Example 1 with GEOMETRY

use of com.facebook.presto.plugin.geospatial.GeometryType.GEOMETRY in project presto by prestodb.

the class TestSpatialJoinOperator method testYield.

@Test

    // create a filter function that yields for every probe match
    // verify we will yield #match times totally
    TaskContext taskContext = createTaskContext();
    DriverContext driverContext = taskContext.addPipelineContext(0, true, true, false).addDriverContext();
    // force a yield for every match
    AtomicInteger filterFunctionCalls = new AtomicInteger();
    InternalJoinFilterFunction filterFunction = new TestInternalJoinFilterFunction(((leftPosition, leftPage, rightPosition, rightPage) -> {
        filterFunctionCalls.incrementAndGet();
        driverContext.getYieldSignal().forceYieldForTesting();
        return true;
    }));

    PagesSpatialIndexFactory pagesSpatialIndexFactory = buildIndex(driverContext, (build, probe, r) -> build.contains(probe), Optional.empty(), Optional.of(filterFunction), buildPages);
    // 10 points in polygon A (x0...x9)
    // 10 points in polygons A and B (y0...y9)
    // 10 points in polygon B (z0...z9)
    // 40 total matches
    RowPagesBuilder probePages = rowPagesBuilder(ImmutableList.of(GEOMETRY, VARCHAR));
    for (int i = 0; i < 10; i++) {
        probePages.row(stPoint(1 + 0.1 * i, 1 + 0.1 * i), "x" + i);
    }

    }
    for (int i = 0; i < 10; i++) {
        probePages.row(stPoint(6 + 0.1 * i, 6 + 0.1 * i), "z" + i);
    }
    List<Page> probeInput = probePages.build();
    OperatorFactory joinOperatorFactory = new SpatialJoinOperatorFactory(2, new PlanNodeId("test"), INNER, probePages.getTypes(), Ints.asList(1), 0, Optional.empty(), pagesSpatialIndexFactory);
    Operator operator = joinOperatorFactory.createOperator(driverContext);
    assertTrue(operator.needsInput());
    operator.addInput(probeInput.get(0));
    operator.finish();
    // we will yield 40 times due to filterFunction
    for (int i = 0; i < 40; i++) {
        driverContext.getYieldSignal().setWithDelay(5 * SECONDS.toNanos(1), driverContext.getYieldExecutor());
        assertNull(operator.getOutput());
        assertEquals(filterFunctionCalls.get(), i + 1, "Expected join to stop processing (yield) after calling filter function once");
        driverContext.getYieldSignal().reset();
    }
    // delayed yield is not going to prevent operator from producing a page now (yield won't be forced because filter function won't be called anymore)
    driverContext.getYieldSignal().setWithDelay(5 * SECONDS.toNanos(1), driverContext.getYieldExecutor());
    Page output = operator.getOutput();
    assertNotNull(output);
    // make sure we have 40 matches
    assertEquals(output.getPositionCount(), 40);
}

Example 2 with GEOMETRY

use of com.facebook.presto.plugin.geospatial.GeometryType.GEOMETRY in project presto by prestodb.

the class AbstractTestGeoAggregationFunctions method assertAggregatedGeometries.

protected void assertAggregatedGeometries(String testDescription, String expectedWkt, String... wkts) {
    List<Slice> geometrySlices = Arrays.stream(wkts).map(text -> text == null ? null : OGCGeometry.fromText(text)).map(input -> input == null ? null : EsriGeometrySerde.serialize(input)).collect(Collectors.toList());
    // Add a custom equality assertion because the resulting geometry may have
    // its constituent points in a different order
    BiFunction<Object, Object, Boolean> equalityFunction = (left, right) -> {
        if (left == null && right == null) {
            return true;
        }
        if (left == null || right == null) {
            return false;
        }
        OGCGeometry leftGeometry = OGCGeometry.fromText(left.toString());
        OGCGeometry rightGeometry = OGCGeometry.fromText(right.toString());
        // Check for equality by getting the difference
        return leftGeometry.difference(rightGeometry).isEmpty() && rightGeometry.difference(leftGeometry).isEmpty();
    };
    // Test in forward and reverse order to verify that ordering doesn't affect the output
    assertAggregation(function, equalityFunction, testDescription, new Page(BlockAssertions.createSlicesBlock(geometrySlices)), expectedWkt);
    Collections.reverse(geometrySlices);
    assertAggregation(function, equalityFunction, testDescription, new Page(BlockAssertions.createSlicesBlock(geometrySlices)), expectedWkt);
