Example 1 with TestInMemoryStore

use of org.apache.samza.operators.impl.store.TestInMemoryStore in project samza by apache.

the class TestJoinOperator method createStreamOperatorTask.

private StreamOperatorTask createStreamOperatorTask(Clock clock, StreamApplicationDescriptorImpl graphSpec) throws Exception {
    Map<String, String> mapConfig = new HashMap<>();
    mapConfig.put("job.name", "jobName");
    mapConfig.put("job.id", "jobId");
    StreamTestUtils.addStreamConfigs(mapConfig, "inStream", "insystem", "instream");
    StreamTestUtils.addStreamConfigs(mapConfig, "inStream2", "insystem", "instream2");
    Context context = new MockContext(new MapConfig(mapConfig));
    TaskModel taskModel = mock(TaskModel.class);
    when(taskModel.getSystemStreamPartitions()).thenReturn(ImmutableSet.of(new SystemStreamPartition("insystem", "instream", new Partition(0)), new SystemStreamPartition("insystem", "instream2", new Partition(0))));
    when(context.getTaskContext().getTaskModel()).thenReturn(taskModel);
    when(context.getTaskContext().getTaskMetricsRegistry()).thenReturn(new MetricsRegistryMap());
    when(context.getContainerContext().getContainerMetricsRegistry()).thenReturn(new MetricsRegistryMap());
    // need to return different stores for left and right side
    IntegerSerde integerSerde = new IntegerSerde();
    TimestampedValueSerde timestampedValueSerde = new TimestampedValueSerde(new KVSerde(integerSerde, integerSerde));
    when(context.getTaskContext().getStore(eq("jobName-jobId-join-j1-L"))).thenReturn(new TestInMemoryStore(integerSerde, timestampedValueSerde));
    when(context.getTaskContext().getStore(eq("jobName-jobId-join-j1-R"))).thenReturn(new TestInMemoryStore(integerSerde, timestampedValueSerde));
    StreamOperatorTask sot = new StreamOperatorTask(graphSpec.getOperatorSpecGraph(), clock);
    sot.init(context);
    return sot;
}

Example 2 with TestInMemoryStore

use of org.apache.samza.operators.impl.store.TestInMemoryStore in project samza by apache.

the class TestWindowOperator method testTumblingAggregatingWindowsDiscardingMode.

@Test
public void testTumblingAggregatingWindowsDiscardingMode() throws Exception {
    when(this.context.getTaskContext().getStore("jobName-jobId-window-w1")).thenReturn(new TestInMemoryStore<>(new TimeSeriesKeySerde(new IntegerSerde()), new IntegerSerde()));
    OperatorSpecGraph sgb = this.getAggregateTumblingWindowStreamGraph(AccumulationMode.DISCARDING, Duration.ofSeconds(1), Triggers.repeat(Triggers.count(2))).getOperatorSpecGraph();
    List<WindowPane<Integer, Integer>> windowPanes = new ArrayList<>();
    TestClock testClock = new TestClock();
    StreamOperatorTask task = new StreamOperatorTask(sgb, testClock);
    task.init(this.context);
    MessageCollector messageCollector = envelope -> windowPanes.add((WindowPane<Integer, Integer>) envelope.getMessage());
    integers.forEach(n -> task.processAsync(new IntegerEnvelope(n), messageCollector, taskCoordinator, taskCallback));
    testClock.advanceTime(Duration.ofSeconds(1));
    task.window(messageCollector, taskCoordinator);
    Assert.assertEquals(windowPanes.size(), 5);
    Assert.assertEquals(windowPanes.get(0).getMessage(), new Integer(2));
    Assert.assertEquals(windowPanes.get(1).getMessage(), new Integer(2));
    Assert.assertEquals(windowPanes.get(2).getMessage(), new Integer(2));
    Assert.assertEquals(windowPanes.get(3).getMessage(), new Integer(2));
