Examples with QueryCreatedEvent com.facebook.presto.spi.eventlistener.QueryCreatedEvent used on opensource projects

Example 1 with QueryCreatedEvent

use of com.facebook.presto.spi.eventlistener.QueryCreatedEvent in project presto by prestodb.

the class TestEventListener method testConstantQuery.

@Test
public void testConstantQuery() throws Exception {
    // QueryCreated: 1, QueryCompleted: 1, Splits: 1
    EventsBuilder events = generateEvents("SELECT 1", 3);
    QueryCreatedEvent queryCreatedEvent = getOnlyElement(events.getQueryCreatedEvents());
    assertEquals(queryCreatedEvent.getContext().getServerVersion(), "testversion");
    assertEquals(queryCreatedEvent.getContext().getServerAddress(), "127.0.0.1");
    assertEquals(queryCreatedEvent.getContext().getEnvironment(), "testing");
    assertEquals(queryCreatedEvent.getContext().getClientInfo().get(), "{\"clientVersion\":\"testVersion\"}");
    assertEquals(queryCreatedEvent.getMetadata().getQuery(), "SELECT 1");
    QueryCompletedEvent queryCompletedEvent = getOnlyElement(events.getQueryCompletedEvents());
    assertEquals(queryCompletedEvent.getStatistics().getTotalRows(), 0L);
    assertEquals(queryCompletedEvent.getContext().getClientInfo().get(), "{\"clientVersion\":\"testVersion\"}");
    assertEquals(queryCreatedEvent.getMetadata().getQueryId(), queryCompletedEvent.getMetadata().getQueryId());
    List<SplitCompletedEvent> splitCompletedEvents = events.getSplitCompletedEvents();
    assertEquals(splitCompletedEvents.get(0).getQueryId(), queryCompletedEvent.getMetadata().getQueryId());
    assertEquals(splitCompletedEvents.get(0).getStatistics().getCompletedPositions(), 1);
}

Example 2 with QueryCreatedEvent

use of com.facebook.presto.spi.eventlistener.QueryCreatedEvent in project presto by prestodb.

the class TestEventListener method testNormalQuery.

@Test
public void testNormalQuery() throws Exception {
    // We expect the following events
    // QueryCreated: 1, QueryCompleted: 1, Splits: SPLITS_PER_NODE (leaf splits) + LocalExchange[SINGLE] split + Aggregation/Output split
    int expectedEvents = 1 + 1 + SPLITS_PER_NODE + 1 + 1;
    EventsBuilder events = generateEvents("SELECT sum(linenumber) FROM lineitem", expectedEvents);
    QueryCreatedEvent queryCreatedEvent = getOnlyElement(events.getQueryCreatedEvents());
    assertEquals(queryCreatedEvent.getContext().getServerVersion(), "testversion");
    assertEquals(queryCreatedEvent.getContext().getServerAddress(), "127.0.0.1");
    assertEquals(queryCreatedEvent.getContext().getEnvironment(), "testing");

    QueryCompletedEvent queryCompletedEvent = getOnlyElement(events.getQueryCompletedEvents());
    assertEquals(queryCompletedEvent.getIoMetadata().getOutput(), Optional.empty());
    assertEquals(queryCompletedEvent.getIoMetadata().getInputs().size(), 1);
    assertEquals(queryCompletedEvent.getContext().getClientInfo().get(), "{\"clientVersion\":\"testVersion\"}");
    assertEquals(getOnlyElement(queryCompletedEvent.getIoMetadata().getInputs()).getConnectorId(), "tpch");
    assertEquals(queryCreatedEvent.getMetadata().getQueryId(), queryCompletedEvent.getMetadata().getQueryId());
    assertEquals(queryCompletedEvent.getStatistics().getCompletedSplits(), SPLITS_PER_NODE + 2);
    List<SplitCompletedEvent> splitCompletedEvents = events.getSplitCompletedEvents();
    // leaf splits + aggregation split
    assertEquals(splitCompletedEvents.size(), SPLITS_PER_NODE + 2);
    // All splits must have the same query ID
    Set<String> actual = splitCompletedEvents.stream().map(SplitCompletedEvent::getQueryId).collect(toSet());
    assertEquals(actual, ImmutableSet.of(queryCompletedEvent.getMetadata().getQueryId()));
    // Sum of row count processed by all leaf stages is equal to the number of rows in the table
    long actualCompletedPositions = splitCompletedEvents.stream().filter(// filter out the root stage
    e -> !e.getStageId().endsWith(".0")).mapToLong(e -> e.getStatistics().getCompletedPositions()).sum();
    MaterializedResult result = queryRunner.execute(session, "SELECT count(*) FROM lineitem");
    long expectedCompletedPositions = (long) result.getMaterializedRows().get(0).getField(0);
    assertEquals(actualCompletedPositions, expectedCompletedPositions);
    assertEquals(queryCompletedEvent.getStatistics().getTotalRows(), expectedCompletedPositions);
