Examples with Row org.apache.druid.data.input.Row used on opensource projects

Example 26 with Row

use of org.apache.druid.data.input.Row in project hive by apache.

the class DruidGroupByQueryRecordReader method nextKeyValue.

@Override
public boolean nextKeyValue() {
    if (getQueryResultsIterator().hasNext()) {
        final Row row = getQueryResultsIterator().next();
        // currently druid supports only MapBasedRow as Jackson SerDe so it should safe to cast without check
        currentRow = (MapBasedRow) row;
        currentEvent = currentRow.getEvent();
        return true;
    }
    return false;
}
