Example 6 with Aggregation

use of org.apache.hadoop.hive.ql.exec.vector.expressions.aggregates.VectorUDAFCount.Aggregation in project hive by apache.

the class VectorUDAFBloomFilter method iterateNoNullsSelectionWithAggregationSelection.

private void iterateNoNullsSelectionWithAggregationSelection(VectorAggregationBufferRow[] aggregationBufferSets, int aggregateIndex, ColumnVector inputColumn, int[] selection, int batchSize) {
    for (int i = 0; i < batchSize; ++i) {
        int row = selection[i];
        Aggregation myagg = getCurrentAggregationBuffer(aggregationBufferSets, aggregateIndex, i);
        valueProcessor.processValue(myagg, inputColumn, row);
    }
}

Example 7 with Aggregation

use of org.apache.hadoop.hive.ql.exec.vector.expressions.aggregates.VectorUDAFCount.Aggregation in project hive by apache.

the class VectorUDAFBloomFilter method getAggregationBufferFixedSize.

@Override

    if (bitSetSize < 0) {
        // Not pretty, but we need a way to get the size
        try {
            Aggregation agg = (Aggregation) getNewAggregationBuffer();
            bitSetSize = agg.bf.getBitSet().length;
        } catch (Exception e) {
            throw new RuntimeException("Unexpected error while creating AggregationBuffer", e);

    }
    // BloomFilter: object(BitSet: object(data: long[]), numBits: int, numHashFunctions: int)
    JavaDataModel model = JavaDataModel.get();
    long bloomFilterSize = JavaDataModel.alignUp(model.object() + model.lengthForLongArrayOfSize(bitSetSize), model.memoryAlign());
    return JavaDataModel.alignUp(model.object() + bloomFilterSize + model.primitive1() + model.primitive1(), model.memoryAlign());
