------------------------------------------
Summary: Write View Expanded Query to Impala Profiles
Key: IMPALA-12438
URL: https://issues.apache.org/jira/browse/IMPALA-12438
Project: IMPALA
Issue Type: Improvement
Reporter: Manish Maheshwari
When running queries with multi level views, Currently Impala profiles do not
log the expanded query with views replaced. This makes it harder to understand
the actual tables involved in the query and also to understand the complxity of
the views used
A change would be to write into the query profiles the original query and the
same query with all the views replaced with their actual definitions -
e.g.
{code:java}
Analyzed query: SELECT * from db.table limit 10
Expanded query: Select * from (select d.c1, d.c2, e.c3 from d inner join
(select c3 from f inner join .... ) e on d.c1 = e.c2 left join ..... ) limit
10 {code}
