Examples with RTree org.apache.druid.collections.spatial.RTree used on opensource projects

Example 1 with RTree

use of org.apache.druid.collections.spatial.RTree in project druid by druid-io.

the class LinearGutmanSplitStrategyTest method testNumChildrenSizeRoaring.

@Test
public void testNumChildrenSizeRoaring() {
    BitmapFactory bf = new RoaringBitmapFactory();
    RTree tree = new RTree(2, new LinearGutmanSplitStrategy(0, 50, bf), bf);
    Random rand = ThreadLocalRandom.current();
    for (int i = 0; i < 100; i++) {
        tree.insert(new float[] { rand.nextFloat(), rand.nextFloat() }, i);
    }
    Assert.assertTrue(getNumPoints(tree.getRoot()) >= tree.getSize());
}

Example 2 with RTree
