I am trying to understand the performance of certain aspects of native queries in Apache Druid. Is there a way to get the execution plan for a native query? For SQL in Druid we have...
EXPLAIN PLAN FOR SELECT * FORM ds
is there an equivalent command for native queries?
No, there is not (to my knowledge). The EXPLAIN PLAN FOR which you describe will actually show you how your SQL syntax is converted to a native druid query.
There is no equivalent command for native Druid queries, you can collect 'query/time', 'query/segment/time' and other query related metrics Druid emitted to analyze the bottleneck of your queries.
