Su Ralph created KYLIN-1398:
-------------------------------
Summary: Query explanation
Key: KYLIN-1398
URL: https://issues.apache.org/jira/browse/KYLIN-1398
Project: Kylin
Issue Type: Improvement
Components: Query Engine
Reporter: Su Ralph
Assignee: liyang
Fix For: 2.0
When troubleshooting kylin query, we could user "Insight" tab to issue query,
then checking the kylin.log. This definitely the right way, but make it only
available to kylin admin who can access the kylin log.
Since most query system provide query explanation(same as calcite), Kylin might
also output query explanation in response. Say when issue query with
explain=true , the query response would return structured explanation, like how
many htable touched, how many records read from each htable and the time
consumption.
Both kylin owner and user should benefit from such feature.
