Example 1 with StringBitmapIndexColumnPartSupplier

use of org.apache.druid.segment.serde.StringBitmapIndexColumnPartSupplier in project druid by druid-io.

the class LikeFilterBenchmark method setup.

@Setup
public void setup() {
    step = (END_INT - START_INT) / cardinality;
    final BitmapFactory bitmapFactory = new RoaringBitmapFactory();
    final BitmapSerdeFactory serdeFactory = new RoaringBitmapSerdeFactory(null);
    final List<Integer> ints = generateInts();
    final GenericIndexed<String> dictionary = GenericIndexed.fromIterable(FluentIterable.from(ints).transform(new Function<Integer, String>() {

        @Override
        public String apply(Integer i) {
            return i.toString();
        }
    }), GenericIndexed.STRING_STRATEGY);
    final BitmapIndex bitmapIndex = new StringBitmapIndexColumnPartSupplier(bitmapFactory, GenericIndexed.fromIterable(FluentIterable.from(ints).transform(new Function<Integer, ImmutableBitmap>() {

        @Override
        public ImmutableBitmap apply(Integer i) {
            final MutableBitmap mutableBitmap = bitmapFactory.makeEmptyMutableBitmap();
            mutableBitmap.add((i - START_INT) / step);
            return bitmapFactory.makeImmutableBitmap(mutableBitmap);
        }
