Example 1 with BytesRefColumnReference

use of io.crate.expression.reference.doc.lucene.BytesRefColumnReference in project crate by crate.

the class DocValuesGroupByOptimizedIteratorTest method test_group_by_doc_values_optimized_iterator_for_many_keys.

@Test
public void test_group_by_doc_values_optimized_iterator_for_many_keys() throws Exception {
    SumAggregation<?> sumAggregation = (SumAggregation<?>) functions.getQualified(Signature.aggregate(SumAggregation.NAME, DataTypes.LONG.getTypeSignature(), DataTypes.LONG.getTypeSignature()), List.of(DataTypes.LONG), DataTypes.LONG);
    var sumDocValuesAggregator = sumAggregation.getDocValueAggregator(List.of(new Reference(new ReferenceIdent(RelationName.fromIndexName("test"), "z"), RowGranularity.DOC, DataTypes.LONG, ColumnPolicy.DYNAMIC, IndexType.PLAIN, true, true, 0, null)), mock(DocTableInfo.class), List.of());
    var keyExpressions = List.of(new BytesRefColumnReference("x"), new LongColumnReference("y"));

    var it = DocValuesGroupByOptimizedIterator.GroupByIterator.forManyKeys(List.of(sumDocValuesAggregator), indexSearcher, keyRefs, keyExpressions, RamAccounting.NO_ACCOUNTING, null, null, new MatchAllDocsQuery(), new CollectorContext());
    var rowConsumer = new TestingRowConsumer();
    rowConsumer.accept(it, null);
    assertThat(rowConsumer.getResult(), containsInAnyOrder(new Object[] { "0", 0L, 6L }, new Object[] { "1", 1L, 4L }));
}

Example 2 with BytesRefColumnReference

use of io.crate.expression.reference.doc.lucene.BytesRefColumnReference in project crate by crate.

the class StringColumnReferenceTest method testFieldCacheExpression.

@Test
public void testFieldCacheExpression() throws Exception {
    BytesRefColumnReference bytesRefColumn = new BytesRefColumnReference(column);
    bytesRefColumn.startCollect(ctx);
    bytesRefColumn.setNextReader(new ReaderContext(readerContext));
