Example 6 with ClientAggregators

use of org.apache.phoenix.expression.aggregator.ClientAggregators in project phoenix by apache.

the class RowKeyOrderedAggregateResultIteratorTest method testSpanAll.

@Test
public void testSpanAll() throws Exception {
    Tuple[] results1 = new Tuple[] { new SingleKeyValueTuple(new KeyValue(B, SINGLE_COLUMN_FAMILY, SINGLE_COLUMN, Bytes.toBytes(2L))) };
    Tuple[] results2 = new Tuple[] { new SingleKeyValueTuple(new KeyValue(B, SINGLE_COLUMN_FAMILY, SINGLE_COLUMN, Bytes.toBytes(3L))) };
    Tuple[] results3 = new Tuple[] { new SingleKeyValueTuple(new KeyValue(B, SINGLE_COLUMN_FAMILY, SINGLE_COLUMN, Bytes.toBytes(4L))) };
    final List<PeekingResultIterator> results = Arrays.asList(new PeekingResultIterator[] { new MaterializedResultIterator(Arrays.asList(results1)), new MaterializedResultIterator(Arrays.asList(results2)), new MaterializedResultIterator(Arrays.asList(results3)) });
    ResultIterators iterators = new MaterializedResultIterators(results);
    Tuple[] expectedResults = new Tuple[] { new SingleKeyValueTuple(new KeyValue(B, SINGLE_COLUMN_FAMILY, SINGLE_COLUMN, Bytes.toBytes(9L))) };
    ClientAggregators aggregators = TestUtil.getSingleSumAggregator(getUrl(), PropertiesUtil.deepCopy(TestUtil.TEST_PROPERTIES));
    ResultIterator scanner = new RowKeyOrderedAggregateResultIterator(iterators, aggregators);
    AssertResults.assertResults(scanner, expectedResults);
}
