    assertMergeHiveColumnStatistics(HiveColumnStatistics.builder().setDateStatistics(new DateStatistics(Optional.of(LocalDate.ofEpochDay(1)), Optional.of(LocalDate.ofEpochDay(2)))).build(), HiveColumnStatistics.builder().setDateStatistics(new DateStatistics(Optional.of(LocalDate.ofEpochDay(0)), Optional.of(LocalDate.ofEpochDay(3)))).build(), HiveColumnStatistics.builder().setDateStatistics(new DateStatistics(Optional.of(LocalDate.ofEpochDay(0)), Optional.of(LocalDate.ofEpochDay(3)))).build());
}

Example 2 with DateStatistics

use of io.trino.plugin.hive.metastore.DateStatistics in project trino by trinodb.

    DateColumnStatsData dateColumnStatsData = new DateColumnStatsData();
    dateColumnStatsData.setLowValue(new Date(1000));
    dateColumnStatsData.setHighValue(new Date(2000));

    dateColumnStatsData.setNumDVs(20);
    ColumnStatisticsObj columnStatisticsObj = new ColumnStatisticsObj("my_col", DATE_TYPE_NAME, dateStats(dateColumnStatsData));
    HiveColumnStatistics actual = fromMetastoreApiColumnStatistics(columnStatisticsObj, OptionalLong.of(1000));
    assertEquals(actual.getIntegerStatistics(), Optional.empty());
