I am executing one influxSQL query which is returning result in more than 1 minutes.
Query :
select SUM(call_duration) as total_duration,Count(Distinct(recipient_id)) as total_recipients from xyz where target_id = '1';
Separate queries like
select Count(Distinct(recipient_id)) as total_recipients from xyz where target_id = '1';
select SUM(call_duration) as total_duration from xyz where target_id = '1';
are also takes more than 1 minutes to result the return .
while query
select MAX(call_duration), MIN(call_duration) from xyz where target_id = '1';
Return results very fast, in seconds like 3-4 seconds.
table(measurements) xyz is very large. there are more than 10 million records that matches this where condition.
call_duration and recipient_id are Fields while target_id is Tag
While MIN and MAX function returning results very fast, i suspect why SUM is taking more time?

I think that result should returned in 5-6 seconds
