Example 1 with Utf8BloomFilterBuilder

use of io.trino.orc.metadata.statistics.Utf8BloomFilterBuilder in project trino by trinodb.

the class TestOrcBloomFilters method testMatchesExpandedRange.

@Test
public void testMatchesExpandedRange() {
    Range range = Range.range(BIGINT, 1233L, true, 1235L, true);
    TupleDomainOrcPredicate predicate = TupleDomainOrcPredicate.builder().setBloomFiltersEnabled(true).addColumn(ROOT_COLUMN, Domain.create(ValueSet.ofRanges(range), false)).setDomainCompactionThreshold(100).build();
    ColumnMetadata<ColumnStatistics> matchingStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, new Utf8BloomFilterBuilder(1000, 0.01).addLong(1234L).buildBloomFilter())));
    ColumnMetadata<ColumnStatistics> nonMatchingStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, new Utf8BloomFilterBuilder(1000, 0.01).addLong(9876L).buildBloomFilter())));
    assertTrue(predicate.matches(1L, matchingStatisticsByColumnIndex));
    assertFalse(predicate.matches(1L, nonMatchingStatisticsByColumnIndex));
}

Example 2 with Utf8BloomFilterBuilder

use of io.trino.orc.metadata.statistics.Utf8BloomFilterBuilder in project trino by trinodb.

the class TestOrcBloomFilters method testMatches.

@Test
public // simulate query on 2 columns where 1 is used as part of the where, with and without bloom filter
void testMatches() {
    TupleDomainOrcPredicate predicate = TupleDomainOrcPredicate.builder().setBloomFiltersEnabled(true).addColumn(ROOT_COLUMN, Domain.singleValue(BIGINT, 1234L)).build();
    TupleDomainOrcPredicate emptyPredicate = TupleDomainOrcPredicate.builder().build();
    ColumnMetadata<ColumnStatistics> matchingStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, new Utf8BloomFilterBuilder(1000, 0.01).addLong(1234L).buildBloomFilter())));
    ColumnMetadata<ColumnStatistics> nonMatchingStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, new Utf8BloomFilterBuilder(1000, 0.01).buildBloomFilter())));
    ColumnMetadata<ColumnStatistics> withoutBloomFilterStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, null)));
    assertTrue(predicate.matches(1L, matchingStatisticsByColumnIndex));
    assertTrue(predicate.matches(1L, withoutBloomFilterStatisticsByColumnIndex));
    assertFalse(predicate.matches(1L, nonMatchingStatisticsByColumnIndex));
    assertTrue(emptyPredicate.matches(1L, matchingStatisticsByColumnIndex));
}

Example 3 with Utf8BloomFilterBuilder

use of io.trino.orc.metadata.statistics.Utf8BloomFilterBuilder in project trino by trinodb.

the class TestOrcBloomFilters method testMatchesNonExpandedRange.

@Test
public void testMatchesNonExpandedRange() {
    ColumnMetadata<ColumnStatistics> matchingStatisticsByColumnIndex = new ColumnMetadata<>(ImmutableList.of(new ColumnStatistics(null, 0, null, new IntegerStatistics(10L, 2000L, null), null, null, null, null, null, null, new Utf8BloomFilterBuilder(1000, 0.01).addLong(1500L).buildBloomFilter())));
    Range range = Range.range(BIGINT, 1233L, true, 1235L, true);
    TupleDomainOrcPredicate.TupleDomainOrcPredicateBuilder builder = TupleDomainOrcPredicate.builder().setBloomFiltersEnabled(true).addColumn(ROOT_COLUMN, Domain.create(ValueSet.ofRanges(range), false));
    // Domain expansion doesn't take place -> no bloom filtering -> ranges overlap
    assertTrue(builder.setDomainCompactionThreshold(1).build().matches(1L, matchingStatisticsByColumnIndex));
    assertFalse(builder.setDomainCompactionThreshold(100).build().matches(1L, matchingStatisticsByColumnIndex));
