-----------------------------------
Summary: Support for Group concat function in phoenix
Key: PHOENIX-996
URL: https://issues.apache.org/jira/browse/PHOENIX-996
Project: Phoenix
Issue Type: Improvement
Reporter: Nitin Kumar
Priority: Blocker
Hi James,
Its really great to see the promptness by phoenix team for resolving certain
critical issues/enhancement(particularly all my issues resolved till date).
ex:- https://issues.apache.org/jira/browse/PHOENIX-136
I am again stuck with one use case(and we are in advanced stage of our product
which uses phoenix for aggregation etc)
Use case: Support for group concat
ex(SQL query):-
SELECT student_name,
GROUP_CONCAT(DISTINCT test_score
ORDER BY test_score DESC SEPARATOR ' ')
FROM student
GROUP BY student_name;
Is it possible to achieve this in phoenix?
Note:- This is supported in Hive. They have something called as collect_set()
Regards,
Nitin
