         * [ About PointMBR Optimization ]
         * Instead of storing a MBR(4 doubles) for a point(2 doubles) in RTree leaf node,
         * PointMBR concept is introduced.
         * PointMBR is a way to store a point as 2 doubles in RTree leaf node.
         * This reduces RTree index size roughly in half.
         * In order to fully benefit from the PointMBR concept, besides RTree,
         * external sort operator during bulk-loading (from either data loading or index creation)
         * must deal with point as 2 doubles instead of 4 doubles. Otherwise, external sort will suffer from twice as
         * many doubles as it actually requires. For this purpose,
         * PointMBR specific optimization logic is added as follows:
         * 1) CreateMBR function in assign operator generates 2 doubles, instead of 4 doubles.
         * 2) External sort operator sorts points represented with 2 doubles.
         * 3) Bulk-loading in RTree takes 4 doubles by reading 2 doubles twice and then,
         * do the same work as non-point MBR cases.

Example 10 with TreeIndexBulkLoadOperatorDescriptor

use of org.apache.hyracks.storage.am.common.dataflow.TreeIndexBulkLoadOperatorDescriptor in project asterixdb by apache.

the class SecondaryIndexOperationsHelper method createTreeIndexBulkLoadOp.

protected TreeIndexBulkLoadOperatorDescriptor createTreeIndexBulkLoadOp(JobSpecification spec, int[] fieldPermutation, IIndexDataflowHelperFactory dataflowHelperFactory, float fillFactor) throws AlgebricksException {
    TreeIndexBulkLoadOperatorDescriptor treeIndexBulkLoadOp = new TreeIndexBulkLoadOperatorDescriptor(spec, secondaryRecDesc, fieldPermutation, fillFactor, false, numElementsHint, false, dataflowHelperFactory);
    AlgebricksPartitionConstraintHelper.setPartitionConstraintInJobSpec(spec, treeIndexBulkLoadOp, secondaryPartitionConstraint);
    return treeIndexBulkLoadOp;
