Examples with NoopInputRowParser org.apache.druid.data.input.impl.NoopInputRowParser used on opensource projects

Example 1 with NoopInputRowParser

use of org.apache.druid.data.input.impl.NoopInputRowParser in project druid by druid-io.

the class StringColumnAggregationTest method setup.

@Before
public void setup() throws Exception {
    List<String> dimensions = ImmutableList.of(singleValue, multiValue);
    List<InputRow> inputRows = new ArrayList<>(n);
    for (int i = 1; i <= n; i++) {
        String val = String.valueOf(i * 1.0d);
        inputRows.add(new MapBasedInputRow(DateTime.now(DateTimeZone.UTC), dimensions, ImmutableMap.of(singleValue, val, multiValue, Lists.newArrayList(val, null, val))));
    }
    aggregationTestHelper = AggregationTestHelper.createGroupByQueryAggregationTestHelper(Collections.emptyList(), new GroupByQueryConfig(), tempFolder);
    IncrementalIndex index = AggregationTestHelper.createIncrementalIndex(inputRows.iterator(), new NoopInputRowParser(null), new AggregatorFactory[] { new CountAggregatorFactory("count") }, 0, Granularities.NONE, false, 100, false);
    this.segments = ImmutableList.of(new IncrementalIndexSegment(index, SegmentId.dummy("test")), aggregationTestHelper.persistIncrementalIndex(index, null));
    // we have ingested arithmetic progression from 1 to 10, so sums can be computed using following
    // All sum values are multiplied by 2 because we are running query on duplicated segment twice.
    numRows = 2 * n;
    singleValueSum = n * (n + 1);
    multiValueSum = 2 * n * (n + 1);
    singleValueMax = n;
    multiValueMax = n;
    singleValueMin = 1;
    multiValueMin = 1;
}

Example 2 with NoopInputRowParser

use of org.apache.druid.data.input.impl.NoopInputRowParser in project druid by druid-io.

the class SimpleTestIndex method makeRealtimeIndex.

private static IncrementalIndex makeRealtimeIndex() {
    try {
        List<InputRow> inputRows = Lists.newArrayListWithExpectedSize(NUM_ROWS);
        for (int i = 1; i <= NUM_ROWS; i++) {
            double doubleVal = i + 0.7d;
            String stringVal = String.valueOf(doubleVal);
            inputRows.add(new MapBasedInputRow(DateTime.now(DateTimeZone.UTC), DIMENSIONS, ImmutableMap.of(DOUBLE_COL, doubleVal, SINGLE_VALUE_DOUBLE_AS_STRING_DIM, stringVal, MULTI_VALUE_DOUBLE_AS_STRING_DIM, Lists.newArrayList(stringVal, null, stringVal))));
        }
        return AggregationTestHelper.createIncrementalIndex(inputRows.iterator(), new NoopInputRowParser(null), new AggregatorFactory[] { new CountAggregatorFactory("count"), new DoubleSumAggregatorFactory(DOUBLE_COL, DOUBLE_COL) }, 0, Granularities.NONE, false, 100, false);
    } catch (Exception ex) {
        throw new RuntimeException(ex);
    }
