Hi all,
I have 10 million records in my postgres table.I am running the database in amazon ec2 medium instance. I need to access the last week data from the table.
It takes huge time to process the simple query.So, i throws time out exception error.
query is :
select count(*) from dealer_vehicle_details where modified_on between '2012-10-01' and '2012-10-08' and dealer_id=270001;
After a lot of time it responds 1184 as count
what are the ways i have to follow to increase the performance of this query?
The insertion also going parallel since the daily realtime updation.
what could be the reason exactly for this lacking performace?
