Hi Rahul,
Currently Kylin only store pre-aggregate data, and no raw data is stored in the
system, so Kylin can only support the aggregate query(has group by clause). For
the no-aggregate query, in order to return better results, Kylin just hack to
output sum of metric columns, for example, the query: select * from
{table_name}, will be hack to "select {all_columns}, sum({metric_column})
group by {all_columns}", so for the metric column doesn't have "sum"
aggregation defined, it will be shown as empty in the result.
