Example 66 with ResultRow

use of org.apache.druid.query.groupby.ResultRow in project druid by druid-io.

the class GroupByBenchmark method queryMultiQueryableIndexWithSpillingTTFR.

 * total query processing time. This measure is useful since the Broker can start merging as soon as the first
 * result is returned.
