I am basically running 3 queries with the same where clause.
1. Totals for the entire results(not just the number of rows on the first page)
a. <300 ms
2. Subset of the total records on that page.
a. 1-2 sec
3. Count of the total records for the pagination to show the number of pages
a. 1-2 sec
The queries are generated by Hibernate and I am looking to rewrite them in native SQL
to improve performance.
Any suggestions on how to get the count of all records that could be returned and only
a subset of those records for that page in an optimized fashion? I have no problem using
a widow query or a Postgres specific feature as my app only runs on Postgres.
