Examples with Functions io.crate.metadata.Functions used on opensource projects

Example 1 with Functions

use of io.crate.metadata.Functions in project crate by crate.

the class GroupingBytesRefCollectorBenchmark method createGroupingCollector.

@Setup
public void createGroupingCollector() {
    Functions functions = new ModulesBuilder().add(new AggregationImplModule()).createInjector().getInstance(Functions.class);
    groupByMinCollector = createGroupByMinBytesRefCollector(functions);
    List<BytesRef> keys = new ArrayList<>(Locale.getISOCountries().length);
    for (String s : Locale.getISOCountries()) {
        keys.add(new BytesRef(s));
    }
    rows = new ArrayList<>(20_000_000);
    for (int i = 0; i < 20_000_000; i++) {
        rows.add(new Row1(keys.get(i % keys.size())));
    }
}

Example 2 with Functions

use of io.crate.metadata.Functions in project crate by crate.

the class CurrentSchemaFunctionTest method testNormalizeCurrentSchemaCustomSchema.

@Test
public void testNormalizeCurrentSchemaCustomSchema() throws Exception {
    sqlExpressions = new SqlExpressions(tableSources, new SessionContext(0, Option.NONE, "custom_schema"));
    functions = sqlExpressions.getInstance(Functions.class);
    assertNormalize("current_schema()", isLiteral("custom_schema"), false);
}

Example 3 with Functions

use of io.crate.metadata.Functions in project crate by crate.

the class UnnestFunctionTest method prepareFunctions.

@Before
public void prepareFunctions() throws Exception {
    sqlExpressions = new SqlExpressions(ImmutableMap.of(QualifiedName.of("t"), mock(DocTableRelation.class)));
    functions = sqlExpressions.getInstance(Functions.class);
}

Example 4 with Functions

use of io.crate.metadata.Functions in project crate by crate.

the class SystemCollectSource method getCollector.

@Override
public CrateCollector getCollector(CollectPhase phase, BatchConsumer consumer, JobCollectContext jobCollectContext) {
    RoutedCollectPhase collectPhase = (RoutedCollectPhase) phase;
    // sys.operations can contain a _node column - these refs need to be normalized into literals
    EvaluatingNormalizer normalizer = new EvaluatingNormalizer(functions, RowGranularity.DOC, ReplaceMode.COPY, new NodeSysReferenceResolver(nodeSysExpression), null);
    final RoutedCollectPhase routedCollectPhase = collectPhase.normalize(normalizer, null);
    Map<String, Map<String, List<Integer>>> locations = collectPhase.routing().locations();
    String table = Iterables.getOnlyElement(locations.get(clusterService.localNode().getId()).keySet());
    Supplier<CompletableFuture<? extends Iterable<?>>> iterableGetter = iterableGetters.get(table);
    assert iterableGetter != null : "iterableGetter for " + table + " must exist";
    boolean requiresScroll = consumer.requiresScroll();
    return BatchIteratorCollectorBridge.newInstance(() -> iterableGetter.get().thenApply(dataIterable -> RowsBatchIterator.newInstance(dataIterableToRowsIterable(routedCollectPhase, requiresScroll, dataIterable), collectPhase.toCollect().size())), consumer);
}

Example 5 with Functions

use of io.crate.metadata.Functions in project crate by crate.

the class AggregateCollectorBenchmark method setup.

@Setup
public void setup() {
    InputCollectExpression inExpr0 = new InputCollectExpression(0);
    Functions functions = new ModulesBuilder().add(new AggregationImplModule()).createInjector().getInstance(Functions.class);
    SumAggregation<?> sumAggregation = (SumAggregation<?>) functions.getQualified(Signature.aggregate(SumAggregation.NAME, DataTypes.INTEGER.getTypeSignature(), DataTypes.LONG.getTypeSignature()), List.of(DataTypes.INTEGER), DataTypes.INTEGER);
    var memoryManager = new OnHeapMemoryManager(bytes -> {
    });
    collector = new AggregateCollector(Collections.singletonList(inExpr0), RamAccounting.NO_ACCOUNTING, memoryManager, Version.CURRENT, AggregateMode.ITER_FINAL, new AggregationFunction[] { sumAggregation }, Version.CURRENT, new Input[][] { { inExpr0 } }, new Input[] { Literal.BOOLEAN_TRUE });
