Which is the best way to fetch records from table with > 10 million rows of data?

Question

I am working with postgres and php.

I have tens of millions of records in my table and want hourly,monthly and yearly data from that table.

If I select hour then it should result hourly records within selected range.

Should I implement Views, temporary tables or something else whatever useful for this for better performance?

Answer 1

Have you created any indexes on the date columns?

If you are aggregating the data for a report, then you could create a batch job that populates an Aggregated Fact Table each night.
