatchStage<String> stage = p.readFrom(TestSources.items(items));
    // When
    BatchStage<String> mapped = stage.mapUsingServiceAsyncBatched(repeatedBidirectionalStreaming(port), 128, (service, itemList) -> {
        HelloRequestList req = HelloRequestList.newBuilder().addAllName(itemList).build();
        return service.call(req).thenApply(HelloReplyList::getMessageList);
    });
    // Then
    List<String> expected = IntStream.range(0, ITEM_COUNT).boxed().map(t -> "Hello " + Integer.toString(t)).collect(toList());
    mapped.writeTo(AssertionSinks.assertAnyOrder(expected));
    instance().getJet().newJob(p).join();
}

Example 2 with HelloRequestList

use of com.hazelcast.jet.grpc.greeter.GreeterOuterClass.HelloRequestList in project hazelcast by hazelcast.

the class GrpcServiceTest method when_repeatedBidirectionalStreaming_distributed.

@Test
public void when_repeatedBidirectionalStreaming_distributed() throws IOException {
    // Given
    server = createServer(new GreeterServiceImpl());
    final int port = server.getPort();
    List<String> items = IntStream.range(0, ITEM_COUNT).mapToObj(Integer::toString).collect(toList());
    Pipeline p = Pipeline.create();
    BatchStageWithKey<String, String> stage = p.readFrom(TestSources.items(items)).groupingKey(i -> i);
    // When
    BatchStage<String> mapped = stage.mapUsingServiceAsyncBatched(repeatedBidirectionalStreaming(port), 128, (service, itemList) -> {
        HelloRequestList req = HelloRequestList.newBuilder().addAllName(itemList).build();
        return service.call(req).thenApply(HelloReplyList::getMessageList);
    });
    // Then
    mapped.writeTo(AssertionSinks.assertCollected(e -> {
        assertEquals("unexpected number of items received", ITEM_COUNT, e.size());
    }));
    instance().getJet().newJob(p).join();
}
