@Override
@SuppressWarnings("unchecked")
public AggregationResult execute(Aggregator aggregator, Collection<QueryableEntry> entries, Collection<Integer> partitionIds) {
    Aggregator resultAggregator = serializationService.toObject(serializationService.toData(aggregator));
    try {
        for (QueryableEntry entry : entries) {
            resultAggregator.accumulate(entry);
        }
    } finally {
